Lifting weights for about one to two hours a week may support longer life, especially when combined with aerobic activity.<\/p>\n

A few sets with weights may seem like a small part of a weekly routine, but the effects may reach far beyond stronger arms or a more defined physique. Evidence is increasingly<\/a> pointing to strength training as a habit that may support a longer life, even for people who are not spending hours in the gym.<\/p>\n

The analysis used data from three major US studies<\/a> that followed nearly 150,000 nurses and other health professionals for as long as 30 years. Every few years, participants reported how much time they spent doing strength training and aerobic exercise, including walking, cycling, and swimming. Because almost 36,000 participants died during the study period, the data allowed the study authors to examine how muscle-building activity was linked with the risk of early death.<\/p>\n

Strength has a sweet spot<\/p>\n

They found a clear sweet spot. People who did around 90 to 120 minutes of strength training a week \u2013 or roughly an hour and a half to two hours \u2013 had about a 13% lower risk of dying from any cause than those who did none.<\/p>\n

The strongest associations appeared for two major causes of death<\/a>. Strength training was linked with a 19% lower risk of death from cardiovascular disease (which includes heart disease and stroke) and a 27% lower risk of death from neurological conditions, mostly dementia.<\/p>\n

Interestingly, more wasn\u2019t necessarily better. Beyond about two hours of weightlifting a week, risk didn\u2019t fall any further.<\/p>\n

The lowest risk of all was seen in people who paired strength training with regular aerobic exercise \u2013 measured across everyday activities such as walking, jogging, cycling and swimming. Doing at least the recommended amount of moderate aerobic activity (around 150 minutes a week) was on its own linked to between a 26% and 43% lower risk of death.<\/p>\n

But combining plenty of aerobic activity with one to two hours of strength training brought the risk down furthest of all \u2013 by around 45%. Aerobic exercise still did most of the heavy lifting, but the two clearly work best together, not as rivals.<\/p>\n

There was one exception to the pattern: for cancer deaths, only smaller amounts of strength training (under an hour a week) were linked to lower risk.<\/p>\n

Muscle and mortality<\/p>\n

So why would weightlifting help us live longer? The answer lies in muscle \u2013 and what muscle actually does, beyond simply helping us move around.<\/p>\n

Muscle, specifically the skeletal muscle we build through resistance training, is one of the body\u2019s most metabolically active tissues<\/a>. After a meal, it\u2019s where most of the sugar, or glucose, in our blood is sent. Insulin, the hormone released when we eat, signals muscle to absorb glucose from the bloodstream, and it mops up around 80% of it<\/a> \u2013 either burning it for energy or storing it as glycogen, a ready fuel reserve, rather than letting it circulate or be stored as fat.<\/p>\n

Keeping muscle strong and plentiful therefore helps the body manage blood sugar<\/a> and protects against type 2 diabetes<\/a>, itself a major driver of heart disease and early death<\/a>.<\/p>\n

Muscle is also an organ in its own right. When muscles contract, they release hormone-like messengers called myokines<\/a> into the bloodstream. These help to dampen the chronic, low-grade inflammation<\/a> that quietly underlies heart disease, diabetes, and many cancers.<\/p>\n

Myokines also allow muscle to communicate<\/a> with the liver, fat tissue, blood vessels, bone, and even the brain. They send out signals that influence how those organs burn fuel, control blood flow, and stay healthy. In effect, every time we use our muscles, they release a burst of chemical signals that benefit the rest of the body.<\/p>\n

Strength reflects whole-body health<\/p>\n

The heart and circulatory system benefit too. Over time, regular resistance training can help lower blood pressure and keep arteries flexible rather than stiff<\/a>, which protects against cardiovascular disease.<\/p>\n

Strength itself is also a remarkably good barometer of health. Grip strength \u2013 how hard you can squeeze with your hand \u2013 is widely used as an indicator of whole-body strength. In one large international study, grip strength predicted the risk of dying early even more accurately than blood pressure<\/a>. Stronger muscles also mean fewer falls and fractures<\/a>, more independence in later life and less frailty as we age \u2013 all of which shape how long, and how well, we live.<\/p>\n

The link between strength training and brain health is newer and less certain, but plausible. Resistance training appears to drive beneficial changes in the brain<\/a>. The same improvements in blood sugar and blood vessels that protect the heart are also tied to a lower risk of dementia<\/a>. That may help explain the 27% drop in deaths from neurological disease the study found.<\/p>\n

Modest routines may be enough<\/p>\n

It\u2019s worth being clear about what this study can and can\u2019t tell us. It was observational, so although it can show a strong link between strength training and a longer life, it can\u2019t prove that one directly causes the other.<\/p>\n

People who lift weights may be healthier in other ways, though the researchers adjusted for many such factors, including diet, smoking, and aerobic activity. Strength training was also self-reported, and the study couldn\u2019t capture how hard people trained.<\/p>\n

The encouraging message is that the amount linked to a longer life is genuinely achievable. You don\u2019t need a gym membership or a heavy barbell, either. Two short sessions a week where you work all the major muscle groups<\/a>, alongside some aerobic exercise each day, appears to be plenty when it comes to improving your overall health and longevity.<\/p>\n
