Meta-Analysis
Pro
Grgic J et al. · 2022Sports MedicineMeta-analysis found a small but statistically significant benefit of training to failure for muscle hypertrophy compared to not training to failure. The effect was more pronounced in untrained individuals and when fewer sets were performed.

Santos WDN et al. · 2022Frontiers in PhysiologySystematic review found that training to failure may provide a small hypertrophy advantage when training volume is equated, but the practical significance is questionable. Training close to failure (1-3 reps in reserve) appears sufficient for most trainees.

Carroll KM et al. · 2019Journal of Strength and Conditioning ResearchRCT in trained lifters found that training to failure did not produce superior hypertrophy compared to submaximal training when volume was matched. Training to failure also resulted in greater fatigue accumulation, potentially limiting total training volume over time.
