Two groups trained with weights: one pushed until they couldn't do another rep, the other stopped 4–6 reps before failure. After 5 weeks, both got equally better at holding a weight without tiring.

After five weeks of strength training using either light or heavy effort levels, people show less stability in their muscle force during sustained, moderate-intensity contractions as they become fatigued, and the level of effort used during training does not affect this decline.
In adults who regularly lift weights, performing resistance exercises with either low or high effort close to failure for five weeks leads to about a 10% increase in maximum knee extension strength, and the level of effort does not affect the amount of strength gained.
When people train with light effort and low fatigue using 80% of their maximum strength, their nerve signals to muscles become more frequent, but this does not change how those muscles are activated when they are tired and working at only 30% of their maximum strength.
In adults who regularly lift weights, performing workouts close to failure or with some reserve in the last rep produces similar improvements in how long they can sustain effort, with no meaningful difference between the two approaches.
When performing sustained muscle contractions at 30% of maximum strength, both low and high repetition resistance training lead to similar increases in electrical signals from motor units as the muscle fatigues, suggesting that more powerful motor units are activated over time in both cases.
