The Claim
Average power output during bench press declines significantly across four sets in both men and women under both one-minute and two-minute rest conditions, indicating that fatigue accumulates regardless of rest duration or sex.
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.
During four consecutive bench press sets, average power output decreases significantly in both men and women, whether they rest for one minute or two minutes between sets.

Average power output during bench press declines significantly across four sets in both men and women under both one-minute and two-minute rest conditions, indicating that fatigue accumulates regardless of rest duration or sex.
As muscles work repeatedly, they build up waste products like lactic acid and phosphate, which interfere with the muscle's ability to use calcium. Without enough calcium, the muscle fibers cannot contract strongly, so each rep gets weaker even if you rest briefly.
What the research says
1 studyBoth men and women got weaker with each bench press set, no matter if they rested for one or two minutes — meaning fatigue builds up no matter what. But women stayed stronger longer than men.
