The Claim
Muscle hypertrophy occurs similarly across a range of resistance training proximity-to-failure levels, from low velocity loss (<20%) to momentary failure, suggesting a non-linear relationship where moderate proximity-to-failure (20–40%) may be sufficient for optimal growth without requiring maximal fatigue.
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.
You don’t need to push your muscles to absolute exhaustion to grow them—working them pretty hard (but not all the way to failure) might give you just as much muscle growth as going all out.

What the research says
1 studyThe study found that lifting weights until you’re totally exhausted doesn’t make your muscles grow more than stopping a bit earlier — so you don’t need to push to absolute failure to get strong and big.
