Runners need about 30 to 120 minutes of strength training each week on 2 or more days for longevity. Strength training means muscle-strengthening activity that works all major muscle groups at moderate or greater effort. That range covers both the baseline for adults and the doses linked to lower death risk in large studies. More lifting past about two hours per week did not add further benefit.

What the large studies found
In 147,374 health professionals followed up to 30 years, 90-119 minutes per week of strength training was tied to 13% lower all-cause mortality than none, according to Harvard T.H. Chan School of Public Health in the Harvard longevity report.
The benefit flattened at 120 or more minutes per week, with no further reduction. The same 90-119 minute group also had 19% lower cardiovascular death and 27% lower neurological-disease death, including Alzheimer's and Parkinson's, as reported by ScienceAlert covering the Harvard study. The lowest risk came from combining strength work plus aerobic exercise such as running.
Why 30 minutes can still count
A pooled analysis of 16 cohort studies linked muscle-strengthening activity to 10-17% lower all-cause, cardiovascular, cancer and diabetes mortality, according to the British Journal of Sports Medicine via the pooled mortality analysis. Benefit peaked at 30-60 minutes per week in a J-shaped curve.
For time-pressed runners, that matters. One or two focused 20-30 minute sessions can reach the range where risk was lowest in that analysis. The World Health Organization advises adults to do muscle-strengthening activities involving all major muscle groups on 2 or more days per week for added health benefits, noted in the World Health Organization fact sheet.
What type helps runners most
In trained runners, strength training improves running economy by about 2-8% and time-trial and sprint performance without reducing VO2max or increasing body weight, according to a Type A Training evidence review in the runner strength review. Running economy means less oxygen used at the same pace.
Most positive runner trials used 2-3 sessions per week for 6-14 or more weeks, progressing to heavy loads plus plyometrics. Light high-rep circuits had the weakest evidence. Heavy means challenging leg work such as squats, deadlifts, lunges, and calf raises, plus jumps and short hops for power.
How to fit it around running
Place two full-body sessions on easy-run or rest days. Keep runs easy before lifting, and keep at least one harder run apart from leg day. Progress load slowly and stop sets before form breaks.
These longevity findings are observational and largely self-reported among mostly U.S. health professionals, so they show links rather than proof. Treat strength as a complement to running, sleep, and medical care, and check with a clinician after injury, heart disease, or long layoff.
- Pick 4-6 moves: squat, hinge, lunge, calf raise, row, and press
- Do 2-4 sets of 3-8 hard reps for legs, plus 20-40 total jumps
- Rest 2-3 minutes between heavy sets
- Add one upper-body and core move for balance
