The Claim
In previously untrained young women, 10 weeks of resistance training at 70% of one-repetition maximum results in similar increases in maximal strength (26–29%) and muscular endurance whether sets are performed to muscular failure or stopped short of 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.
In young women new to weight training, 10 weeks of lifting at 70% of their maximum strength leads to the same gains in strength and endurance whether they push to muscle failure or stop before failure.
See the scientific wording
In previously untrained young women, 10 weeks of resistance training using 70% of one-repetition maximum (1RM) produces similar increases in maximal strength (26–29%) and muscular endurance regardless of whether sets are performed to muscular failure or stopped short of failure, indicating that training to failure does not enhance these outcomes.
When lifting a moderate weight, the body recruits all the muscle fibers it needs to complete the set, whether the person stops early or pushes until exhaustion. Once enough fibers are activated to move the weight, adding more effort doesn't recruit more fibers or make them stronger.
What the research says
1 studyFor young women just starting weight training, lifting until exhaustion doesn’t make them stronger or more enduring than stopping a few reps early—as long as they do about the same total number of reps. The study found no extra benefit from pushing to failure.
