Does two hours of strength training a week reduce the risk of early death?
A study of more than 147,000 adults links 90 minutes to two hours of weekly weight training with lower risks of early death, heart disease, and dementia.

BBC Persian says a review of three long-running studies found regular weight training is tied to a lower risk of premature death, with the clearest benefits at about 90 minutes to two hours a week. More than two hours did not appear to add extra benefit.
It is like tightening the bolts on a bike a little each week: a small amount of strength work can help the body stay sturdy. This study suggests about two hours a week may help people live longer and stay healthier.
Analysis
What the study found
Researchers reviewed data from three studies involving 147,374 men and women over 30. The analysis, published in the British Journal of Sports Medicine, found that people who regularly did about 90 minutes to two hours of weight training a week had a 13% lower risk of dying from any cause.
The article says the associations were stronger for some specific causes of death. Cardiovascular deaths, including heart attacks and strokes, were down by 19%, while deaths from neurological diseases such as dementia or cognitive decline were lower by as much as 27%.
How it fits with other exercise
The piece contrasts this with the clearer public understanding of aerobic exercise such as running, cycling, and swimming, which the NHS already links to lower risks of heart disease, stroke, type 2 diabetes, and stress. The new analysis suggests resistance training also plays an important role.
The article also says the largest drop in early-death risk was seen among people who combined strength work with high levels of aerobic activity. In that group, the risk of dying early from any cause was reported to fall by as much as 58%.
What experts say it may do
The BBC Persian report quotes trainers and health officials describing strength work as useful for ageing well, maintaining mobility, preserving independence, and reducing pressure on health systems. It also notes practical benefits people commonly report, including better energy, stronger bones, improved blood sugar control, less joint pain, and sharper focus.
The caveat is important: the findings show a link, not a proof that weight training alone caused the lower mortality. Still, the article presents the evidence as strong enough to suggest that a modest weekly dose of strength training can be a meaningful part of long-term health.
Key points
- A review of three studies covering 147,374 adults linked 90 minutes to two hours of weekly weight training with lower premature-death risk.
- The reported reductions were 13% for all-cause mortality, 19% for cardiovascular deaths, and up to 27% for neurological disease deaths.
- The article says extra strength-training time beyond about two hours did not appear to add more benefit.
- Experts quoted in the piece argue strength work can support ageing, mobility, bone strength, and independence.
If the pattern holds, a modest weekly dose of strength training could help lower deaths from heart disease, stroke, and some nerve diseases. It may also help people stay mobile and self-sufficient as they age.
The study is based on observed links, not a trial, so it cannot prove that weight training alone caused the lower risk. The report also suggests that doing more than two hours a week may not bring additional gains.
