TL;DR
A large-scale study indicates that consistent weight training for 90 minutes to two hours weekly can lower the risk of premature death by up to 13%. Combining strength and aerobic exercises yields even greater benefits. The findings suggest strength training is a vital component of healthy aging.
New research confirms that engaging in 90 minutes to two hours of weight training per week can lower the risk of premature death by up to 13%, highlighting the importance of strength-based exercise for long-term health.
The study analyzed data from three long-term studies involving 147,374 men and women over a 30-year period. Participants who regularly performed weight training within the specified timeframe showed a 13% reduction in all-cause mortality risk. The risk of death from cardiovascular disease decreased by 19%, and from neurological diseases like dementia, the reduction was 27%. The research also found that individuals combining high levels of aerobic and strength training experienced up to a 58% decrease in early death risk.
Experts note that doing more than two hours of strength training weekly did not significantly increase benefits, suggesting a threshold for optimal gains. The findings support the idea that resistance training can help prevent or delay health issues associated with aging, such as heart disease, stroke, and neurological decline.
Why It Matters

It offers evidence that weight training can contribute to longer, healthier lives and may reduce pressure on healthcare systems by preventing chronic diseases. For individuals, it highlights a practical way to improve health outcomes through manageable exercise routines.

Background
While the benefits of aerobic exercise like running, cycling, and swimming are well established, the role of resistance or weight training in reducing mortality risk has been less clear. Previous studies suggested health benefits but lacked definitive links to longevity. This new research consolidates evidence over three decades, emphasizing strength training’s role in healthy aging.
“Strength-based physical activity is a powerful tool, particularly in support of healthy ageing – helping prevent or delay poor health, keeping us mobile and independent.”

What Remains Unclear
It is still unclear whether there is an upper limit to the benefits of strength training beyond two hours per week, as the study found no additional gains with more than that. The long-term effects of different types of resistance exercises and how they interact with other lifestyle factors also remain under investigation.
