The Minimum Effective Dose of Strength Training
The minimum effective dose of strength training for longevity is about 2 sessions a week, roughly 30 to 60 minutes total. Any resistance training is linked to about 15% lower all-cause mortality, peaking around 60 minutes weekly. This is the longevity-minimum dose, not the muscle-building dose, which needs more volume and progressive load. What changes after 40: higher training volume adds more lean mass in women 45 and older, and protein's muscle benefit plateaus around 1.6 g/kg/day, but works less well with age.
Understand the mortality link A meta-analysis of 10 cohort studies found any resistance training linked to about 15% lower all-cause mortality (19% lower cardiovascular mortality, 14% lower cancer mortality) compared with none
This is the best current summary of resistance training and death risk across multiple long-term cohort studies.
See the dose response Within that same meta-analysis, the mortality benefit peaked around 60 minutes of resistance training per week (up to about 27% lower risk), then flattened with more volume; this specific finding came from just 4 of the 10 studies, so treat it as suggestive
More is not always better for the longevity signal specifically, though this dose-response finding rests on fewer studies than the headline 15% number.
Cross-check against another meta-analysis A separate meta-analysis of 16 studies found the lowest mortality risk at about 30 to 60 minutes of muscle-strengthening activity per week, a J-shaped curve
An independent meta-analysis landing on a similar weekly range strengthens confidence in the roughly 30 to 60 minute target.
Add aerobic activity too Combining strength training with aerobic activity is linked to about 40% lower all-cause mortality, a bigger reduction than either alone
Strength and aerobic training appear to add complementary benefit rather than substitute for one another.
Train twice a week, full body 2 sessions per week, about 20 to 30 minutes each: 3 sets of a squat (or leg press) and 3 sets of a push-up (or bench press), taken close to a hard effort
This hits the roughly 30 to 60 minute weekly range linked to the lowest mortality risk in both meta-analyses, using two of the most trainable, well-studied movement patterns.
Consider more volume, if you have the time Across 14 randomized trials in women 45 and older, a higher training volume added about 1.3 kg of lean mass versus about 0.9 kg on a lower dose; both beat doing nothing (effect size 0.52 vs 0.34). Evidence quality is graded LOW
This is suggestive, not settled: it comes from fewer, smaller trials than the mortality data above, and it is specific to women past midlife, not a general over-40 rule.
Favor heavier load with multiple sets, if optimizing strength Across 178 studies (n=5,097), every combination of load, sets and frequency beat doing nothing. For strength specifically, higher load with multiple sets ranked top; for muscle size, doing multiple sets mattered more than the load used
This is the largest head-to-head comparison of training variables in the literature, and it confirms that the floor above works: something beats nothing at every dose tested.
Aim for around 1.6 g/kg/day of protein, spread across meals The muscle-building benefit of extra protein plateaus around 1.6 g/kg/day of bodyweight (confidence interval roughly 1.0 to 2.2 g/kg/day, wide). The same review found protein supplementation worked less well with age, not better
This caps how much extra protein is worth chasing, and the age finding is a reason to prioritize the training dose above rather than assume supplements alone close the gap.
This is the best current summary of resistance training and death risk across multiple long-term cohort studies.

Is this for you
- Anyone who thinks they don't have time to strength train
- People wanting the minimum effective dose, not a bodybuilding program
- Beginners looking for a simple, evidence-based starting point
- Anyone who already does cardio and wants to add strength training for a bigger mortality benefit
Cautions
- This is the minimum dose linked to lower mortality risk in observational cohort studies; it is a longevity-minimum, not a muscle-building minimum. Building visible size or strength requires more weekly volume and progressive overload over time
- All the mortality figures here are 'linked to' associations from cohort studies, not randomized proof that lifting weights itself causes a longer life, though the pattern repeats across independent meta-analyses
- The specific dose-response curve (benefit peaking near 60 min/week) comes from a smaller subset of studies (4 in Shailendra's analysis) than the headline association; treat the exact number as a reasonable target, not a precise threshold
- The best dose-response data on lifting comes from trainees averaging about 25 years old. The over-40 evidence is thinner: mostly women, low certainty, and short. Nobody has run the big volume trial in this age group yet
- New to resistance training, pregnant, or managing a heart, joint, or other medical condition: check with a doctor before starting, and learn basic form before adding load
