Building muscle: your program may not need more complexity

A new position stand, not 30,000 new volunteers

The 2026 American College of Sports Medicine position stand synthesized 137 systematic reviews covering more than 30,000 participants. It examined resistance training in healthy adults. This is an overview of existing research, not a single new trial; its search was current to October 2024.

What mattered—and what was less consistent

The synthesis found that resistance training improved muscle size and strength compared with no training. Higher weekly volume, including categories of at least ten sets per week, favored hypertrophy. Heavier loads favored maximal strength. Those are different outcomes, and a strength-specific finding should not automatically become a muscle-growth rule.

Training to momentary muscle fatigue, equipment type and periodization did not consistently change outcomes across the included evidence. That does not prove every option is identical or that effort is irrelevant. It means the review did not establish a consistent advantage for making those features compulsory.

Try a program audit before a program overhaul

Here is an editorial audit, not a workout prescription. Pick one exercise you already perform and inspect your last few records. Can you tell which variation you used, what range of motion you intended, how many repetitions you completed and what load you moved? If not, a new exercise list may add uncertainty rather than insight.

Consider an invented example: “bench press, 70 kg, 8 reps” becomes “bench press, 72.5 kg, 8 reps.” That is a clear change in recorded performance only if the exercise conditions are comparable. A shorter range of motion or a different machine changes the comparison.

Now ask what you actually want to improve. A single-rep strength estimate and a muscle-size measurement answer different questions. Treating one as perfect proof of the other makes it harder to judge a program fairly.

Ten sets is not a universal passcode

A category used in a research synthesis is not a personal threshold at which growth suddenly starts. It does not mean nine sets never work, or that adding sets indefinitely is beneficial. A useful program decision still needs to account for what you can perform, repeat and recover from.

As a bookkeeping exercise, list where each muscle is trained during your week. Keep direct work and work from compound exercises identifiable rather than casually counting every set as the same stimulus. The point is to see the program clearly before changing it.

Choose a change you can evaluate

Write down what you are changing and which observation would make you keep it. That could be more repeatable sessions, a clearer progression record or better tolerance of the existing plan. This is a way to make a decision auditable, not a claim that one metric proves muscle gain.

Our one-rep-max and RPE tools can make load assumptions visible. They do not measure hypertrophy, verify technique or tell you to attempt the calculated maximum. A simpler program with interpretable records can be easier to evaluate than a sophisticated one whose moving parts keep changing.
