How often should I lift weights? Twice a week, and more is not better
How often should I lift weights: meta-analyses put the sweet spot at 30 to 60 minutes of resistance training a week. Past about 130 minutes the survival curve flattens and may reverse.

Key takeaways
- 30 to 60 minutes of resistance training a week tracked with roughly 10 to 20% lower all-cause mortality.
- The benefit plateaus and possibly reverses beyond about 130 to 140 minutes a week.
- Combining strength work with aerobic activity beats either alone.
Cardio has owned the longevity conversation for decades. The resistance training data has quietly caught up.
The dose-response curve
A 2022 meta-analysis in the British Journal of Sports Medicine pooled 16 prospective cohorts. Muscle-strengthening activity tracked with 10 to 17% lower risk of all-cause mortality, cardiovascular disease, cancer and diabetes. The curve was J-shaped: benefit rose fast to roughly 30 to 60 minutes a week, plateaued, then drifted back toward baseline past about 130 to 140 minutes.
Why the reversal is probably not what it looks like
Very high self-reported training volumes in observational data often flag other things, competitive athletes, people compensating for poor health, or simple recall error. The honest reading is that there is no evidence of extra survival benefit past an hour a week, not that lifting more actively harms you.
What that looks like in practice
| Session | Pattern | Example |
|---|---|---|
| Day 1 | Push + hinge | Push-ups, Romanian deadlifts |
| Day 2 | Pull + squat | Rows, goblet squats |
| Either day | Carry | Farmer's walk, loaded walk |
Two sessions of 25 to 30 minutes clears the studied dose.
The part that actually matters
Grip strength and leg power predict independence in later life better than most blood markers. The reason to lift at 45 is so you can still stand from a chair unaided at 85. Keep the upper body in it too: presses, rows and a few delt exercises protect the shoulders you will need for lifting and reaching later on.
Frequently asked
Is bodyweight training enough?
For general health, yes, push-ups, squats, rows and carries cover the major patterns. Progression matters more than the equipment.
Should older adults lift heavy?
Supervised progressive resistance training is well studied in adults over 65 and improves strength, bone density and fall risk. Start light, progress slowly.
