Harvard study finds 90‑120 minutes of weekly strength training cuts mortality risk

Researchers at Harvard School of Public Health identified that performing 90 to 119 minutes of resistance training each week lowers the risk of death from any cause by 13% over a 30‑year span. The study also reported reductions of 19% for cardiovascular deaths and 27% for neuro‑degenerative diseases when such strength training is combined with regular aerobic activity.

A complementary piece from Brazil explains the concept of power training, emphasizing how fast, controlled movements complement traditional strength work to improve daily functional abilities, prevent falls, and preserve autonomy as people age. Both articles highlight the health benefits of incorporating speed and resistance exercises into regular fitness routines.

The research, published in the British Journal of Sports Medicine, underscores that moderate weekly volumes—roughly 1½ to 2 hours—are sufficient for longevity gains, and that adding aerobic exercise (600‑880 minutes per week) further amplifies the protective effect.
