Effects of resistance training performed to repetition failure or non-failure on muscular strength and hypertrophy: A systematic review and meta-analysis

Methodology

Meta-analysis

Population

Multiple studies; trained and untrained adults

Intervention

RT to volitional failure vs RT not to failure (stopping with repetitions in reserve)

Findings

Training to failure does not produce superior strength or hypertrophy outcomes compared to non-failure training when volume is equated. Some evidence suggests always training to failure may be detrimental for strength — proximity to failure matters more than complete failure itself.

Outcome measures

Muscular strength, muscle hypertrophy

Limitations

Limited number of studies directly comparing failure vs non-failure with equated volume; heterogeneity in failure definitions.
