Strength training: small dose, big gains
New syntheses show roughly 60 minutes of resistance work per week can cut all‑cause mortality by up to ~15%, so you don't need daily max‑effort sessions to get major health returns (menshealth.com) (runnersworld.com). For injury prevention, experts stress single‑leg movements for balance and flat, non‑compressible shoes under heavy lifts to reduce common mishaps (runnersworld.com) (toptenreviewed.com).
A 2022 systematic review in the American Journal of Preventive Medicine pooled 10 prospective studies and reported that any resistance training (vs none) was associated with a 15% lower all‑cause mortality risk (RR=0.85; 95% CI=0.77–0.93). (research.usq.edu.au) That same paper’s dose–response subanalysis (four cohorts) identified the steepest benefit at roughly 60 minutes per week (RR≈0.74, a maximal ~27% reduction) and noted that mortality reductions tapered off at higher weekly volumes. (research.usq.edu.au) A separate British Journal of Sports Medicine meta‑analysis of 16 cohort studies found 10–17% lower risk for all‑cause mortality and major non‑communicable diseases from muscle‑strengthening activity and described a J‑shaped dose‑response with the largest gains at about 30–60 minutes/week. (bjsm.bmj.com) Public‑health guidance frames that weekly signal into practice: WHO and the U.S. CDC recommend muscle‑strengthening that targets major muscle groups on at least two days per week, a pattern that aligns with splitting modest weekly resistance time into multiple short sessions. (who.int) Coaching outlets and runner‑focused sources single out unilateral moves for injury resilience, repeatedly naming Bulgarian split squats, step‑ups and slow single‑leg deadlifts as key drills to correct imbalances and train the body in the single‑leg loading pattern of running. (runnersworld.com) Fitness authorities and shoe guides recommend flat or weightlifting shoes with rigid, non‑compressible soles for heavy squats and deadlifts because a stiff sole improves force transfer and stability versus cushioned running shoes. (nasm.org) Systematic reviews of lifting injuries report that the spine, shoulder and knee are the most commonly affected sites in strength sports, while single‑leg strength work has been associated in cohort and coaching reports with lower rates of common running overuse problems such as patellofemoral pain and Achilles tendinopathy.
