90 Minutes of Strength Training Per Week Is the Sweet Spot, Science Says
You've probably heard you need to train more. More sessions, more volume, more time. A new meta-analysis published in June 2026 offers a different answer — and a much more specific one.
The optimal range of strength training to reduce mortality risk sits between 90 and 119 minutes per week. Not more, not less.
The exact numbers
Within the 90 to 119 weekly minutes of resistance training window, researchers measured:
- 13% lower all-cause mortality risk
- 19% lower cardiovascular disease risk
- 27% lower neurological mortality risk
These reductions are statistically robust — and they're achieved with a training dose that most people will find genuinely accessible. 90 to 119 minutes spread across a week works out to 13 to 17 minutes per day.
Why this range, and not more?
Previous research already showed strength training is beneficial. What this study adds is the idea of an optimal dose. Beyond the identified range, benefits don't keep growing proportionally — they plateau, sometimes declining slightly.
That's not a reason to stop if you train more. It's mainly a counter-argument for people who think they're not doing enough. 90 to 119 minutes per week is a health dose — not a competitive athlete program.
What this means for structuring your week
In practice, that range maps to two sessions of 45 to 60 minutes per week. That lines up perfectly with the new ACSM guidelines, which recommend working all major muscle groups twice per week.
For someone just starting: three 30-minute sessions puts you in range. For someone training consistently for years: nothing changes, except the certainty that the benefits are stacking up.
Add cardio on top: the effects stack
Nothing in this study says you have to choose between strength training and cardio. The two work through different mechanisms. Combined, their effects on longevity add up. Strength training preserves muscle mass, bone density, and metabolic function. Cardio supports cardiovascular and respiratory health — and research shows it predicts lifespan more powerfully than most biomarkers.
So the question isn't strength vs cardio. It's: are you doing enough of both?
The number to remember
13 minutes per day. That's the lower bound of the optimal range. Less than one TV episode. More than most people currently do. If there's one thing to add this week, it's this: 13 minutes of strength training per day is enough to produce a measurable long-term health impact.
