Cellular
Single-set resistance training performed to failure elicits greater hypertrophy gains compared to submaximal effort, although differences are modest.
Practitioners may consider incorporating training to failure for enhanced muscle growth.
StrongSupportsmedium confidence
Several measures of hypertrophy tended to favor FAIL, although absolute differences between conditions were generally modest.
Why this rating
Based on the randomized controlled trial design.
