The Claim
Resistance training performed to momentary muscular failure does not produce greater muscle hypertrophy than resistance training performed before reaching momentary muscular failure, with a trivial effect size of 0.12 (95% CI −0.13 to 0.37), indicating that achieving complete muscular failure is not necessary for maximizing muscle growth in healthy adults.
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.
Lifting weights until you can't do another rep doesn't help you build more muscle than stopping before you hit total exhaustion—so you don't need to push yourself to the absolute limit to get the best results.

What the research says
1 studyThis study looked at whether lifting weights until you can't do another rep makes your muscles grow more than stopping before you're totally exhausted. It found no real difference — so you don’t need to push to absolute failure to build muscle.
