Proximity to failure and its impact on hypertrophy and strength

Training closer to failure on a per-set basis can benefit hypertrophy, while there is no significant relationship between proximity to failure and strength. For hypertrophy, training closer to failure leads to greater increases in muscle size. However, for strength, proximity to failure does not seem to drive strength adaptations. The paper emphasizes that training closer to failure can be beneficial for hypertrophy but not necessarily for strength, with load and other factors playing a more significant role in strength gains.
