The Apparent Confusion About Progressive Overload

Apparently, there is a growing disagreement online about progressive overload. Most of it comes from confusing cause and effect, while different people use the same term to mean slightly different things.

Brosef’s explanation from the bench next to you usually goes like this: you get stronger by continually adding more weight to the bar. Since strength and load rise together, it must be the added weight that produced the improvement.

This explanation makes intuitive sense and works reasonably well for beginners, who often improve fast enough to add weight almost every workout. However, it puts the plates before the muscle by mistaking the visible result of progress for the process that made it possible.

The process of building strength starts when you expose the body to a challenging training stimulus. In response, the body may improve neural coordination, become more efficient at the movement, and increase its ability to produce force. Once those adaptations occur, the same weight becomes easier relative to your new capacity. At that point, you can adjust the training demand by adding weight, reps, or changing another variable to keep the stimulus productive.

This creates a repeating cycle:

Training stimulus → Adaptation → Improved performance → Adjusted stimulus

Or, more simply:

You perform a set of five reps → You get stronger → That same set becomes easier → You add some weight to keep it challenging.

Increasing the load can help drive further adaptation, but the increase works best when supported by the capacity you have already developed. When someone forces more weight before their performance has improved, range of motion often shortens, technique breaks down, and control suffers. The number on the bar went up, but the ability being trained likely did not.

Another point of disagreement is how broadly progressive overload should be defined. Some people use it almost exclusively to mean adding weight. Others include more reps, better execution, increased range of motion, or more total work. These can all change the training demand, but they do not demonstrate the same kind of progress.

Adding a rep with the same load, range of motion, and technique provides clear evidence of improved performance. Adding another set increases total training volume, which may be useful for hypertrophy, but it represents a programming adjustment rather than direct evidence that performance on a given exercise has improved. Better execution or greater range of motion may also represent meaningful improvement, although changing the conditions of the movement makes comparison less direct.

Progression works best when it responds to meaningful improvements in capacity rather than forcing the numbers upward at all costs. You apply an appropriate stimulus, recover, monitor performance, and increase the demand when your performance supports the adjustment.

This brings us back to the original confusion between cause and effect. Because the weight on the bar usually increases as you become stronger, it's easy to assume that adding weight is what created the strength. The process works as a cycle: the existing training stimulus produces adaptation, that adaptation improves performance, and improved performance allows you to increase the demand. The heavier load then becomes part of the next stimulus and may contribute to further adaptation.

Progressive overload is therefore the ongoing adjustment of training demands as the body adapts. The controversy becomes much easier to understand once you recognize that progression can be both the result of the adaptation that came before it and part of the stimulus that produces what comes next.
