Science fact-checking · Jul 19, 2026Women who lifted weights 80–120 minutes a week cut their risk of dying from any cause — peak benefit at 80 minutes. More than 150? No extra protection. Just 2 days a week of lifting could be the quietest longevity hack you’ve ignored. https://s.fitbodyscience.com/7kZKWd

The breakdown
Lifting weights for just 90 to 120 minutes a week might be the sweet spot for living longer — but more isn’t always better.
Other research found that women who lifted weights for about 80 to 120 minutes a week were less likely to die from any cause compared to those who didn’t lift at all, with the strongest benefit around 80 minutes. Doing more than 150 minutes didn’t offer extra protection and might have carried some risk, but the range mentioned in the post falls safely within the beneficial zone. This finding comes specifically from studies on women, so it’s not clear if the same pattern holds for everyone.
Bottom line
If you’re lifting weights, sticking to roughly an hour and a half a week seems like a smart move — but don’t feel like you need to go overboard.
ReliabilityThe evidence mostly supports this with some caveats
