The Claim
Muscle hypertrophy in trained male athletes increases with moderate resistance training volumes (32–41 sets/week) and plateaus at volumes exceeding 60 sets/week.
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.
In trained male athletes, muscle growth increases with moderate weekly resistance training volumes of 32 to 41 sets but stops increasing when training exceeds 60 sets per week.
See the scientific wording
Muscle hypertrophy in trained male athletes occurs robustly at moderate resistance training volumes (32–41 sets/week) but plateaus beyond 60 sets/week, suggesting an upper limit for volume-induced growth in this population.
When muscles are worked hard, they sense the stress and turn on a growth signal called mTORC1. This signal tells the muscle to build more protein and get bigger. But after a certain amount of work, the muscle stops responding to this signal as strongly, so even if you keep training more, it doesn't grow any further.
What the research says
1 studyIn trained athletes, lifting weights 40 times a week builds muscle just as well as lifting 60 times — doing more doesn’t help. The study found no extra muscle growth from the higher volume.
