Harvard Study Finds 90-120 Minutes of Weekly Strength Training Cuts Death Risk 13%

Summary
Nearly 150,000 adults tracked over 30 years saw the biggest longevity gains at 90-120 minutes of weekly strength training, with benefits flattening after about two hours.
That range was linked to a 13% lower risk of death from any cause, a 19% lower risk of cardiovascular death, and a 27% lower risk of death from neurological disease versus no lifting.
Researchers said the target is a benchmark rather than a strict prescription because the data did not capture training type, intensity, or set volume in detail.
The strongest result came from combining resistance work with aerobic exercise: people doing both had a 45% lower mortality risk than those doing neither.
The study, published in the British Journal of Sports Medicine, reinforces a practical message that consistent, functional strength work matters more for healthy aging than simply doing more volume.
Why do the life-extending benefits of strength training seemingly vanish after just two hours a week?
Does lifting weights make you live longer, or do healthier, wealthier people just happen to lift?
If muscle is a key longevity organ, what is the exact 'prescription' for preventing diseases like dementia?
Optimal Strength Training Duration: 90–120 Minutes Weekly Lowers Mortality by Up to 45%
Overview
A major study published in June 2026 in the British Journal of Sports Medicine has advanced our understanding of how strength training can help people live longer, healthier lives. By analyzing data from over 147,000 participants collected across three decades and multiple large health studies, researchers found clear evidence that resistance exercise significantly reduces the risk of death. The study not only showed a strong link between strength training and lower mortality but also provided specific guidelines for how much exercise is optimal. This research highlights the importance of regular strength training as a key part of a healthy lifestyle.
