The Claim
In trained men undergoing high-load lower-body resistance training, performing sets to muscle failure versus stopping 1–2 repetitions short of failure leads to equivalent improvements in leg press and leg extension 1-repetition maximum strength, with gains ranging from 22% to 34% over 10 weeks, indicating that reaching complete muscular failure is not necessary for maximal strength development when training close to failure.
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.
If you're a guy who lifts weights and gets close to failure—like stopping just 1 or 2 reps short—you'll get just as strong as if you pushed yourself to the absolute max. Over 10 weeks, both ways boost leg strength by 20–35%.
See the scientific wording
In trained men performing high-load lower-body resistance training, training to muscle failure and stopping 1–2 repetitions short of failure result in equivalent improvements in leg press and leg extension strength, with 1-RM increases of 22–34% over 10 weeks, demonstrating that reaching complete failure is not required for maximal strength gains when training close to failure.
When lifting heavy weights close to failure, the muscles get tired enough to activate all available motor units, and the muscle fibers reorganize to pack in more contractile units, making the muscle stronger without needing to push to complete exhaustion.
What the research says
1 studyIn guys who lift weights, pushing to absolute failure and stopping just 1–2 reps short led to almost exactly the same strength gains in leg exercises after 10 weeks. So you don’t need to go all the way to exhaustion to get maximally stronger.
