High-repetition training is not systematically the most effective method for improving muscular endurance (the ability to maintain force over time).

Greg Nuckols points out that the relationship between the number of repetitions and muscular endurance is more complex than it appears. He relies on a meta-analysis by Hackett et al. (2018) published in the 'Journal of Science and Medicine in Sport'. This meta-analysis, which constitutes a high level of evidence, shows that while high-repetition training does indeed promote endurance, low-repetition training (heavier loads) can also induce significant gains in this area. The common misconception that one must exclusively perform high repetitions to progress in endurance is therefore nuanced by these results. The analysis is solid because it challenges a common fitness simplification through a rigorous reading of the scientific literature. There is no exaggeration here, but rather an invitation to diversify training methods to optimize performance.
