1.5–2 Hours of Strength Training per Week May Boost Longevity

A 30-year study of 147,374 participants found that 90–120 minutes of weekly strength training is linked to about 13% lower all-cause mortality, with a 19% lower risk of cardiovascular death and a 27% lower risk of death from neurological disease; benefits do not increase beyond 120 minutes per week, suggesting 1.5–2 hours weekly as a practical longevity target. The findings are observational and based on self-reported activity, so causation cannot be established.
