Beyond about two hours of weightlifting a week, risk didn&#8217;t fall any further.<\/p>\n<p>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. <\/p>\n<p>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<p>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%.

The answer lies in muscle \u2013 and what muscle actually does, beyond simply helping us move around.<\/p>\n<p>Muscle, specifically the skeletal muscle we build through resistance training, is one of the body&#8217;s most <a href=\"https:\/\/doi.org\/10.1093\/ajcn\/84.3.475\" rel=\"nofollow noopener\" target=\"_blank\">metabolically active tissues<\/a>. After a meal, it&#8217;s where most of the sugar, or glucose, in our blood is sent. <\/p>\n<p>Insulin, the hormone released when we eat, signals muscle to absorb glucose from the bloodstream, and it <a href=\"https:\/\/doi.org\/10.2337\/dc09-S302\" rel=\"nofollow noopener\" target=\"_blank\">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<p>Keeping muscle strong and plentiful therefore helps the body <a href=\"https:\/\/doi.org\/10.2337\/dc23-0800\" rel=\"nofollow noopener\" target=\"_blank\">manage blood sugar<\/a> and protects against <a href=\"https:\/\/doi.org\/10.1001\/archinternmed.2012.3138\" rel=\"nofollow noopener\" target=\"_blank\">type 2 diabetes<\/a>, itself a <a href=\"https:\/\/doi.org\/10.1056\/NEJMoa1008862\" rel=\"nofollow noopener\" target=\"_blank\">major driver of heart disease and early death<\/a>.<\/p>\n<p>Muscle is also an organ in its own right. <\/p>\n<p>When muscles contract, they release hormone-like messengers called <a href=\"https:\/\/www.nature.com\/articles\/nrendo.2012.49\" rel=\"nofollow noopener\" target=\"_blank\">myokines<\/a> into the bloodstream.

Over time, regular resistance training can help lower blood pressure and <a href=\"https:\/\/doi.org\/10.3390\/jcm10163492\" rel=\"nofollow noopener\" target=\"_blank\">keep arteries flexible rather than stiff<\/a>, which protects against cardiovascular disease.<\/p>\n<p>Strength itself is also a remarkably good barometer of health. <\/p>\n<p><img decoding=\"async\" width=\"1200\" height=\"675\" src=\"https:\/\/www.newsbeep.com\/ca\/wp-content\/uploads\/2026\/06\/weightlifting-woman-tattoos.jpg\" alt=\"A young women lifting weights, to illustrate that strength training is good for longevity \" class=\"wp-image-177566\"   loading=\"lazy\"\/>Why would weightlifting help us live longer?

Resistance training appears to <a href=\"https:\/\/doi.org\/10.1016\/j.arr.2024.102356\" rel=\"nofollow noopener\" target=\"_blank\">drive beneficial changes in the brain<\/a>. <\/p>\n<p>The same improvements in blood sugar and blood vessels that protect the heart are also tied to a <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/39096926\/\" rel=\"nofollow noopener\" target=\"_blank\">lower risk of dementia<\/a>. <\/p>\n<p>That may help explain the 27% drop in deaths from neurological disease the study found.<\/p>\n<p>It&#8217;s worth being clear about what this study can and can&#8217;t tell us.
