The Claim
Increasing resistance training volume from 40 to 60 sets per week does not result in additional muscle hypertrophy in trained male athletes who are non-responders to lower-volume training.
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.
For trained male athletes who do not gain muscle from lower-volume resistance training, increasing the number of sets per week from 40 to 60 does not lead to further muscle growth.
See the scientific wording
Increasing resistance training volume from 40 to 60 sets per week does not overcome non-responsiveness to muscle hypertrophy in trained male athletes, as non-responders to initial training showed no additional muscle growth despite higher volume.
When muscles are trained, they reach a point where their ability to build new muscle protein stops increasing, no matter how much more they are worked. This limit happens because the signals that tell muscles to grow become fully turned on and cannot get any stronger, so extra workouts don't make more muscle.
What the research says
1 studyEven when athletes who didn’t grow muscles from regular training did way more lifting, they still didn’t grow more muscles. More sets didn’t fix the problem.
