The Claim
Rest intervals of 1 minute versus 3 minutes during leg press training at 80% one-repetition maximum produce no significant difference in strength gains, as measured by 1RM increases of 26–31% after 10 weeks of training in young, untrained 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.
In young, untrained adults performing leg press exercises at 80% of their maximum strength for 10 weeks, rest periods of 1 minute and 3 minutes between sets result in the same increase in strength, with both groups gaining 26–31% in one-repetition maximum.
See the scientific wording
Rest intervals of 1 minute versus 3 minutes do not significantly affect strength gains in young, untrained adults performing leg press at 80% one-repetition maximum, as both conditions produced 26–31% increases in 1RM after 10 weeks of training.
When lifting heavy weights repeatedly with enough total work, the muscles and nerves adapt together: the nerves learn to fire more strongly and more often, and the muscle fibers get thicker, both of which make the person stronger — regardless of how long they rest between sets.
What the research says
1 studyWhether you rest for 1 minute or 3 minutes between heavy leg lifts, you still get about the same strength gains after 10 weeks — the study proved it.
