Strength, Health, & the Art of Living Well
Why the New Resistance Training Guidelines Feel Both Important and Underwhelming
The American College of Sports Medicine (ACSM) recently released an updated position stand on resistance training for healthy adults. A position stand is essentially an official summary of the current evidence that organizations use to guide recommendations for practitioners, coaches, and the general public. This update revisits and expands on ACSM's 2009 guidance by synthesizing a large body of research on how different training variables affect outcomes like strength, muscle growth, power, and physical function.
When I first saw people discussing the update, I expected the conclusions to feel more surprising. Instead, a lot of them sounded like things many evidence-informed coaches already accept. You do not need to train to failure every set. Muscle can grow across a wide range of loads. Frequency is mostly a way to distribute weekly volume. Machines and free weights can both be useful. Periodization is not automatically superior for every lifter in every situation.
My first reaction was not disagreement as much as confusion. Why was this being treated like big news?
The answer, I think, is that the update is less revolutionary as an advanced coaching document and more important as an institutional correction. It moves resistance-training guidance away from rigid prescriptions and toward a more flexible understanding of what actually drives adaptation.
In other words, the big shift is not that the old methods stopped working. It is that many of the old rules should no longer be treated as universal requirements.
What the Paper Actually Did
The American College of Sports Medicine released an updated position stand on resistance-training prescription for healthy adults. This paper updates their 2009 position by summarizing a large body of research on how different resistance-training variables affect strength, hypertrophy, power, muscular endurance, and physical function.
This was not one new training study. It was an overview of reviews, meaning the authors looked at existing systematic reviews and meta-analyses to determine what the broader literature says about resistance training.
That distinction matters because the paper is not trying to answer the same question a coach might ask when writing a program for an advanced lifter or athlete.
The paper is asking a broad question:
What resistance-training variables consistently improve outcomes across healthy adults?
A coach is often asking a more specific question:
What does this individual need, at this stage of development, with this goal, this recovery capacity, this training history, and this timeline?
Both questions are useful, but they are not the same question. That is part of why the conclusions can feel both important and underwhelming at the same time.
The Big Shift: From Rules to Ranges
Resistance training has traditionally been taught through very specific rules.
Train each muscle two or three times per week. Use a certain repetition range. Rest a certain amount of time. Progressively overload the movement. Periodize the program. Use enough volume. Train through a full range of motion. Choose the right exercises. Follow the right structure.
None of those recommendations are inherently bad. In many cases, they are useful. The problem is that useful recommendations often become universal laws.
The new position stand seems to challenge that way of thinking.
It does not say that programming variables are meaningless. It says that many resistance-training approaches can improve muscle, strength, and function when compared with doing nothing. Once training is hard enough, consistent enough, and organized around the goal, fewer variables appear to have one universally superior setting.
That is the difference between saying:
“This is a useful way to train.”
And saying:
“This is the only correct way to train.”
The first statement may be true. The second is much harder to defend.
Effective Is Not the Same as Optimal
One of the most important distinctions in the paper is the difference between training that is effective and training that is optimal for a specific outcome.
For general health and function, many forms of resistance training work. Free weights, machines, elastic bands, bodyweight exercises, circuit training, home-based training, and other approaches can all produce meaningful improvements if they are performed consistently and with enough effort.
That does not mean every program is equally good for every goal.
If the goal is maximal strength, heavier loading becomes more important because strength is highly specific to producing force against heavy loads. If the goal is hypertrophy, weekly volume and sufficient effort appear more important than forcing one exact repetition range or training frequency. If the goal is power, the program needs to include faster, more explosive intent rather than only slow, grinding repetitions.
This is where the paper can be misread.
It is not saying the details do not matter. It is saying the details matter most when they are attached to a specific outcome.
A beginner trying to become healthier and stronger does not need the same level of programming precision as an advanced lifter trying to peak a competition lift, bring up a weak muscle group, or manage fatigue across a long training cycle.
The Traditional Rules That Became Tools
The most useful way to understand the update is this:
A lot of traditional resistance-training rules should now be viewed as tools.
Frequency is not magic. It is a tool for distributing weekly volume and managing session quality.
Failure is not mandatory. It is a tool for measuring and applying effort.
Tempo is not a secret hypertrophy mechanism. It is a tool for controlling execution, reducing momentum, and keeping tension where you want it.
Exercise selection is not about choosing universally superior movements. It is a tool for directing stress toward the tissues and skills you are trying to improve.
Rest periods are not inherently anabolic or non-anabolic. They are a tool for controlling performance, fatigue, density, and training quality.
Machines and free weights are not moral categories. They are tools that load the body differently and should be chosen based on the goal, the person, and the context.
Periodization is not a magic ingredient. It is a tool for organizing training stress over time.
This does not make the variables unimportant. It makes them conditional.
The question is not, “What is the rule?”
The better question is, “What problem is this variable solving?”
Why the Periodization Finding Feels Strange
The periodization conclusion is probably one of the easiest parts of the paper to misunderstand.
At first glance, it can sound like the authors are saying periodization does not matter. That can feel wrong to anyone who has trained or coached beyond the beginner stage.
But the better interpretation is more specific.
The paper does not show that planning training over time is useless. It shows that formal periodized programs have not consistently outperformed nonperiodized programs for broad strength and hypertrophy outcomes across the available reviews.
That makes more sense when you consider who is often included in resistance-training research.
Many studies involve untrained or minimally trained participants. For those people, almost any sensible resistance-training program can work. A novice can gain strength from improved coordination, better movement skill, increased confidence, and simply being exposed to loading for the first time. Their threshold for adaptation is low.
In that context, a basic program can produce similar short-term progress to a more formally periodized program.
But that does not mean periodization has no value for people with a higher training age or athletic aspirations.
As someone becomes more advanced, the training problem changes. The issue is no longer just getting exposed to resistance training. The issue becomes continuing to create a stimulus while managing fatigue, joint stress, performance demands, skill practice, recovery, and long-term progression.
That is where periodization still matters.
It can help organize volume, intensity, exercise selection, specificity, variation, and recovery across time. It can help an athlete shift from general preparation to more specific performance. It can help someone emphasize hypertrophy in one phase, strength in another, and peaking in another. It can help manage competing qualities that cannot all be maximally trained at once.
So the takeaway should not be:
“You do not need periodization.”
The better takeaway is:
“Not everyone needs formal periodization to make progress, especially beginners. But advanced lifters and athletes often need some form of organized training structure because their problems are more complex.”
Periodization may not be a direct driver of adaptation by itself. It is a way of organizing the variables that drive adaptation.
Why This Feels Underwhelming
If you already follow modern hypertrophy and strength research, a lot of the paper may feel familiar.
It is already fairly well accepted that hypertrophy can occur across a wide range of loads if sets are taken close enough to failure. It is already common to say that failure is not required on every set. It is already known that frequency is often a way to distribute volume rather than an independent growth trigger. It is already accepted by many coaches that machines can be excellent tools, especially for hypertrophy. It is already reasonable to say that beginners do not need complex periodized programs.
So why does the update matter?
It matters because official guidelines tend to lag behind what experienced coaches and researchers are already discussing. The position stand is not necessarily introducing a brand-new way to train. It is updating the official language around training.
That is still important.
Many people still believe resistance training must follow a narrow template to count. They think they need the perfect split, the perfect rep range, the perfect exercise selection, the perfect progression model, or the perfect periodized plan before they can start.
This paper pushes back against that.
For the general population, the most important message is that resistance training is more flexible than many people think. You do not need to train like a bodybuilder, powerlifter, or athlete to receive meaningful benefits. You need a sustainable way to challenge your muscles consistently.
That is not underwhelming for the person who has been intimidated by the weight room for years.
What This Means for Beginners
For beginners, the message is simple.
Start.
Do not wait until you understand every training variable. Do not wait until you know the perfect split. Do not obsess over whether you should use machines or free weights. Do not worry about whether your program is formally periodized.
Train the major muscle groups. Use exercises you can perform safely and consistently. Work hard enough that the sets are challenging. Add weight, repetitions, sets, or control over time when appropriate. Recover well enough to repeat the process.
For a beginner, consistency matters more than complexity.
A simple program done consistently will outperform a sophisticated program that someone cannot understand, recover from, or maintain.
What This Means for More Advanced Lifters
For advanced lifters, the message is different.
This paper should not be used as an excuse to abandon structure. The fact that many variables do not show universal superiority across broad research does not mean they are irrelevant in advanced training.
As training age increases, the margin for progress becomes smaller. The workload required to create adaptation often becomes higher, while the cost of that workload also increases. Fatigue becomes more meaningful. Exercise selection becomes more specific. Recovery becomes more limiting. Weak points become harder to address. Performance goals become more precise.
At that point, programming variables matter because they solve specific problems.
Frequency may be adjusted to distribute volume more effectively.
Exercise selection may be used to bias a lagging muscle or reduce joint stress.
Failure may be used sparingly to increase stimulus without overwhelming recovery.
Volume may be cycled to manage fatigue.
Intensity may be emphasized when strength expression becomes the priority.
Periodization may be used to organize all of those variables across time.
For advanced trainees, the lesson is not that programming matters less. It is that programming should be justified by the goal rather than inherited as dogma.
What This Means for Coaches
For coaches, the update is a reminder to be more precise with language.
There is a difference between saying:
“I like this approach.”
“This approach works well for this person.”
“This is useful for this goal.”
And:
“Everyone needs to train this way.”
A lot of coaching errors come from turning useful tools into universal rules.
A coach should be able to explain why a variable is being used. Why this frequency? Why this exercise? Why this rep range? Why this rest period? Why this phase? Why this progression model?
If the only answer is, “Because that is what a good program is supposed to include,” the reasoning probably needs to be sharpened.
The value of coaching is not just knowing the variables. It is knowing when each variable matters, when it does not, and how to apply it to the person in front of you.
The Real Takeaway
The new ACSM position stand does not mean programming no longer matters.
It means the field is becoming more careful about which programming rules are truly universal and which are context-dependent.
For the general population, the most important message is that resistance training works across a wide range of approaches. You do not need a perfect program to begin. You need a repeatable one.
For beginners, that should be freeing.
For coaches, it should be humbling.
For advanced lifters and athletes, it should not be misread as a dismissal of structure. The more specific the goal and the more trained the person, the more important it becomes to organize training intelligently.
The real update is not that resistance training has changed.
The update is that the rules have become less rigid.
Many of the things we once treated as requirements are better understood as tools. Their value depends on who is training, what they are training for, and what problem the program is trying to solve.
Why High-Glycemic Post-Workout Meals May Work Against Muscle Growth
Glycemic load is a term used to describe the effect a food has on blood sugar. The higher the glycemic load, the more that food raises blood sugar and insulin.
Over the years, there has been growing public awareness around glycemic load and how it affects health. More people understand that certain foods spike blood sugar more aggressively than others, and that repeated blood sugar and insulin spikes can affect metabolism over time.
However, this topic is still widely misunderstood, especially in sports nutrition.
One of the most common assumptions is that high-glycemic protein meals promote muscle gain. Many commercial protein products are packed with sugar and marketed around the idea that deliberately spiking insulin after training will help drive more nutrients into muscle and produce better growth.
The logic sounds simple. Insulin is an anabolic hormone, so if you spike insulin after training, it should increase protein deposition in the muscle and improve muscle gain.
That is the idea.
But that is not necessarily what happens in real life.
In real life, high-glycemic protein meals may be counterproductive for muscle. There are two main reasons why.
First, exercise causes a temporary disruption in glucose utilization in the muscle. This is related to muscle microtrauma, or the wear and tear that occurs in muscle tissue during training. Immediately after exercise, the muscle may not tolerate a high-glycemic meal as well as people assume.
The post-workout window is often described as a time when the body can handle anything because the muscles are “primed” for nutrients. But that idea may be too simplistic. Training creates demand, but it also creates stress. The body still needs to manage inflammation, tissue damage, glucose handling, and recovery.
Second, high-glycemic meals can impair insulin function, disrupt muscle mTOR signaling, and interfere with muscle protein synthesis. mTOR is one of the key biological mechanisms involved in building muscle. If insulin sensitivity is impaired, mTOR cannot be fully activated in the way people want.
This is where the insulin-spike theory starts to fall apart.
Insulin matters, but more insulin is not always better. The goal should not be to constantly force the largest possible insulin response. The goal should be to maintain insulin sensitivity so the body can respond properly to the insulin it produces.
There is a major difference between using insulin effectively and chronically overspiking it.
Chronic intake of high-glycemic meals has been shown to cause hyperinsulinemia, a condition where insulin is repeatedly or chronically elevated. Hyperinsulinemia has been linked to uncontrollable fat gain, damage to insulin receptors, and harm to the muscular system.
That matters because muscle growth does not happen in isolation. It depends on the health of the entire metabolic system. If the diet repeatedly drives excessive insulin responses and worsens insulin sensitivity, the body may become less efficient at using nutrients properly.
In that environment, the same meal that was supposed to help build muscle may contribute to fat gain and metabolic dysfunction instead.
This does not mean carbohydrates are bad. It does not mean insulin is bad. It does not mean post-workout nutrition does not matter. The issue is the assumption that a high-sugar, high-glycemic protein meal is automatically the best way to support muscle growth.
Muscle growth requires training stimulus, adequate protein, enough total calories, recovery, and proper nutrient timing. But none of that requires turning every post-workout meal into a blood sugar spike.
A better approach is to support recovery without overwhelming the body. That means prioritizing high-quality protein, choosing carbohydrates based on the person’s training, goals, and insulin sensitivity, and avoiding the belief that more sugar automatically means more muscle.
The body builds muscle through coordinated signaling, not through brute-force insulin spikes.
High-glycemic post-workout meals may sound effective because they appear to match a simple anabolic story: spike insulin, drive nutrients, build muscle. But the body is more complex than that. If insulin sensitivity is impaired, glucose handling is disrupted, and mTOR signaling is compromised, the strategy can work against the very outcome it is supposed to support.
The goal after training is not simply to raise insulin as high as possible.
The goal is to create the internal conditions that allow the body to recover, repair, and build muscle efficiently.
Exercise Keeps You Younger at the Cellular Level
Most people think about exercise in terms of how it changes the body on the outside. They think about weight loss, muscle, strength, endurance, or how they look in the mirror.
But exercise also changes the body on the inside.
Research shows that adults who regularly engage in intense exercise have significantly longer telomeres. Telomeres are the protective caps on the ends of chromosomes. They help protect genetic material as cells divide, and they are often discussed as one marker connected to biological aging.
That matters because telomere length gives us a way to think about aging beyond the number of birthdays someone has had. Two people can be the same chronological age, but their bodies may not be aging at the same rate internally.
In a 2017 study using NHANES data, researcher Larry A. Tucker found that adults who engaged in high levels of physical activity had significantly longer telomeres than those who were less active. According to the research, people who exercised regularly appeared to be a full decade younger than their peers at the cellular level.
That is a powerful idea.
Exercise is not just about burning calories. It is not just about looking better, building muscle, or improving performance. It is one of the most important signals we can send the body if we want to preserve function, resilience, and biological youth.
The body adapts to what we ask of it. When we regularly engage in intense exercise, we are giving the body a reason to maintain itself. We are asking it to preserve muscle, improve cardiovascular function, regulate blood sugar, support mitochondrial health, and keep tissues responsive.
Telomeres are one way to see that the benefits of exercise may reach deep into the biology of aging.
This does not mean exercise makes someone immortal. It does not mean training can stop every part of the aging process. But it does suggest that regular intense physical activity is associated with measurable differences in cellular aging.
That should change how we think about exercise.
Exercise is often treated like an optional lifestyle habit, something people try to fit in when they have time. But if regular intense exercise is connected to longer telomeres and a younger cellular profile, then movement belongs in the same conversation as longevity, prevention, and long-term health.
The goal is not simply to live longer. The goal is to live longer with a body that still works.
Strength, endurance, mobility, and metabolic health all matter because they determine what kind of life a person can physically participate in as they age. Longer life has less value if the body loses the capacity to move, lift, walk, recover, and engage with the world.
Exercise helps protect that capacity.
The larger point is simple: movement is not only something we do for fitness. It is something we do to preserve the body’s ability to keep functioning well over time.
If you want to age better, exercise cannot be an afterthought. It has to become part of the way you live.

A Case for the Hyperextension
In many gyms, the hyperextension has a bit of a therapeutic image. If you do this exercise, it is because your physical therapist has advised you to. But real members of the iron tribe who do not need a physiotherapist, of course, do not do the hyperextension. They are going to deadlift. Yes right? Thought wrong, Norwegian sports scientists discovered.
Why you should include the hyperextension in your workouts

But real members of the iron tribe who do not need a physiotherapist, of course, do not do the hyperextension. They are going to deadlift. Yes right? Thought wrong, Norwegian sports scientists discovered.
Study
Vidar Andersen, of the Western Norway University of Applied Sciences, in the Journal of Sports Science and Medicine, compared the effects of the hyperextension [using the term Roman chair extension] with those of the Romanian deadlift and the machine back extension.
Andersen had the exercises performed by 15 female students, who had been training with weights for quite some time, with a load with which 6 reps were possible. He stuck electrodes on the subjects' bodies so that he could see how hard muscles such as the erector spinae, the biceps femoris or the gluteus maximus had to work during the upper and lower part of the movement.
Results
The figure below shows the activation of the muscle groups. Of these three exercises, the hyperextension appears to provide the best stimuli for the muscle groups. The Romanian deadlift comes in second.
Practical application
"For athletes and recreationally active people aiming to optimize the neuromuscular activation of the glutes and hamstring, we would particularly recommend the Roman chair exercise", writes Andersen.
"This exercise was in general more effective in activating these muscles, likely due to the biomechanical properties of the exercise creating a consistently large torque throughout the whole range of motion, and particularly in the upper part. It is also easier to perform with proper technique than the Romanian deadlift."
"Machine back extension was clearly inferior to the other two exercises."
Honor the deadlift
That's not to say Andersen thinks serious athletes should forget about the Romanian deadlift. The exercise certainly has its qualities.
"The Romanian deadlift maximizes its torque in a flexed hip position", Andersen continues. "As the hip is extended, the torque continuously decreases, allowing for increased velocity. These biomechanics would simulate running, and especially the top speed phase, where the hip torque is greatest in the late swing phase where the hip is flexed."
"Therefore, we recommend athletes and recreational trained to consider the purpose of the exercises before choosing which one to include in their weekly resistance-training program."
Strength Training works better than Cardio for fat loss
Men who do strength training keep their fat percentage lower in the long term than men who run, cycle or do other aerobic exercise. Epidemiologists at the University of Harvard came to this conclusion after following 10,500 men for 12 years.
Strength training fights belly fat better than aerobic training
Men who do strength training keep their fat percentage lower in the long term than men who run, cycle or do other aerobic exercise. Epidemiologists at the University of Harvard came to this conclusion after following 10,500 men for 12 years.
Strength training and body fat
At first glance you'd think that aerobic forms of exercise such as running, cycling and rowing would offer better protection against building up excess fat than strength sports do. A weights workout burns a couple of hundred kilocalories at most, while an hour of intensive aerobic training will easily help you burn eight hundred kilocalories.
On the other hand though: after the age of thirty you lose a little bit of muscle mass each year. Because every kilogram of muscle mass you lose also lowers your daily calorie burning by a couple of dozen kilocalories, the older you are, the more easily you put on weight. You can stop this process by doing strength training. If you train really hard and eat enough protein, you can even build up more muscle mass as you age. Aerobic forms of exercise contribute little to building up more muscle mass.
Study
The researchers used data on over 10,000 healthy men that had been gathered between 1996 and 2008 in the Health Professionals Follow-Up Study, including information on how the waist measurement of the participants had changed over the study period. When the study began in 1986, the participants were aged between 40-75.
"Because aging is associated with the loss of skeletal muscle mass, relying on body weight is insufficient for the study of healthy aging", explained Rania Mekary, the first author of the study, in a press release. [harvard.edu December 22, 2014] "Measuring waist circumference is a better indicator of healthy body composition among older adults."
The researchers divided the men up according to the amount of exercise they got. First the researchers looked at the amount of moderate to vigorous aerobic activity [MVAA] the men got daily. The norm is at least half an hour a day of this type of exercise.
Then the researchers looked at the number of minutes a day the men devoted to strength training.
Results
Strength training offered more protection against a growing waist circumference than moderate to vigorous aerobic activity did, according to the figure below.
During the period that the researchers monitored the men, their waist measurement increased by an average of 6.6 cm. Strength training reduces this increase by 3 cm. According to this study, that happens regardless of whether you adhere to the norm for moderate to vigorous aerobic activity or not.
The researchers even calculated that if the participants had done 20 minutes of strength training daily during the 12 years of the study instead of 30 minutes of aerobic activity, they would have lost another 0.34 cm from their waist measurement. It would have been even better if they had done 20 minutes strength training a day instead of of watching TV for 30 minutes: that would have resulted in a reduction of 0.76 cm on the waist measurement.
Conclusion
The leader of the project, Frank Hu, emphasised in a press release [harvard.edu December 22, 2014] that the study does not show that aerobic forms of exercise are therefore no longer necessary. Aerobic exercise has positive effects on the cardiovascular system that strength training does not have.
"This study underscores the importance of weight training in reducing abdominal obesity, especially among the elderly", said Hu. "To maintain a healthy weight and waistline, it is critical to incorporate weight training with aerobic exercise."
Intense Workouts 2xWeek Reduce Burnout from Office Work
Employees, freelance workers and entrepreneurs are less likely to succumb to a burnout if they do an intensive training session twice a week. Psychologists at the University of New England in Australia discovered that both strength training and cardio training reduce the chances of having a burnout.
Resistance training and cardio training offer protection against burnout
Employees, freelance workers and entrepreneurs are less likely to succumb to a burnout if they do an intensive training session twice a week. Psychologists at the University of New England in Australia discovered that both strength training and cardio training reduce the chances of having a burnout.
Burnout
The term burnout was coined in 1975 by the American psychologist Christina Maslach. According to Maslach a burnout has three components.
The most obvious of these is emotional exhaustion, followed by depersonalisation. Depersonalisation is when someone develops a negative and often cynical attitude towards their colleagues, the organisation where they work and the work itself. The third component in a burnout is that someone's sense of personal accomplishment decreases.
Study
The Australian researchers wanted to find out whether doing sports would reduce the likelihood of developing a burnout, so they got 29 subjects, aged between 19 and 68, to train three times a week for a period of four weeks. Each session lasted at least half an hour. Twenty subjects did cardio training and 9 did weight training. A control group of 20 people did no sports at all.
Results
At the beginning and end of the four weeks the researchers got the subjects to fill in a questionnaire designed in the 1980s by Maslach to measure burnout. The figures below show that cardio training reduced emotional exhaustion and that resistance training boosted the subjects' personal accomplishment.
In addition, resistance training and cardio training both increased the feeling of psychological wellbeing and reduced the amount of stress that the subjects reported.
Conclusion
"This research provides a valuable supplement that attests to the significant benefit of exercise to both individuals and organisations in increasing well-being, reducing perceived stress, and reducing burnout", the researchers wrote.
"The positive effect of resistance training on personal accomplishment and the psychological distress reducing effects of cardiovascular exercise are exciting extensions of the current literature which, if replicated, can support health and fitness professionals in developing exercise programs for optimal physical and psychological health."

Hack your Endurance with Rhodiola & Ginkgo
Rhodiola and ginkgo combination boosts endurance (no training required)
Supplementation with extracts of Ginkgo biloba and Rhodiola crenulata increases the stamina of young men. This is shown in a human study published in 2009 in the Chinese Journal of Integrative Medicine.
Study
The researchers, at the University of Hong Kong, divided 67 young men into 2 groups. For 7 weeks, they gave the men in one group placebo capsules and the men in the other group capsules containing extracts of Ginkgo biloba and Rhodiola crenulata in a ratio of 1: 9.
The men took 4 capsules each day, each containing 270 milligrams of extract mixture. They took 2 capsules with breakfast and 2 capsules with dinner.
Results
The supplement increased the men's stamina. The subjects in the experimental group managed to cycle longer, and that may have been due to the increase in their bodies' ability to absorb oxygen. [VO2max]
Supplementation did not affect the test subjects' testosterone levels, but it did prevent cortisol levels from rising after exercise. That may mean that the men recovered faster.
Conclusion
"The present findings have provided evidence supporting the use of Rhodiola crenulata and Ginkgo biloba combined supplement for improving the endurance performance by increasing oxygen consumption and protecting against fatigue", summarize the researchers.
According to Russian animal study, extracts from both plants improve endurance, albeit in different ways. [Bull Exp Biol Med. 2003 Dec;136(6):585-7.]
Women and Men respond similarly to strength trianing
Women's upper body muscles respond to strength training just as well as men's
The extent to which women can strengthen the muscles in their upper body through strength training is the same as the extent to which men can do this. However, this does not imply that women can easily reach the strength level of men who work out.
Study
In 2016, Brazilian sports scientist Paulo Gentil published a study in which he got 44 male and 47 female students to do a full-body workout twice a week for 10 weeks.
The workout consisted of basic exercises such as leg press, leg curl, chest press and lat pulldown. The subjects did 3 sets of each exercise with a weight that allowed for 8-12 repetitions. The subjects rested for 2 minutes between sets.
Before and after the training period, the researchers determined the torque that the test subjects could develop during a biceps curl. 'Torque' is what athletes in the gym often refer to as 'force'.
Results
In absolute terms, the men gained more strength than the women [left in the figure below]. But in relative terms, in terms of progression over the strength already present before the training program began, the progression of the men was similar to that of the women [bottom right].
Conclusion
"Despite the physiological and hormonal differences between sexes, women demonstrated the same relative strength gains compared to men [...]", writes Gentil.
"It appears there is presently no evidence of a need to design different resistance training protocols to men and women. [...] One should not expect to find limitations in upper body strength development in women."

The Importance of Strength Training in Combat Sports
Strength is an attribute that cannot be significantly improved through the practice of participating in Combat Sports, therefore it makes strength training a wise investment, particularly if you want to win. The purpose of increasing strength is to develop physical capacities necessary to handle the unpredictable nature and stressors of the sport. Athletes need to be prepared for all aspects of physical combat including punching, kicking, takedowns, takedown defense, arm bars, guillotine, grappling, and clinching, not to mention proper conditioning and muscle endurance. A simpler way to say it would be, to achieve victory an athlete needs to be faster, more explosive and last longer than their opponent. Also, let me make it clear before I go any further, strength does not replace technique — wrestlers should prioritize wrestling, just as martial artists should ultimately work to perfect their discipline — but improving strength will transfer to better technical performance (e.g., technique) on the mat or in the cage.
As a Strength Coach I look at strength training as a way to improve performance by increasing strength, whereas those who participate in Combat Sports look to improve performance through perfecting technique. Classically, there has been little crossover combining the two disciplines — with the exception of people like Bruce Lee, who found technique more useful in concert with strength — however, as Combat Sports like Wrestling and Mixed Martial Arts (MMA) continue to grow in popularity, attracting ever more skilled fighters, the sole focus on advancing technique without increasing strength is misguided. There will plenty of people who disagree, yet for those, I challenge you to find one detriment that comes with being stronger. I couldn’t find any, which is why I believe that strength is the mother of all qualities.
“Helen Maroulis defeated Saori Yoshia to win a gold medal in Women’s Wrestling at the 2016 Olympics in Rio after incorporating strength training into her regimen. Yoshia hadn’t lost in 10 years prior to her match with Maroulis; upon walking off the mat after her loss, she was overheard as saying “[Helen] is too strong for me.” Only six months prior, Maroulis was unable to do something as fundamental as a pull-up. Despite advancing to the highest level in her sport — US Olympic Wrestling Team — her technical skill lacked the expression of strength, which was her literal weakness and the one thing holding her back from success on the world’s highest stage.”

“I don’t want to lift weights because I will get too big and bulky, it will make me slow”
Avoiding the weightroom for fear of it making you big, bulky and slow, fly’s in the face of basic physiology. This misguided idea has lead to a heavy reliance on bodyweight exercises or kettlebell circuit training as their primary methods of physical preparation. This style of training works primarily against strength and power development by prioritizing slow-twitch/endurance based muscle fibers at the expense of fast-twitch/explosive muscle fiber development which would provide the power to deliver a knockout or the explosiveness to execute a takedown.
“I don’t want to lift weights because I only need to prioritize my cardio”
Improving strength makes all imposed demands easier, this includes those placed upon the cardiovascular system. Simply put, having stronger muscles allows the athlete to complete any task with less effort (i.e., less energy) and therefore have more reserve. More specifically, when developing the cardiovascular system it is necessary to understand that energy systems are optimized given the demands of the sport. Prioritizing only one energy system with long-slow distance running works against high threshold muscle fibers making explosive movements more taxing and decreases the ability to withstand a blow to the head due to losses in strength. Furthermore, the over-reliance on easy work generally comes with a sacrificing of quality for quantity, further increasing injury risk. A study on American Boxers published in 1990 concluded that an association could be made between lower body overuse injuries and the jogging and rope jumping the boxer did for preparation.
“I don’t want to lift weights because it will decrease my flexibility”
Flexibility is passive, what difference does it make if you’re athlete can stretch themselves in to a position. What really matters is that an athlete is able to demonstrate strength throughout the entire range of motion. You can spend hours doing static stretching or you can perform full range of motion exercises during your strength training. With proper range of motion and antagonistic muscle group training an athlete can optimize range of motion throughout a joint as there is equal balance between muscle groups.
“I don’t want to lift weights because I can get hurt”
Guess what, you’re in a full contact sport! Seriously though, many sport-related injuries stem from muscular imbalances — discrepancies in strength between opposing muscle groups — due to the repetitive stress of consistently overloading the same patterns without addressing the importance of structural balance. There is an optimal balance of strength between muscle groups that control a joint, but if the muscles on one side of the joint are disproportionately stronger than muscle on the opposing side, injury risk can increase. For more on structural balance, check out: Importance of Structural Balance for Injury Prevention.
“I don’t want to lift weights because it is not sport’s specific”
Many people get into trouble by thinking traditional strength training exercises and methods don’t translate well into improving performance because they don’t use the same movements that are part of an athletes technique and skill. Somewhere along the line “functional training” became interchangeable with “specificity” or “sport’s specific training” which tries to replicate the specific motor patterns and skill from the sport and add some component of resistance or instability to it. They argue that such efforts are necessary to make an exercise more transferable to on the mat performance. While goodhearted, this is a misguided attempt. For example Boxing Strength Coach Moritz Klatten had the following to say about using bands to simulate punching movements…
it is a terrible idea because the bands provide the most tension at the end of the movement, and as such they will negatively impact coordination patterns by decelerating the arms toward the end of the movement rather than the biceps. When the fighter goes back to punching without bands, they often decelerate too early or late — deceleration too late causes harmful hyperextension of the elbow, and too early reduces punching power.
The last thing you want to do as a Strength Coach is to work against the progress of your athlete or increase risk of injury. The same logic can be applied to the flawed theories behind unstable surface training or the belief that ladder drills will make an athlete more agile (see Ladder Drills Do Not Increase Sport Performance).
We need to get away from the idea that “sport specific” exercises are necessary for Combat Sport training — or most sports, for that matter — because the only sports where specific exercises directly translate to performance are Olympic Weightlifting (Snatch and Clean & Jerk), Gymnastics (Pull-Ups and Dips) and Powerlifting (Squat, Bench and Deadlift). It is important to understand that while slight variabilities in origin or insertions may exist from person to person, muscles function fundamentally the same across all populations, whether you are an elite UFC fighter or an office worker. Therefore, improving a combat athlete’s performance with strength training is not a matter of finding the best “functional” exercise to replicate a “sport’s specific movement,” but instead it is developing a proper understanding of biomechanics and applying that knowledge towards a strength training program that selects exercises to train muscles in the best way possible… for this fundamentals work best.
Push. Pull. Hinge. Extend. Rotate. Carry. Sprint.
While wrestling requires greater isometric strength because of the holds, Judo requires greater eccentric strength to complete throws and Boxing/MMA requires powerful concentric contractions for striking, the fundamentals are undeniably the best place to start. The following are a fundamental list of exercises that will better prepare the Combat Sport athlete for their next competition:
Push: Incline Press
The Incline Press is key to building strength in the chest and elbow extensors. Pressing motions are necessary for the development of punching power as they are powerful internal rotators of the Humerus (as well as the Lats!). and assisting with defense movements.
Primary muscle groups worked: Chest Musculature, Elbow Extensors, Deltoids
Pull: Pull-Up
The Pull-Up is one of the best upper body exercises to develop strength. Pulling motions are important when trying to controlling an opponent as Lats are used in pulling to pass guard.
Primary Muscles groups worked: Latissimus Dorsi, Biceps Brachii (long head, short head), Brachioradialis, Forearm Flexors
Hinge: Conventional Deadlift
The Conventional Deadlift is the best bang for your buck exercise as it trains the most muscles in the body out of all exercises. It preferentially works the muscles of the Posterior Chain — Hamstrings, Spinal Erectors, Lats, Traps — which is where power is derived from. Traps are used in the shrugging of your shoulders to defend against a rear naked choke.
Primary muscle groups worked: Hamstrings, Gluteal musculature, Spinal Erectors, Latissimus Dorsi, Rhomboids, Trapezius (upper and mid fibers), Core Musculature (Transversus abdominis, Multifidus, Internal and External obliques, Rectus abdominis), Forearm Flexors
Extend: Back Squat
The Back Squat trains the entirely of the legs, hips as well as the low back and core. Anytime you extend your hips or knees, you are using some percentage of what you can squat – Hips extend to apply force on the elbow in an arm bar.
Primary muscle groups worked: Quadriceps, Adductors, Gluteal Musculature, Spinal Erectors, Core Musculature (Transversus abdominis, Multifidus, Internal and External obliques, Rectus abdominis), Gastrocnemius, Soleus
Rotate: External Rotation
The External Rotation exercise is often overlooked but necessary for optimal Structural Balance of the shoulder. Optimal ratios of strength across musculature can improve punching power and the isometric contraction of a clinch.
Primary muscles works: Infraspinatus and Teres Minor
Carry: Heavy Carry
The Heavy Carry challenges the body to move under load. Remaining upright under a heavy load forces strength adaptations in the lower back and core musculature that translate to holding your position on the mat or in the cage. Additionally, grip strength is developed from carrying the weight enabling an athlete to easily establish wrist control.
Primary muscle groups worked: Trapezius (upper and mid fibers), Core Musculature (Transversus abdominis, Multifidus, Internal and External obliques, Rectus abdominis), Spinal Erectors, Forearm Flexors, Gluteal Musculature
Sprint
The Sprint helps to build explosive power through repeated effort. Combat sports revolve around the ability to execute a powerful movement, followed by a brief “rest” usually under an isometric contraction, they deliver another quick movement. While endurance is necessary for this exchange, long-slow distance is not the way to optimally train for such an event. Sprints of long, medium and short distance should be utilized in 400m, 200m, 60m respective.
Primary Energy Systems used: ATP-PC and Lactic
Whether it be pushing, pulling, or extending from a standing position to the same biomechanical patterns from a laying position, combat sport athletes cannot have any weak muscle groups. The stronger athlete with better technique and stamina will win. Therefore, the future of combat sports is not going to be dictated by past practices of bodyweight exercises or distance running, but by those who seek to optimize power and performance as well as injury prevention through structural balancing by adopting a strength training program that allows them to elevate the expression of their technical expertise in a way the competition isn’t ready for… Besides no one ever lost because they said they were “too strong.”

Deep Thoughts, Even Deeper Squats
Are deep squats bad for my knees? The prevailing wisdom on this topic would lead you to believe that squatting below parallel will cause injury to your knees by placing an unusual strain on your ligaments leaving the knee unstable and prone to injury. This theory was brought to light in the late 1950’s when Dr. Karl Klein was trying to understand why there happened to be a rise in the number of colligate football players sustaining serious knee injuries. He suspected it was due to the use of full ROM squats in university strength programs so he crafted a special instrument to analyze the knees of several of these football players who frequently performed deep squats.
In 1961, Dr. Klein released his findings, which recommended the squat be limited to a parallel depth. His reasoning stated that the use of deep squatting is detrimental to athletic development and “should be discouraged from the standpoint of its debilitative effect on the ligamental structures of the knee.” The following year, Dr. Klein’s findings were picked up by Sports Illustrated which became the catalyst to spread the fear of deep squatting. Next the American Medical Association weighed in on the topic cautioning against the use of deep squatting. It went so far as the Marine Corps even eliminated the squat-jumper exercise from its physical conditioning programs.
There has been a lot of pushback on this theory ever since its inception almost 60 years ago. Dr. Klein’s findings have failed clinical replication, even with the use of his special instrument. Fortunately, now in the present day we can use the advancement in exercise science and biomechanics research to settle this debate once and for all.
When we squat, our knee sustains two inversely related forces – shear and compressive – meaning that when the knee flexes during the squat, compressive forces increase while shear forces decrease. These shear forces are measured by how much our bones – femur and tibia – want to slide over one another in opposite directions. These forces challenge the small ligaments of ACL and PCL to hold our knees together and limited excessive forward and backward movement. In contrast, compressive force is determined by the amount of pressure the body is pushing on two parts. There are two areas that sustain this compressive force; 1) the meniscus as it absorbs the opposing stress between the tibia and the femur, and 2) the backside of the patella (kneecap) as pressure increases through the descent of a squat.
Science tells us that the ligaments inside our knees are under very little stress at the bottom of a squat due to the mechanics of this inverse relationship. Harmful shear forces are dramatically decreased due to an increase in compression and it seems that the deeper we squat the safer it is on the ligaments of the knee. The most well-known ligament, the ACL (Anterior Cruciate Ligament), is under little stress in the bottom of a squat. In fact the stress to the ACL during a squat is actually highest during the first four inches of the squat decent (around 15-30° of knee flexion)* and continues to decrease the deeper the descent. The lesser known ligament, the PCL (Posterior Cruciate Ligament) sustains it’s max forces just above a parallel squat (around 90° of knee flexion).
It seems that Dr. Klein’s detrimental claims of the deep squat stretching out our ligaments, ultimately leaving them unstable is but a myth that just wont die. Science has since shown repeatedly that squatting deep may have a protective effect on our knees by increasing stability. In 1986, researchers compared knee stability among powerlifters, basketball players and runners. After a heavy squat workout, the powerlifters actually had more stability in their knees than did the basketball players did. In 1989, another group of researchers were able to show that competitive weightlifters and powerlifters had knee ligaments that were less lax than those who never squatted. The prevailing research continues to show that the deep squat is a sage exercise to include in a healthy athlete’s training program.

LADDER DRILLS DO NOT INCREASE SPORT PERFORMANCE
Good luck being able to see a defender coming while you are staring at your superb footwork!
Ladder drills have become hailed as a top training tool for producing athleticism, but do the claims about creating faster feet really equal more speed and greater agility?
Ladder training typically involves following a set footwork pattern – moving the feet inside and outside the rungs of a ladder that is laid flat on the ground – where the goal becomes to increase speed while maintaining the pattern. These drills have become hailed as a top tool for producing athleticism, from youth leagues to the pros, yet the science of creating faster feet does not equal more speed or greater agility come game time. In fact, drills using speed and agility ladders under the guise of increasing on-field performance is counterproductive.
Before we dive in, let’s all agree that…
Everything done in a gym should be seen as physical preparation for sports not performed in the gym. Any attempt to correlate athletic performance to any drill is futile due to the chaotic nature of sports and the processing of multiple variables in any instant of gameplay.
For any training modality to work effectively, it has to replicate or produce similar benefits of the end goal. This means the given exercise or tool used should closely replicate the speed, force application, change of direction, as well as the metabolic and neural demands of the activity. If it doesn’t, then it will not produce the desired results.
And when it comes to youth or beginner, everything works in the trainers favor to improve all aspects of strength, endurance, quickness, etc. (However, it could be argued that doing body weight squats would have the same benefit.) Additionally, ladders can be a great tool for developing neuromuscular coordination and provide an excellent multi-planar dynamic warm-up at any sporting level.
That said, this article is aimed at addressing why ladder drills do not increase athleticism or on-field performance by improving speed and agility. It should be seen that producing speed is more than the ability to move your feet fast, just as agility is more than the proficiency of learning footwork patterns. If we think about the ground as a springboard from which we draw speed, it is not how fast you can dance over it, but how much force goes into it, and how an athlete overcomes inertia to generate a powerful movement; then we can see how ladder drills do not increase performance in your sport of choice, unless it happens to be salsa dancing. Therefore we need to have a better understanding of speed and agility:
Speed is defined by the following equation: (Stride Length x Stride Frequency) / Time. Research has shown that the fastest athletes are not faster because they take more strides, but because they cover more ground with each stride. This is possible because they put more force into the ground enabling them to cover a given distance in a shorter amount of time. It is a matter of power generation; driving the foot against the ground, enables the extensor mechanism from the hip extensors (the all-powerful glutes and hamstrings), the knee extensors (quadriceps), and the plantar flexors of the ankle to propel the body in a forward motion. When you apply greater force into the ground with a forward lean and at a horizontal angle in a smaller time, you generate more speed. As that force increases there is an inverse relationship between ground contact and distance covered. Taking steps that are more powerful than your competitor, will ultimately allow you to outrun them, at least in a straight line. An example would be how Usain Bolt can complete a 100 meter sprint with a stride count of 42, while everyone else in the field managed to 46-48; his stride length was much higher (force) but his stride frequency was about the same.
Agility is the ability to decelerate one’s momentum, stop, overcome inertia and accelerate one’s body mass in another direction in as little time as possible. Essentially, if you’re running straight forward and a defender jumps out of the bushes, you want to be able to create a powerful movement that allows you to turn or change direction in a split second. The most effective way to change direction involves having the legs move outside of vertical alignment of the center of mass, and driving them into the ground at as horizontal of an angle as possible to create a strong impulse against the pull of momentum to continue in another direction. From a physics perspective, momentum along with impulse and inertia, are critical components of agility. The ability to decelerate and stop one’s momentum in as short distance/period of time as possible requires great amount of relative unilateral strength and power, particularly in the extensor mechanism musculature of the lower extremities. Equally important, impulse can be found in the period of time where switching from eccentric action (deceleration) to concentric action (acceleration) occurs. Thus, the quicker an athlete can decelerate, overcome inertia, shift impulse momentum and propel in another direction the more agile an athlete is seen to be.
Given the above description on speed and agility it should be seen that performance is inherently predicated on the application of speed in concert with the impulse of agility. The ability to generate forward momentum/force is equally as important as being able to act and react to the chaotic unpredictability of an outside stimulus. With this understanding of performance we can see that any drill that is directed toward constricting an athlete to tip-toe through a series of 15 x 15 inch boxes without posing a challenge to displacement of an athlete’s center of mass or an effort in creating forward momentum through the development of proper mechanics will only serve as a deterrent to the claims of improving performance.
There is very little to gain with the incorporation of ladder drills, as such drills are merely displays of an already present athleticism. Natural athletes learn skills quickly and replicate movement efficiently within a very short period. Within a few weeks of practicing with a ladder, an athlete can become very proficient in the drill, yet when it comes to performing in the game there is very little transfer. Why? Because ladder drills are learned patterns without the influence of an outside stimulus, like a ball or a defender coming at you, and all the hours and effort spent learning how to tip-toe properly while staring at the ground is only working against the athlete who needs to see and react. When athletes who use these drills as a main focus are required to respond in a chaotic environment like a game, their own muscle memory could work against them—tip-toeing gracefully around a defender instead of creating a quick and powerful movement, only to get blasted by a guy the athlete didn’t see because they’ve been trained to staring at the ground. Simply put, fast feet do nothing if you don’t go anywhere. Getting better at predetermined movement patterns is not indication of on-field performance as there is very little transfer from a learned movement to a chaotic gametime environment. In the end, there is no way to practice the perfect pattern for football, soccer, hockey, ultimate frisbee, or any other sport for that matter. It is a requirement to react powerfully and quickly, and there certainly isn’t any benefit to staring at the ground.
Instead of wasting precious time on ladder drills, a strong focus on strength and power development with emphasis on both bilateral and unilateral movements are the best approach, not only for performance but injury prevention as well. An example would be the following:
Bilateral Strength – Squats and Deadlift variations
Bilateral Power – Olympic lifts, Box Jumps and Depth Jumps
Unilateral Strength – Split Squat variations and Step-Ups
Unilateral Power – Olympic lifts, Sprints and Penta-Hops
Thinking of the springboard example used earlier, the ground is where we draw speed, how much force we apply to it is the amount of speed we are going to get out of it. Elite-level sprinters can produce over 360 pounds of force per leg when moving at top speed. Good luck tip-toeing your way to those numbers. Force into the ground equals forward motion, this is because speed is a matter of force production and being agile is the ability to react, absorb and overcome inertia, therefore the ability to maintain strength and generate power is the real solution to generating more speed and creating better agility. Once an athlete has corrected any structural imbalances, increased relative strength and reactive/ballistic ability, then and only then is it acceptable to place emphasis on drills utilizing the ladder. However it is important to remember that no drill is a better substitute than having the athlete play their specific sport, as the ladder will never juke one way or try to cross you over.

Fixing the Flaws: A Look at the Ten Most Common Biomechanical Weak Links in Athletes
Written on January 31, 2008, by Eric Cressey
Even the best athletes are limited by their most significant weaknesses. For some athletes, weaknesses may be mental barriers along the lines of fear of playing in front of large crowds, or getting too fired up before a big contest. Others may find that the chink in their armor rests with some sport-specific technique, such as shooting free throws. While these two realms can best be handled by the athletes’ head coaches and are therefore largely outside of the control of a strength and conditioning coach, there are several categories of weak links over which a strength and conditioning specialist can have profound impacts. These impacts can favorably influence athletes’ performance while reducing the risk of injury. With that in mind, what follows is far from an exhaustive list of the weaknesses that strength and conditioning professionals may observe, especially given the wide variety of sports one encounters and the fact that the list does not delve into neural, hormonal, or metabolic factors. Nonetheless, in my experience, these are the ten most common biomechanical weak links in athletes:
1. Poor Frontal Plane Stability at the Hips: Frontal plane stability in the lower body is dependent on the interaction of several muscle groups, most notably the three gluteals, tensor fascia latae (TFL), adductors, and quadratus lumborum (QL). This weakness is particularly evident when an athlete performs a single-leg excursion and the knee falls excessively inward or (less commonly) outward. Generally speaking, weakness of the hip abductors – most notably the gluteus medius and minimus – is the primary culprit when it comes to the knee falling medially, as the adductors, QL, and TFL tend to be overactive. However, lateral deviation of the femur and knee is quite common in skating athletes, as they tend to be very abductor dominant and more susceptible to adductor strains as a result. In both cases, closed-chain exercises to stress the hip abductors or adductors are warranted; in other words, keep your athletes off those sissy obstetrician machines, as they lead to a host of dysfunction that’s far worse that the weakness the athlete already demonstrates! For the abductors, I prefer mini-band sidesteps and body weight box squats with the mini-band wrapped around the knees. For the adductors, you’ll have a hard time topping lunges to different angles, sumo deadlifts, wide-stance pull-throughs, and Bulgarian squats.
2. Weak Posterior Chain: Big, fluffy bodybuilder quads might be all well and good if you’re into getting all oiled up and “competing” in posing trunks, but the fact of the matter is that the quadriceps take a back seat to the posterior chain (hip and lumbar extensors) when it comes to athletic performance. Compared to the quads, the glutes and hamstrings are more powerful muscles with a higher proportion of fast-twitch fibers. Nonetheless, I’m constantly amazed at how many coaches and athletes fail to tap into this strength and power potential; they seem perfectly content with just banging away with quad-dominant squats, all the while reinforcing muscular imbalances at both the knee and hip joints. The muscles of the posterior chain are not only capable of significantly improving an athlete’s performance, but also of decelerating knee and hip flexion. You mustn’t look any further than a coaches’ athletes’ history of hamstring and hip flexor strains, non-contact knee injuries, and chronic lower back pain to recognize that he probably doesn’t appreciate the value of posterior chain training. Or, he may appreciate it, but have no idea how to integrate it optimally. The best remedies for this problem are deadlift variations, Olympic lifts, good mornings, glute-ham raises, reverse hypers, back extensions, and hip-dominant lunges and step-ups. Some quad work is still important, as these muscles aren’t completely “all show and no go,” but considering most athletes are quad-dominant in the first place, you can usually devote at least 75% of your lower body training to the aforementioned exercises (including Olympic lifts and single-leg work, which have appreciable overlap).
Regarding the optimal integration of posterior chain work, I’m referring to the fact that many athletes have altered firing patterns within the posterior chain due to lower crossed syndrome. In this scenario, the hip flexors are overactive and therefore reciprocally inhibit the gluteus maximus. Without contribution of the gluteus maximus to hip extension, the hamstrings and lumbar erector spinae muscles must work overtime (synergistic dominance). There is marked anterior tilt of the pelvis and an accentuated lordotic curve at the lumbar spine. Moreover, the rectus abdominus is inhibited by the overactive erector spinae. With the gluteus maximus and rectus abdominus both at a mechanical disadvantage, one cannot optimally posteriorly tilt the pelvis (important to the completion of hip extension), so there is lumbar extension to compensate for a lack of complete hip extension. You can see this quite commonly in those who hit sticking points in their deadlifts at lockout and simply lean back to lock out the weight instead of pushing the hips forward simultaneously. Rather than firing in the order hams-glutes- contralateral erectors-ipsilateral erectors, athletes will simply jump right over the glutes in cases of lower crossed syndrome. Corrective strategies should focus on glute activation, rectus abdominus strengthening, and flexibility work for the hip flexors, hamstrings, and lumbar erector spinae.
3. Lack of Overall Core Development: If you think I’m referring to how many sit-ups an athlete can do, you should give up on the field of performance enhancement and take up Candyland. The “core” essentially consists of the interaction among all the muscles between your shoulders and your knees; if one muscle isn’t doing its job, force cannot be efficiently transferred from the lower to the upper body (and vice versa). In addition to “indirectly” hammering on the core musculature with the traditional compound, multi-joint lifts, it’s ideal to also include specific weighted movements for trunk rotation (e.g. Russian twists, cable woodchops, sledgehammer work), flexion (e.g. pulldown abs, Janda sit-ups, ab wheel/bar rollouts), lateral flexion (e.g. barbell and dumbbell side bends, overhead dumbbell side bends), stabilization (e.g. weighted prone and side bridges, heavy barbell walkouts), and hip flexion (e.g. hanging leg raises, dragon flags). Most athletes have deficiencies in strength and/or flexibility in one or more of these specific realms of core development; these deficiencies lead to compensation further up or down the kinetic chain, inefficient movement, and potentially injury.
4. Unilateral Discrepancies: These discrepancies are highly prevalent in sports where athletes are repetitively utilizing musculature on one side but not on the contralateral side; obvious examples include throwing and kicking sports, but you might even be surprised to find these issues in seemingly “symmetrical” sports such as swimming (breathing on one side only) and powerlifting (not varying the pronated/supinated positions when using an alternate grip on deadlifts). Obviously, excessive reliance on a single movement without any attention to the counter-movement is a significant predisposition to strength discrepancies and, in turn, injuries. While it’s not a great idea from an efficiency or motor learning standpoint to attempt to exactly oppose the movement in question (e.g. having a pitcher throw with his non-dominant arm), coaches can make specific programming adjustments based on their knowledge of sport-specific biomechanics. For instance, in the aforementioned baseball pitcher example, one would be wise to implement extra work for the non-throwing arm as well as additional volume on single-leg exercises where the regular plant-leg is the limb doing the excursion (i.e. right-handed pitchers who normally land on their left foot would be lunging onto their right foot). Obviously, these modifications are just the tip of the iceberg, but simply watching the motion and “thinking in reverse” with your programming can do wonders for athletes with unilateral discrepancies.
5. Weak Grip: – Grip strength encompasses pinch, crushing, and supportive grip and, to some extent, wrist strength; each sport will have its own unique gripping demands. It’s important to assess these needs before randomly prescribing grip-specific exercises, as there’s very little overlap among the three types of grip. For instance, as a powerlifter, I have significantly developed my crushing and supportive grip not only for deadlifts, but also for some favorable effects on my squat and bench press. Conversely, I rarely train my pinch grip, as it’s not all that important to the demands on my sport. A strong grip is the key to transferring power from the lower body, core, torso, and limbs to implements such as rackets and hockey sticks, as well as grappling maneuvers and holds in mixed martial arts. The beauty of grip training is that it allows you to improve performance while having a lot of fun; training the grip lends itself nicely to non-traditional, improvisational exercises. Score some raw materials from a Home Depot, construction site, junkyard, or quarry, and you’ve got dozens of exercises with hundreds of variations to improve the three realms of grip strength. Three outstanding resources for grip training information are Mastery of Hand Strength by John Brookfield, Grip Training for Strength and Power Sports by accomplished Strongman John Sullivan, and www.DieselCrew.com.
6. Weak Vastus Medialis Oblique (VMO): The VMO is important not only in contributing to knee extension (specifically, terminal knee extension), but also enhancing stability via its role in preventing excessive lateral tracking of the patella. The vast majority of patellar tracking problems are related to tight iliotibial bands and lateral retinaculum and a weak VMO. While considerable research has been devoted to finding a good “isolation” exercise for the VMO (at the expense of the overactive vastus lateralis), there has been little success on this front. However, anecdotally, many performance enhancement coaches have found that performing squats through a full range of motion will enhance knee stability, potentially through contributions from the VMO related to the position of greater knee flexion and increased involvement of the adductor magnus, a hip extensor (you can read a more detailed analysis from me here. Increased activation of the posterior chain may also be a contributing factor to this reduction in knee pain, as stronger hip musculature can take some of the load off of the knee stabilizers. As such, I make a point of including a significant amount of full range of motion squats and single-leg closed chain exercises (e.g. lunges, step-ups) year-round, and prioritize these movements even more in the early off-season for athletes (e.g. runners, hockey players) who do not get a large amount of knee-flexion in the closed-chain position in their regular sport participation.
7 & 8. Weak Rotator Cuff and/or Scapular Stabilizers: I group these two together simply because they are intimately related in terms of shoulder health and performance.
Although each of the four muscles of the rotator cuff contributes to humeral motion, their primary function is stabilization of the humeral head in the glenoid fossa of the scapula during this humeral motion. Ligaments provide the static restraints to excessive movement, while the rotator cuff provides the dynamic restraint. It’s important to note, however, that even if your rotator cuff is completely healthy and functioning optimally, you may experience scapular dyskinesis, shoulder, upper back, and neck problems because of inadequate strength and poor tonus of the muscles that stabilize the scapula. After all, how can the rotator cuff be effective at stabilizing the humeral head when its foundation (the scapula) isn’t stable itself? Therefore, if you’re looking to eliminate weak links at the shoulder girdle, your best bet is to perform both rotator cuff and scapular stabilizer specific work. In my experience, the ideal means of ensuring long-term rotator cuff health is to incorporate two external rotation movements per week to strengthen the infraspinatus and teres minor (and the posterior deltoid, another external rotator that isn’t a part of the rotator cuff). On one movement, the humerus should be abducted (e.g. elbow supported DB external rotations, Cuban presses) and on the other, the humerus should be adducted (e.g. low pulley external rotations, side-lying external rotations). Granted, these movements are quite basic, but they’ll do the job if injury prevention is all you seek. Then again, I like to integrate the movements into more complex schemes (some of which are based on PNF patterns) to keep things interesting and get a little more sport-specific by involving more of the kinetic chain (i.e. leg, hip, and trunk movement). On this front, reverse cable crossovers (single-arm, usually) and dumbbell swings are good choices. Lastly, for some individuals, direct internal rotation training for the subscapularis is warranted, as it’s a commonly injured muscle in bench press fanatics. Over time, the subscapularis will often become dormant – and therefore less effective as a stabilizer of the humeral head – due to all the abuse it takes.
For the scapular stabilizers, most individuals fall into the classic anteriorly tilted, winged scapulae posture (hunchback); this is commonly seen with the rounded shoulders that result from having tight internal rotators and weak external rotators. To correct the hunchback look, you need to do extra work for the scapular retractors and depressors; good choices include horizontal pulling variations (especially seated rows) and prone middle and lower trap raises. The serratus anterior is also a very important muscle in facilitating scapular posterior tilt, a must for healthy overhead humeral activity. Supine and standing single-arm dumbbell protractions are good bets for dynamically training this small yet important muscle; scap pushups, scap dips, and scap pullups in which the athlete is instructed to keep the scapulae tight to the rib cage are effective isometric challenges to the serratus anterior.
Concurrently, athletes with the classic postural problems should focus on loosening up the levator scapulae, upper traps, pecs, lats, and anterior delts. One must also consider if these postural distortions are compensatory for kinetic chain dysfunction at the lumbar spine, pelvis, or lower extremities. My colleague Mike Robertson and I have written extensively on this topic here. Keep in mind that all of this advice won’t make a bit of difference if you have terrible posture throughout the day, so pay as much attention to what you do outside the weight room as you do to what goes on inside it.
9. Weak Dorsiflexors: It’s extremely common for athletes to perform all their movements with externally rotated feet. This positioning is a means of compensating for a lack of dorsiflexion range of motion – usually due to tight plantarflexors – during closed-chain knee flexion movements. In addition to flexibility initiatives for the calves, one should incorporate specific work for the dorsiflexors; this work may include seated dumbbell dorsiflexions, DARD work, and single-leg standing barbell dorsiflexions. These exercises will improve dynamic postural stability at the ankle joint and reduce the risk of overuse conditions such as shin splints and plantar fasciitis.
10. Weak Neck Musculature: The neck is especially important in contact sports such as football and rugby, where neck strength in all planes is highly valuable in preventing injuries that may result from collisions and violent jerking of the neck. Neck harnesses, manual resistance, and even four-way neck machines are all good bets along these lines, as training the neck can be somewhat awkward. From a postural standpoint, specific work for the neck flexors is an effective means of correcting forward head posture when paired with stretches for the levator scapulae and upper traps as well as specific interventions to reduce postural abnormalities at the scapulae, humeri, and thoracic spine. In this regard, unweighted chin tucks for high reps throughout the day are all that one really needs. This is a small training price to pay when you consider that forward head posture has been linked with chronic headaches.
Closing Thoughts
A good coach recognizes that although the goals of improving performance and reducing the risk of injury are always the same, there are always different means to these ends. In my experience, one or more of the aforementioned ten biomechanical weak links is present in almost all athletes you encounter. Identifying biomechanical weak links is an important prerequisite to choosing one’s means to these ends. This information warrants consideration alongside neural, hormonal, and metabolic factors as one designs a comprehensive program that is suited to each athlete’s unique needs.
Pearls of Wisdom
Pearls of Training Wisdom from Ed Coan, Charles R. Poliquin and Matt Wenning
Bench Press
Correct Grip Width
Grip width is a function of your biomechanics and needs to be set according to this. Biomechanics change from athlete to athlete due to shoulder width, length of the humerus and length of the forearms. A simple way to figure this out is to go into your natural push-up position, the body automatically selects the grip width you’re the strongest in and feels the best. That’s your competitive bench press grip. Just because you´re allowed to grip wider doesn´t mean it’s good for you.
Bench More with Structural Balance
Train your rotator cuff muscles and scapular retractors for a big bench and healthy shoulders. How are you supposed to bench big weights if you can´t even stabilize them? That’s like putting a Lamborghini engine into a Civic while still relying on the Civic’s breaking system. You´re just begging for an injury.
Drive your head into the bench on the concentric phase of the lift
This activates your neck extensors and puts another 2-7 kg on your bench. Strong neck extensors potentiate every upper body lift.
Squat
Always keep your Sternum high
And pick a spot somewhere in front of you that’s slightly above to look at. This ensures that your head is high at all times. Your eyes dictate where the body goes. Look down and you’ll round forward.
Warm up your weak and/or inactive muscles before you train
Pick 3 exercises to address them and try to get those muscles working. Don’t smash yourself on the warm up, just potentiate those muscles. If you sit on your ass the whole day your glutes are most likely inactive and the lower back will take over a large portion of the work. I´m sure you experienced this at some point: your lower back is completely fatigued after squatting. That’s because your glutes are not firing.
60-70% of your total training volume should be traction based exercises for your spine
Heavy squatting and deadlifting always compress your spine so make sure you decompress it when doing your accessory work for more longevity.
Deadlift
The deadlift has a disadvantage to the bench press and the squat
This is because there´s no eccentric movement preceding the concentric phase. In the other two lifts it´s possible to correct your form on the way down but with deadlifts you can’t. That’s why the starting position is most important.
Deadlift cycles are the shortest due to their demand on the nervous system
Stretch your hip flexors statically before deadlifting
This will put another 5-15 kg on your deadlift. Tight hip flexors inhibit the strength of your hip extensors.
Endurance vs. Conditioning
The statement is simple – Endurance is the most overrated of all sports specific qualities. Why Because endurance is neither necessary nor the limiting factor in most sports. Conditioning is. Where is the difference?
Definition of Endurance and Conditioning as follows:
Endurance is the ability to maintain a certain effort with minimal fatigue – A classic example is a marathon. At a marathon it´s crucial to run 2+ h in one go with minimal fatigue.
Conditioning is the ability to repeat a certain effort with minimal fatigue – Classic examples are team sports like Soccer, American Football, Basketball and Ice hockey. In those sports it is crucial to keep fatigue between the first and the last sprint (and all the others in between) as minimal as possible.
Most Olympic, Team- and Combat Sports are cyclical, that means certain efforts must be repeated. A 100m sprinter has to repeat his performance in heats, semi-finals and finals. A thrower has 6 attempts per competition and an olympic weightlifter has 3 per discipline. If the performance decreases too much from attempt to attempt then his conditioning is the limiting factor.
A more extensive example is soccer. Depending on the position of a player he runs about 8-12km per game. From which he runs 400-1200m above 85% of his top speed. The remaining 8-10km are walking, trotting and hardly relevant for the game.
These 400-1200m are crucial. The average sprinting distance is about 17m. Sprints over 30m, thats the distance between mid- and penalty line, are very rare.
The critical distance is 0-5 m. That´s the famous “one step faster”. Based on player statistics of the English Premier League, players with the highest salary, regardless of their position have one thing in common, they are the fastest over 0-5m.
At an average sprinting distance of about 17m and a game-relevant total distance of 400-1200m those are about 24 to 70 sprints per game. Assuming a uniform load density, it is a load of 2-3 seconds followed by a 1:20-4:00 minute break. I sprints are repeated with minimal rest its more than 3 in a row before the ball is out of sight.
So what is critical for a game in this case in terms of physical qualities?
Endurance or Conditioning?
Critical are those 24 to 70 sprints in under 90 minutes game time and their repetition with minimal fatigue, not endurance. Endurance isn´t relevant in soccer because of the short bursts of sprints they do.
To run 10-60 minutes at once has very poor correlation with the ability to repeat 24 to 70 sprints in 90 minutes with minimal fatigue.
2 FORMS OF ENDURANCE
Endurance at high intensity – that is the ability to maintain a stress of high intensity upright with minimal fatigue. A good example is a 100m sprinter. A sprinter reaches his top speed after 60-70m. From 60-70m the critical factor becomes maintaining the top speed as long as possible without getting tired. In this case we speak of speed endurance. Usain Bolt is a great example for this. His greatest advantage over his opponents, and the reason why he is even more dominant over 200m than over 100m, is his exceptional speed endurance, the ability to maintain his top speed with minimal fatigue and leave all his opponents behind after 60-70m.
Endurance at low intensity – that is the ability to maintain a stress of low intensity upright with minimal fatigue. A good example is the marathon. In a marathon it´s crucial to maintain a performance for 2+ h with minimal fatigue. In one go and without interruptions.
Intensity – definition: Intensity is the load of a performance in relation to the maximal performance. A performance at high intensity for example is a sprint over 50 meters at maximum speed or BB Back Squats for 3 reps with 90 % of 1RM. In contrast to this, a performance of low intensity is a run over 10000m at maximum speed or squats for 25 reps with 50 % of 1RM. That means intensity is not defined on the subjective level of effort but correlates performance with maximum power/effort.
Both forms of endurance, especially the last one, are not relevant in most Olympic-, Team- and Combat Sports because the duration of the load in those sports is far lower.
In most Olympic-, Team- and Combat sports conditioning is critical. The ability to repeat a performance with minimal fatigue.
2 FORMS OF CONDITIONING
Conditioning at high volume – the ability to repeat a certain performance very often with minimal fatigue. The best example is soccer, where depending on the position of the player the average sprinting distance has to be repeated up to 70 times per game with minimal fatigue.
Conditioning at low volume – the ability to repeat a certain performance a few times with minimal fatigue. Best example is Olympic Weightlifting. There you only have to repeat an attempt 3 times per discipline and competition – so 3 Reps of the Snatch and 3 Reps of the Clean & Jerk, thats it.
The lower the volume, the more critical becomes the performance during the attempt itself. It is not that crucial to repeat that performance often.
The higher the volume, the more critical is the ability to repeat it. Therefore in weightlifting the ability to repeat a performance is less important than the absolute performance, namely to move maximal weight. In comparison with weightlifting soccer players need lower maximal- and explosive strength level than weightlifters – but higher levels of conditioning. As the ability to repeat maximal Sprinting Speed for the 90 minute game is critical.
TRAINING ENDURANCE VS. CONDITIONING
The training for Endurance and Conditioning is obviously very different.
The Training of Endurance basically includes a higher volume of total work, a lower -if any – number and duration of breaks and lower average intensity of effort. While the training of conditioning basically comprises a lower total volume of work and an increased number and duration of breaks at higher average intensity of effort.
51 rounds divided into 3 blocks á (9 rounds, 3 minutes pause, 5 rounds, 3 minutes pause, 3 rounds) with 10 minute pauses between the blocks. The rounds have to be executed with minimal 85% of world record time.
That´s a solution for a 1500m short track speed skater whose limiting factor is endurance over 1500m. That means he fatigues too much in the last 3-5 rounds of the 1500m race which is 14,5 rounds.
This is a program written by the legendary short track speed skating Coach Yves Nadeau, whose athletes won 204 medals at World Championchips and the Olympic Games since 1983.
Sample training program for Conditioning in Soccer
This is a modified strongman medley used to condition a soccer player
A1 Forward Sleddrag, 20m, 5s rest
A2 Prowler Push, High Handle, elbows extended, 20m, 5s rest
A3 Sprint, 20m, 120s rest
Repeat 4-10 times depending on the current Conditioning Level of the Athletes
This is a solution for a player or a team whose physically limiting factor is fatigue in the latter part of the game.
The ability to repeat multiple blocks of three 20m efforts with minimal rest has clearly a higher correlation to soccer-specific performance than 10-60min straight jogging. To train the sprinting power, speed and conditioning at the same time a combination of strength- and condititoning training in the weightroom can also be utilized. To see how it looks in detail, here is an example of a squat training program for conditioning in Ju Jitsu.
Sample training program for Conditioning in Ju Jitsu
12 sets of 4 reps of BB Back Squats with a 30X0 tempo and 60s rest.
From workout to workout increase the average- and maximal weight used.
That´s a solution for a fighter whose physical limiting factor is fatiguing from effort to effort. The higher intensity and resistance on the squats allow for training conditioning and power of a single action at the same time.
This is the program used for preparation of YPSI Athlete Romy Korn for the Ju Jitsu World Championship 2014 in Paris where she became World Champion in the 70+ kg weightclass at a bodyweight of 71,2kg with all her opponents outweighing her by 15+kg.
Conclusion: For a coach it is crucial to identify whether endurance and/or conditioning are necessary for a certain sports and disciplines. And to assess which the limiting factor of the individual athlete is. So the training program can be specifically tailored to the needs of the individual sport and the limiting factor of the individual athlete. To maximise the efficiency of training and therefore increase pPerformance on the field, court, ice or mat.
Hamstrings Development
The evidence is mounting that a range of exercises are necessary, if athletes want to achieve complete hamstrings development.
This new study shows that 4 different exercises produced very different responses in each of the 4 hamstrings muscles and 3 main regions (proximal, middle, and distal) when measured using MRI from pre- to post-exercise.
This suggests that both hip extension exercises (e.g. Russian belt deadlift and hip extension conic pulley, as in this study) as well as knee flexion exercises (e.g. Nordic curl and flywheel leg curl, as in this study) are necessary to achieve increases in muscular strength and size of all hamstrings muscles and regions.
Smart Abdominal Training
Although you are regularly bombarded with exercises claiming to tone and strengthen the abdominal muscles, many of these exercises are inadequate and ineffective. Some exercises may actually lead to lower back pain, and do little to strengthen the abdominals.
The ‘villains’ of abdominal training are the hip flexors, which bring the legs and trunk toward each other. Muscles that flex the hip include the psoas major, illiacus, rectus femoris, pectineus and sartorius. Full sit-ups involve the hip flexors, which may cause the lower back to arch and unwanted back pain, particularly in individuals with relatively weak abdominals. Leg-raising exercises in a supine position challenge the hip flexors with limited involvement of the abdominals. Frequently, there is a muscle imbalance between the weaker abdominals and the stronger hip flexors in trunk flexing movements. The goal of abdominal training is to maximize the involvement of the abdominals, while minimizing the involvement of the hip flexors.
Importance of Structural Balance for Injury Prevention
What is the Science Behind Structural Balance Assessments?
The concept of structural balance is that a muscle’s ability to develop force is a function of the strength of the opposing muscle group and its stabilizers. Many training and sports-related injuries are often the result of muscular imbalances – strength discrepancies between opposing and synergist muscle groups or even between limbs. These structural imbalances are often caused by a combination of the repetitive motions involved in many sports and/or a lack of exercise variety in training.
A Structural Balance Analogy:
Another way to understand structural balance to imagine you are building a house. In construction, the term “footing” describes the concrete support that the foundation is built upon. The footing also spreads the weight of the structure evenly over a wider area. The walls of the house are then built on the foundation. However, if the footing is poorly developed it compromises the stability of the foundation, which in turn, compromises the structural integrity of the entire house.
Each of the body’s joints are similar to the above analogy in that the joint is the house and the muscles and tendons controlling that joint are the foundation and footing. Viewed as a whole, if the stability of one joint is compromised it will affect the structural integrity of the entire body.
This is the proverbial “only as strong as the weakest link” axiom.
A joint is controlled by two primary sets of opposing muscle groups; one set of muscles flexes the joint and the other extends it. Synergistic muscles help the respective primary muscle perform its action. While one primary muscle group and its synergists are moving the joint, the opposing muscle group and it synergists are stabilizing it from the opposite side.
There is an optimal balance of strength between these muscle groups that control a joint, but if the muscles on one side of the joint are disproportionately stronger than the muscles on the opposing side it creates joint instability, which increases the risk of injury to that joint.
The take away point here is balance is important and vital to injury prevention.
Figure 1: Notice the difference between normal and imbalanced strength and its impact on a joint.
When the central nervous system senses joint instability, it reduces the ability to continue strengthening the muscles that are already too strong. This an effective safety mechanism the body utilizes to protect itself from injury.
However, this safety mechanism can be “overridden” by attempting to force the already too strong muscles to get even stronger — many injuries occur under these conditions. If you place more strain on the weakest link than it can tolerate, the chain breaks.
While unpredictable accidents will still occur, a thorough structural balance assessment can:
- Identify muscle weaknesses that leave a joint vulnerable to injury and compromise performance;
- Faulty movement patterns that cause misalignment of the body, which results in distorted movement;
- Muscle tightness that can result in strained or torn muscles, and;
- Provide the blueprint from which your initial training program is developed.
A structural balance assessment also provides a starting point for your training. Your initial training program is developed based on the results of your assessment and aimed at correcting your weaknesses, faulty movement patterns, and tight muscles through a progression of corrective and remedial exercises. This approach expedites your results and helps ensure continuous progress.
A thorough structural assessment should be the first step of anyone’s training program whether you are a competitive athlete from any level of competition, an avid CrossFitter, or someone who wants to look better and improve your health.
Excerpt from Athletic Strength Institute
Stuart McGill on Abdominal Training
The science of spine stability: Effective spine stabilization approaches must begin with a solid understanding of what stability is. From a spine perspective it has little to do with the ability to balance on a gym ball. This is simply the ability to maintain the body in balance which is important but does not address the unstable spine. In fact, in many instances the unstable spine is also flexion intolerant and with associated intolerance to compression. Sitting on an exercise ball performing movement exercises increases spine compression to a flexed spine. This retards progress – it is generally a poor choice of back exercise until quite late in a therapeutic progression. True spine stability is achieved with a “balanced” stiffening from the entire musculature including the rectus abdominis and the abdominal wall, quadratus lumborum, latissimus dorsi and the back extensors of longissimus, ilioicostalis and multifidus. Focusing on a single muscle generally does not enhance stability but creates patterns that when quantified result in less stability. It is impossible to train muscles such as transverse abdominis or multifidus in isolation – people cannot activate just these muscles. Do not perform abdominal hollowing techniques as it reduces the potential energy of the column causing it to fail at lower applied loads (McGill, 2009). Interestingly a recent clinical trial (Koumantakis et al, 2005) compared the efficacy of many of the exercises that I quantified and published in Physical Therapy (McGill 1998), with the same exercises combined with specific transverse abdominis isolation (hollowing etc.). Adding the specific transverse abdominis training reduced efficacy! Instead, the abdominal brace (contracting all abdominal muscles) enhances stability. Target contraction levels for bracing and training techniques are described in McGill (2006). Finally, some provocative tests, such as a shear test, will help reveal which classification of patient is best suited for a stabilization approach (Hicks et al, 2005).
Linking Anatomy with Function: Consider the usual and popular approach to train the abdominal wall muscles by performing situps or curl-ups over a gym ball for example. But consider the rectus abdominis where the contractile components are interrupted with transverse tendons giving the “six pack” look. The muscle is not designed for optimal length change but rather to function as a spring. Why have these transverse tendons in rectus abdominis? The reason is that when the abdominals contract, “hoop stresses” are formed by the oblique muscles that would split the rectus apart. In addition to the spring-like architecture of the muscle consider how it is used. People rarely flex the rib cage to the pelvis shortening the rectus in sport or everyday activity. Rather they stiffen the wall and load the hips or shoulders – if this is performed rapidly such as in a throw or movement direction change, the rectus functions as an elastic storage and recovery device. When lifting weights it stiffens to efficiently transmit the power generated at the hips through the torso. Those individuals who do actively flex the torso (think of cricket bowlers and gymnasts) are the ones who suffer with high rates of disc damage and pain. Now revisit the common training approach of curling the torso over a gym ball that replicates the injury mechanics while not creating the athleticism that enhances performance. This is a rather poor choice of exercise for most situations. Yet many clients will expect that a gymball be used. Play a trick on these clients and retain the gymball but change the exercise from a spine breaking curlup to a plank where the elbows are placed on the ball. Now “stir the pot” to enhance the spring and spare the spine – this is a much superior exercise for most people.
gluteal muscle activation retraining based primarily on the original work of Professor Janda has been honed in our own lab (see figure 4). This cannot be accomplished with traditional squat training (McGill, 2007). Chronic back pain tends to cause hip extension using the hamstrings and subsequent back extension using the spine extensors creating unnecessary crushing loads. Gluteal muscle reintegration helps to unload the back.
Finally consider exercises such as the squat. Interestingly when we measure world class strongmen carrying weight, NFL footballers running planting the foot and cutting – neither of these are trained by the squat. This is because these exercises do not train the quadratus lumborum and abdominal obliques which are so necessary for these tasks. In contrast, spending less time under a bar squatting and redirecting some of this activity with asymmetric carries such as the farmers walk (or bottoms-up kettlebell carry – see figure 7) builds the athleticism needed for higher performance in these activities in a much more “spine friendly” way. The core is never a power generator as measuring the great athletes always shows that the power is generated in the hips and transmitted through the stiffened core. They use the torso muscles as anti-motion controllers, rarely motion generators (of course there are exceptions for throwers etc but the ones who create force pulses with larger deviations in spine posture are the ones who injure first). Many more progressions to enhance athleticism in a spine sparing way are provided in my text “Ultimate back fitness and performance”
A comment on Flat Feet:
When the arches of the feet collapse, a lot of bad things happen. First, consider that the arch of the foot is supposed to flex and absorb shock. If the arch is flat, the foot lacks shock absorbency, and stress is transferred to the knees, hips, and lower back. This is why many of the advertisements for orthotics claim that they can resolve back pain.
With fallen arches, the bones of the ankle are not optimally aligned with the foot, increasing the risk of ankle injuries. According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases, approximately one million people in the US are treated for ankle injuries every year. It’s also estimated that athletes who injure an ankle are five times more likely to injure that ankle again.
Fallen arches also cause the bones of both the upper legs and lower legs to internally rotate. This rotation increases stress on the ACL. The ACL is a ligament that connects the upper and lower leg bones and provides stability to the knee, making the ACL critical for dynamic movements. Approximately 300,000 ACL injuries occur annually in the US, and the risk of injury is greater to athletes and women. Also consider that only 30 percent of ACL injuries are a result of direct contact, which suggests that an important step to preventing ACL injuries is to address the structure and function of the foot.
Another consequence of fallen arches is that the inward rotation of the upper legs increases the arch in the lower back, a condition technically referred to as lumbar hyperlordosis. Lumber hyperlordosis reduces the ability of the spine to absorb shock. The result is an increased risk of back injury and pain.
The most common method of correcting flat feet is orthotics. Orthotics don’t permanently correct fallen arches – they only work while the user is wearing them. Also, the pressure of the orthotic on the arch can also cause the arch to become weaker.
Solutions include corrective exercises to strengthen muscles that support the arch. One such muscle is the extensor hallucis longus, which creates lateral tension on the foot and also strengthens and stretches the two major calf muscles (gastrocnemius and soleus).
Simpleton Guide to Poliquin Training
Part I
Sometimes, when I'm talking to Coach Poliquin about training methodologies, muscle fiber ratios, and all the assorted high-tech, laboratory aspects of weight training, my eyes start to glaze over?not because I'm bored or anything?but because he has lost me; lost me as surely as if he had driven me out to the desert in the back of his four-wheel-drive Jeep of knowledge, kicked me out naked into the midst of scorpions, rattlers, and cacti without so much as a bottle of Evian water, and left me to flounder out under the searing sun where I start to slowly bake and fricassee.
He'll continue expounding on the intricacies of what he knows better than any one alive, and I'll find myself playing little games to make him think we're still sharing the same planet: "Yes Charles, yes, it's so clear?why didn't I see it before?" Meanwhile, I'm staring at his nose, or fantasizing about that blonde I saw on the beach the other day, the one with that metallic thong that split her declivities so deftly in two as she bounded toward the surf, her bottom as brown as a berry and just as juicy... "Yes Charles, yes, don't stop, don't stop!"
Don't get me wrong; I'm not exactly a lightweight when it comes to the science of weight training. I've read more than my share of studies, articles, and books, in addition to having years and years of practical experience. And, I've played Sherman to Charles Poliquin's Peabody for practically longer than anyone else. I'm sort of a Poliquin clone; a juvenile, ill-formed, way-down-on-the-evolutionary-scale clone, but a clone nonetheless. Still, I'll never know everything Charles knows, regardless of how much I tag along with him like some sort of loyal hound dog.
The point of all this is that I can now formulate my own, Poliquin-esque workout routines without too much wailing and gnashing of teeth. What I've done is taken seven of his principles and committed them to memory, so much so that I can't do a single exercise without taking them into consideration. It's kind of like that best-selling business book, Seven Habits of Highly Effective People, but instead, I prefer the less elegant, more humble title, "A Simpleton's Guide to Charles Poliquin's Training Principles".
If you learn these seven principles and apply them to your workout routines, you'll have the next best thing to getting Charles to design your own, individualized programs. What's more, you'll more than likely experience more progress in your training in a short period than you have in the previous five years. Here, in a nutshell, are the seven principles I've adopted (I also gave them my own descriptive names):
The Borg Principle
Anybody who's ever watched the newer versions of "Star Trek" knows about the Borg. They're the bad-ass creatures who can't be beaten using conventional methods. Blast them or their ship with phasers, and they adapt. The only way to keep them off balance is to set your weapons on a constantly shifting frequency so they can't adapt.
Well, your body is the Borg. It's designed to adapt. When you keep doing the same exercises in the same order, for the same amount of reps, using the same hand grip or foot stance, the body adapts. In effect, the nervous system becomes ""hardwired" to that particular routine and consequently, fewer muscle fibers are recruited, less energy is used, and fewer demands in general are made on the body. You become an expert at that routine, and after a surprisingly short time, you stop making progress.
If, however, you keep shaking things up, "changing the frequency," so to speak, the nervous system does not adapt. Instead, what happens is that the body?the muscles?grow stronger and bigger to survive the onslaught of your attack. Research (by Poliquin and others) shows that, in most cases, the body begins to adapt after having performed a particular routine 6 times. After that, it's time to shake things up again.
Yes, to the Borg, resistance if futile, but in weight training, resistance to becoming stale is mandatory.
The Principle of Shifting Rep Ranges
Most trainers are hopelessly mired in the old 8-10 rep range scheme. It's as automatic for them as putting two spoonfuls of sugar in their morning coffee; getting a monthly haircut from Rudy, the gay stylist; or watching Dawson's Creek on Tuesdays and wondering what that Joey chick is going to look like when she gets a little bit older. It's largely habit. True, there's a lot of evidence that doing midrange reps is maybe the best compromise between rep ranges designed to build strength (between, say, 3 and 5) and rep ranges designed to build endurance (anything above 12 or so). However, to maximize results, you should work your muscles in all 3 rep ranges.
Muscle fibers are "typed" according to their oxidative capacities and how fast they fatigue. Historically, fast-twitch fibers (the ones best suited for growth) are worked by a combination of lower-rep, lower set routines. Fine. Except that muscles are also made up of slow-twitch fibers. You can't very well ignore them if you want to maximize gains.
Therefore, you should juggle low-rep training (from 4 to 6 reps), intermediate-rep training (8-10), and high-rep training (12-15, or even 15-18) to make the best progress.
The II-B or Not II-B Principle
We just got done talking about fiber types. Well, true muscle physiology types (the kind that wear lab coats with the sleeves torn off) refer to these fibers using cute little alphanumeric terms, like II-A or II-B. These numbers refer to their oxidative capacity. Now, type II-B fibers are generally known as fast-twitch fibers and are the ones called on to do very heavy lifting. When you experience strength failure, much of it's due to the fact that these type II-B fibers have petered out?they just don't have the endurance of the other muscle fibers. They're like the fat truck driver who lives down the street; huge SOB, real strong, but can't run more than 10 feet without kissing the pavement.
After these fibers are fatigued, it's hard to engage them fully in subsequent exercises. However, the other fibers, the type II-A guys, will still be fresh, and they're best stimulated with reps of between ten and twelve.
The point here is that you should do your heavy weight, low-rep movements first in the workout. Then, after those fibers are baked, go on to your higher-rep movements.
The Rest Principle
Somewhere along the way, taking short breaks between sets got confused as "intensity". If, after all, you're breathing heavy like a high school kid at a Tracy Lord film festival, you must be working intensely, right? Wrong, Viagra breath. In weight lifting, intensity refers to how close the weight you're using is to your one-rep maximum. If I lift 200 pounds ten times, regardless of how much I huff and puff, I'm not engaging in a high-intensity set. If, however, I push 300 pounds up only 3 times, my intensity level is very high.
With that in mind, let me say that people tend to rush between heavy sets in order to maintain a high heart rate. Heart rate has nothing to do with your goal here. If you want aerobic capacity, run 10-miles a day and turn into one of those pairs of lungs with some sinew attached that you see whipping along the parkway every morning wearing T-shirts that say something like, "Greater Orlando 225K Grapefruit Extravaganza Race".
The more intense the set, the more rest is needed between sets to allow for neural recuperation. If you don't rest long enough between intense sets, it's a safe bet that your lactate levels will still be high and that they'll interfere with your performance on the next set.
Typically, if you're working heavy, you should rest between two and three minutes in-between sets. On less intense sets, you can rest anywhere from 45 seconds to 90 seconds.
The Time-Under-Tension Principle
Muscle growing isn't just about reps and rest periods. It all comes down to something called "time under tension". In some circles, time-under-tension refers to the amount of time you spend tailgating that Ford Pinto that's doing about 45 in the fast lane. It also refers to the time your muscles are actually working and weight, sets, and reps all play a part in the equation. For instance, if you do a set of 10 reps, but you pistoned them up and down like the pelvic thrusts of one of those horny baboons in a National Geographic special, your total time under tension was about two seconds. Muscle is not going to grow when your time under tension is inordinately low (see the next principle for more info on "time under tension").
Typically, and depending largely on your muscle fiber ratio (some people have more fast-twitch fibers than slow or vice versa), your time under tension should be anywhere from 30 seconds to about 70. Any more or any less is counterproductive over the long run. (Determining your exact muscle fiber make-up is probably a little more complicated than we want to get into here in this article).
As you progress from one set to another and you tire, you have one of two choices: reduce the weight, or reduce the number of reps. Given that choice, you should always reduce the weight and keep the rep range the same or roughly the same. In other words, if you just did 8 reps at 200, you'll need to reduce the weight about 4 or 5% on the next set in order to do 8 reps again.
The Change the Beat Around Principle
In the previous principle, we talked about time under tension and we mentioned the wisdom of keeping the duration of a set somewhere in the 30 to 70 second range. How do you do that without doing 30 to 70 reps? The answer is something called tempo. For instance, if I'm doing sets of dumbbell bench presses for sets of 4 to 6 reps, my time under tension is going to be something like 15 seconds if I do them at "normal" speed. However, if I slow them down, particularly on the eccentric, or lowering part of the movement, I'll increase time under tension.
Whenever you look at a Poliquin workout sheet, you'll see numbers that look like 302, or 501, or something similar. They do not refer to different styles of Levi's jeans. Instead, they refer to tempo, and the first number indicates how many seconds you should take to perform the eccentric portion of that particular lift. For instance, a "5" means you should take a count of five to lower the weight. The next number refers to the pause taken between the eccentric and the concentric portion of the movement, while the last number refers to how long it should take you to raise the weight.
Okay, so what this means is that if you're working in a 4-6 rep range, you have to adjust the tempo in order for that set's time under tension to reach at least 30 seconds. Along the same lines, if you're working in the 8-10 rep range, the tempo should be a little quicker so that you won't exceed the 30 to 70 second time-under-tension frame.
The Yin and Yang Principle
Muscle builders always talk about the endocrine system; the muscular system; or even the cardiovascular system. But, they hardly ever talk about the neurological system and that's a big mistake. Consequently, neural recuperation is ignored.
Ever wonder why 99 out of a 100 trainees do multiple sets of a particular exercise in succession? For instance, they'll do one set of bench press, followed by another set of bench press, followed by another set of bench press. In between, they'll pretend to pull a loose thread on their toe-jammy socks while sneaking a peak at Ms. Hooters while she's doing dumbbell flyes. This supposedly allows the athlete to recuperate in-between sets.
Well, amazingly, research has shown that you'll achieve better recuperation by performing a set for an antagonistic body part in-between sets. For instance, if you do a set of dumbbell bench presses, do a set for your lats in-between and then go back to your next set of dumbbell bench presses. You'll experience less of a drop in strength in between sets. No one is sure why, but you can bet it has to do with the neurological system.
Some of you who are new to Charles' workouts may have noticed that he often labels his exercises as "A1" and "A2" or "B1" and "B2". This refers to the order of exercises. "A1" is usually the first exercise for a particular set for a particular body part, while "A2" refers to the second exercise and that exercise is almost always for a dissimilar body part. After completing A2, the trainee rests for the predetermined amount of time and then goes back to his second set of A1.
Other examples include doing a set of barbell curls, followed by a set of triceps extensions; or a set of squats followed by a set of leg curls.
There are plenty of other Poliquin Principles, but my feeble brain can only digest so much. It's like buying panties for my wife out one of those big Victoria's Secrets clearance bins: they all look so nice, but I can only fit so many in my wheel barrow.
Anyhow, these are the ones that I use to formulate my workout programs. Next week, I'll show you how I use them to constantly formulate new, incredibly effective workouts without rupturing too many brain cells.
Part II
In Part I of this article, I carefully picked out seven of Charles Poliquin's principles and tried to make them a little easier to understand. Of course, as I mentioned, picking out only seven was a little like trying to pick my top seven favorite Hanson songs?okay, bad analogy. Trying to pick seven was like trying to choose which seven of my family or friends would get to go into the shelter with me when one of those Hollywood-movie asteroids blows up my town. Should I pick my dear, dear, grandmother, or that girl walking by who I've never met but who has a perfectly glorious rack? Anyhow, I made my choices based partly on cold logic and partly on emotion, picking some that worked particularly well for me or that suited my personality.
Hopefully, I made some of them easier to understand, especially if you're new to Charles Poliquin's ideas. Regardless of how well I explained them, though, they're essentially worthless unless they can be incorporated into a workable routine.
In the beginning, I practically had to book some time on a Craig Supercomputer to help me figure out a Poliquin workout for myself. I mean, geez, with all the other things I had to factor in like speed of contraction and muscle fiber types, etc., etc., I was lucky if I didn't get confused and mistakenly devise an elaborate tap-dance routine: De Camptown Ladies sing this song, oh da-doo-da-dey?.
Anyhow, I eventually got pretty good at it, but I found that I'm a little too goal-oriented and compulsive and I found that a completely pre-planned workout was causing me too much anxiety. I looked at the whole thing as a checklist and I couldn't relax and enjoy myself until I had methodically gone through the whole thing. It felt too much?like work.
So, I adapted. I devised a system using the Poliquin principles listed above and made a workout that had some structure, but was variable enough to suit my personality.
First, I arranged a seemingly logical split:
Day 1: Chest and Back
Day 2: Biceps and Triceps
Day 3: Off
Day 4: Quads, hams, calves
Day 5: Off*
*I don't work shoulders directly?I know that sounds nuts, but I think that anyone who habitually works chest and back is already getting plenty of shoulder work. My aim is to keep my shoulders healthy so that when I'm eighty, I can still throw lumps of stale bread at the pigeons that congregate around my park bench.
As I mentioned, I don't do well with set-in-stone structure. I need a little leeway to do what I want to do occasionally, or to have another choice or two in case the machine or weight I want is being used by some yutz who's telling his entire life story to his personal trainer in-between sets.
Therefore, I combine structure and spontaneity. Before I go into the gym, I've mapped out the first exercise (using the appropriate Poliquin Principles) for each body part I'm going to work that day and only the first exercise. As an example, the "written-down" portion of my chest and back workout will look like this:
A1) Incline Barbell Bench Press Weight Used Sets(4) Reps(4-6) Tempo(402) Rest(120secs)
1)
2)
3)
4)
A2) Wide-Grip Chin-Ups Weight Used** Sets(4) Reps(4-6) Tempo(402) Rest(120secs)
1)
2)
3)
4)
**With chins, I'd strap some additional weight onto my waist.
Again, these are the only two exercises that are set in stone for this particular workout. More on that later, but let's take a look at the parts of this exercise prescription and see which principles they employ:
The exercises themselves: Note the "A1" and "A2" designation? For you Poliquin neophytes, that simply means I'll do one set of the A1 exercise (the incline presses), rest two minutes, and then go on to the A2 exercise (the chins). I'll rest for another two minutes and then go on to the second set of the A2 exercise. This incorporates the "Yin and Yang" principle explained in Part I of this article which, in a nutshell, says that you experience better recuperation when you do another set for the antagonistic body part in-between sets. So, you might consider pairing chest and back; biceps and triceps; and quads and hams.
Reps: Sets of relatively low reps target the type IIB muscle fibers, and these are the fibers that have the least endurance. Therefore, I do these low-rep sets early in the workout while these particular muscle fiber types are still fresh (the "IIB or not IIB" principle).
Tempo: Note the 402 tempo indicated in my example workout. This tells me that I should take 4 seconds to lower the weight, no pause, followed by a 2-second concentric or lifting phase. By doing these slow, controlled reps, I'll ensure that my time under tension will be close to 30 seconds, which again suits these muscle fibers best (the "time under tension" principle, and the "change the beat around" principle).
Rest: Again, different muscle fiber types respond better to different rest periods, and type IIB fibers?which are being targeted here in my first group of exercises?respond better to longer rest periods. It may be difficult for traditional muscle builders to wait this long between sets, but it's the absolute correct thing to do if you're after additional strength and size.
Now, I'll record my weights and reps achieved for this workout, and I'll continue to do so for the next five workouts. Remember the "Borg Principle," the one that says your body becomes "hard-wired" to a particular routine? Well, it's true, and you really shouldn't do the same exercise or group of exercises more than 6 times in a row. After that sixth workout, I'll pick two new movements for chest and back. For instance, my "A1" movement might even be dips, doing 4 sets of one rep each, with a tempo of 15015 (that's right, 15 seconds on the way up and 15 seconds on the way down). Likewise, my "A2" movement might be close-grip chins for a 15015 tempo.
You're probably wondering why I record these first two exercises and no others. Well, as mentioned, the completely structured, completely-planned-beforehand workout doesn't work with me, mentally. I find myself thinking about the next set while I'm still doing the current one. But, by keeping careful records of the first movement for each body part, I can determine if my workouts continue to be effective. For instance, if I fail to either increase the weight or the reps on each subsequent workout, I know I'm not hitting it hard enough on the subsequent movements.
You, however, may prefer a lot of structure. If that's the case, simply write out your entire program beforehand using Chuck's principles. Just make sure you change your program after every 6th workout or so (that's every 6 workouts for that particular body part or parts).
Let me reiterate that the above exercise combo isn't my entire chest and back workout. Hardly. But after this, I free-wheel it, doing a combination of exercises that employ the Poliquin Principles but change constantly from workout to workout. This keeps me amazingly fresh (mentally) and allows me to keep making far more progress than I might have had I stuck to a completely pre-determined workout.
For instance, after I've done these first two low-rep exercises, I'll want to do some mid-range rep training (approximately 8-10). Consequently, I'll often do two exercises that:
A) Work the muscle slightly differently, i.e., flat-bench dumbbell presses instead of incline barbell presses, and bent-over rows instead of chin-ups.
B) Incorporate a slightly faster tempo. Since I'm doing 8 to 10 reps, I don't want to do incredibly slow reps because that will bring my total time-under-tension beyond the 30-70 second range I've established for myself. Consequently, my tempo will probably be about 202 or somewhere in that range.
C) Require less rest. Since, by doing higher reps, I'm working the fiber types that have greater recuperative abilities, I'll rest only about 60 seconds in-between sets.
Okay, so we've done a few sets in the low-rep range and the middle-rep range. That means that a good portion of your total number of muscle fibers have been recruited and put to work. That leaves your slow-twitch fibers. They've barely broken a sweat and they're laughing at all the low-endurance fibers that are gasping, wheezing, and massaging their bruised sarcomeres. Time to put these high-resistance fibers to work with some high-range rep training.
I've got several options here for doing high-rep sets, but generally, I'll throw out the Yin and Yang principle when I do them. In other words, I'll do the same exercise for three consecutive sets without bouncing back and forth between two exercises for two antagonistic muscle groups. Sure, the Yin and Yang principle is designed to allow for greater recuperation of a muscle groups, but given that you're doing work specifically for muscle fiber types that have great endurance, we can temporarily ignore the Yin and Yang principle during high-rep sets.
For instance, I might do three sets of dumbbell flyes for 12 to 15 (or even 15 to 18) reps each, with only 45 to 60 seconds of rest in-between sets. Then, after I've completed all three sets of flyes, I might do three sets of one-arm dumbbell rows, again doing 12-15 reps (per arm) and taking only 45-60 seconds of rest in-between sets.
There are other options, too. I might, on occasion, do three sets of vertical bench presses (machine), doing a 6,6,6, rep-scheme where I do 6 reps to failure, wait 10 seconds, reduce the weight, do 6 more reps, wait ten seconds again, and reduce the weight and do a final 6 reps. After resting for 45 seconds to 60 seconds, I'd do the next set. In this just-mentioned scenario, I'm using heavier weights than I might for a straight-out set of 15-18, but I'm still fatiguing the high-threshold slow-twitch muscle fibers.
Obviously, there are as many exercise possibilities as there are walrus bones in the dumpster of an Eskimo diner, but the key is, at least for me, to employ as many of the Poliquin principles as I can in each workout. Rules, of course, are occasionally meant to be broken, and I don't always hold fast to every principle 100% of the time. The key to being successful in this and any endeavor is to be creative. Experiment, but keep the basics in mind. Deciding to use hedge clippers to remove an ingrown toenail certainly falls under the category of creative, but it just isn't going to work that well, is it?
