The Claim
Increasing weekly resistance training volume is associated with greater muscle hypertrophy and strength gains, but the relationship exhibits diminishing returns, with strength gains demonstrating more pronounced diminishing returns than hypertrophy.
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.
More weekly resistance training leads to larger muscles and stronger muscles, but the benefits increase more slowly at higher volumes, and the strength gains slow down faster than muscle growth.
See the scientific wording
Increasing weekly resistance training volume is associated with greater muscle hypertrophy and strength gains, but the relationship follows a pattern of diminishing returns, with strength gains showing more pronounced diminishing returns than hypertrophy.
When you lift weights, your muscles make more protein to grow bigger, but after a certain point, they can't make any more protein no matter how much you train. Meanwhile, your nervous system gets better at using the muscles you have, but it hits a limit faster than muscle growth does, so strength stops increasing as quickly.
What the research says
1 studyDoing more weight training sets each week makes your muscles bigger and stronger, but after a while, extra sets give you less and less benefit—especially for getting stronger, not just bigger.
