There is an optimal dose of resistance training for longevity, with a maximal protective effect occurring at around 90 to 120 minutes per week.

The advice is based on recent observational evidence (notably a large prospective study published in the British Journal of Sports Medicine in 2026). These data show a robust association between this weekly duration and a reduction in the risk of all-cause, cardiovascular, and neurological mortality. It is important to note that these results are observational: they suggest a correlation but do not prove a direct cause-and-effect relationship. The idea of a "plateau" or a lack of additional benefit beyond 120 minutes is commonly observed in these cohorts, but does not mean that excessive training is deleterious. Research also underscores that benefits are maximized when muscle strengthening is combined with regular aerobic activity. Finally, previous meta-analyses, such as that by Momma et al. (2022), confirm the non-linear nature of this relationship, often described as a J- or U-shaped curve depending on the statistical models used.
