Strength training linked to longer life and reduced dementia risk
A long-term observational study of about 150,000 US health professionals found that doing roughly 90–120 minutes of strength training per week is associated with about a 13% lower risk of death, with stronger effects for cardiovascular disease (19%) and neurological disease (27%). Benefits peak around two hours weekly, and combining strength work with regular aerobic activity yields the largest reduction in mortality (about 45%). The study cannot prove causation and relies on self-reported exercise, but it suggests that two short weekly strength sessions plus daily aerobic activity can meaningfully support longevity.
