Harvard Research Reveals 90 Minutes of Weekly Weightlifting Reduces US Mortality Risk by 19%

A pivotal study from Harvard University, which monitored 147,000 adults over three decades, concludes that engaging in 90 to 119 minutes of strength training weekly can lead to a 19% decrease in deaths from cardiovascular diseases, a 13% reduction in overall mortality, and a 27% drop in fatalities from neurological disorders. This research, published in the British Journal of Sports Medicine in June 2026, stands as the most extensive long-term examination of the relationship between resistance training and mortality to date. These findings hold particular significance for the United States, where heart disease persists as the primary cause of death and fewer than 25% of adults follow recommended strength-training protocols. Researchers indicate that the current exercise recommendations may significantly underestimate the potential of strength training as a means to extend life for American adults.
