2 short sessions work
A new study says just two brief strength-training sessions a week can maintain fitness, strength and balance — basic moves like squats and push-ups are enough. The research and reporting emphasize that short, consistent sessions beat sporadic long workouts for busy schedules ( ).
The findings were released as an American College of Sports Medicine Position Stand in Medicine & Science in Sports & Exercise on March 5, 2026 (Vol. 58, No. 4, doi:10.1249/MSS.0000000000003897). (ncbi.nlm.nih.gov) Authors conducted an overview of reviews that synthesized 137 systematic reviews encompassing more than 30,000 participants to update the ACSM guidance last revised in 2009. (ncbi.nlm.nih.gov) The analysis reported significant improvements versus no exercise across multiple outcomes including muscle strength, hypertrophy, power, endurance, contraction velocity, gait speed, balance and other physical-function measures. (ncbi.nlm.nih.gov) For increasing voluntary strength, the Position Stand identified heavier loads (≥80% of one‑rep max), performance through a full range of motion, and doing 2–3 sets early in sessions as beneficial training features. (ncbi.nlm.nih.gov) Muscle hypertrophy showed stronger responses with higher weekly volumes (≥10 sets per muscle group) and eccentric overload, while power gains were maximized with moderate loads (30–70% 1RM), lower-to-moderate volume and explosive/olympic-style movements. (ncbi.nlm.nih.gov) The review found several commonly touted variables—training to momentary fatigue, equipment type, exercise complexity, set structure, time under tension, blood-flow restriction and periodization—did not consistently change the primary training outcomes. (ncbi.nlm.nih.gov) ACSM concludes that adults should perform progressive resistance training with prescriptions tailored to specific goals and that this Position Stand is the College’s most comprehensive resistance‑training update in 17 years; supporting materials including an infographic and slide deck are available on the ACSM site.
