The Claim
There is insufficient evidence to determine whether very high per-session resistance training volumes (>20 sets) attenuate muscular or strength adaptations or continue to provide benefit, and therefore the point at which no further outcome superiority is detectable should be interpreted with caution.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
We don’t know yet if doing more than 20 sets of weight training in one session helps you get stronger or if it’s just too much and stops helping—so don’t assume there’s a clear cutoff point where more sets stop being useful.
See the scientific wording
There is insufficient evidence to determine whether very high per-session resistance training volumes (>20 sets) attenuate adaptations or continue to provide benefit, so the point of undetectable outcome superiority should be interpreted cautiously.
What the research says
1 studyStudy: Is There Too Much of a Good Thing?
The study found that doing more sets per workout helps build muscle and strength — but only up to a point, after which extra sets don’t help much. It also says we don’t have enough data yet to know if doing way more than 20 sets is helpful or harmful, so we should be careful about assuming it’s always good.
