Muscle-strengthening exercise and all-cause mortality and longevity: a meta-analysis of prospective cohort studies
Momma H, et al.
High-confidence evidence from multiple solid studies
Summary
A meta-analysis integrating 16 prospective cohort studies evaluating the association between muscle-strengthening exercise habits and all-cause mortality and disease-specific death risks. 30–60 minutes of weekly muscle-strengthening exercise was found to significantly reduce all-cause mortality, cardiovascular death risk, and cancer death risk.
Key findings
- 1
30–60 min of weekly muscle-strengthening exercise reduces all-cause mortality by 10–20%
- 2
Cardiovascular death risk reduced by 17%, cancer death risk reduced by 12%
- 3
Combining with aerobic exercise provides an additional 10–20% reduction in death risk
- 4
Benefits plateau above 60 min/week with some evidence of potential reverse effects at very high volumes

Grip strength and all-cause mortality and cardiovascular disease risk: a large prospective cohort study
The Lancet, 2015
A large prospective cohort study (PURE study) following 142,861 participants across 17 countries. Grip strength was strongly inversely associated with all-cause mortality and cardiovascular mortality risk. Each 5 kg decrease in grip strength was associated with 16% higher all-cause mortality and 17% higher cardiovascular death risk, suggesting grip strength may be a superior cardiovascular risk marker than blood pressure.
Effects of resistance training on bone mineral density: a meta-analysis
British Journal of Sports Medicine, 2015
A pooled analysis of RCTs examining the effects of resistance training on bone mineral density (BMD) at the spine, hip, and femoral neck. Significant BMD increases were found at all sites, with particularly large effects in postmenopausal women.
Resistance training and mental health outcomes including depression and anxiety: a meta-analysis
JAMA Psychiatry, 2018
A meta-analysis evaluating the effects of resistance training on depressive symptoms, anxiety, and general mental health. Analyzing 33 RCTs, resistance training was found to significantly reduce symptoms of depression and anxiety. Effect sizes were medium to large (d = 0.66), suggesting mental health benefits comparable to or exceeding aerobic exercise.
