The Claim
In resistance-trained individuals, single-set resistance training performed to muscular failure does not result in greater improvements in muscular strength or local muscular endurance compared to single-set resistance training performed with two repetitions in reserve over an 8-week training period.
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 already used to lifting weights, going all the way to failure on each set doesn't give you better strength or endurance gains than stopping two reps short — at least over 8 weeks.
See the scientific wording
Single-set resistance training performed to failure does not produce greater increases in muscular strength or local muscular endurance compared to training with two repetitions in reserve in resistance-trained individuals over an 8-week period.
When lifting weights to failure or stopping two reps before failure, the body recruits the same number of muscle fibers and activates the same nerve signals to the muscles. After a certain point, pushing harder does not add more muscle activation or growth because the nervous system already fully engages the muscle fibers needed for that workload.
What the research says
1 studyIf you're already experienced with weightlifting, doing one set of exercises until you can't do another rep doesn't make you stronger or give you better endurance than stopping two reps before failure—over eight weeks, both ways work just as well.
