Strength training: just two sessions
New guidance says consistency beats complexity — just two weekly resistance sessions totaling 30–60 minutes can deliver major health and injury-prevention benefits (sciencedaily.com) (healthline.com). Experts are also flagging simple targeted moves, like cable internal shoulder rotations, to protect joints while you lift and run (motra.com).
The American College of Sports Medicine released a Position Stand titled “Resistance Training Prescription for Muscle Function, Hypertrophy, and Physical Performance in Healthy Adults,” published in Medicine & Science in Sports & Exercise in 2026 and listing Brad S. Currier and colleagues among the authors. (read.qxmd.com) The guidance is an “overview of reviews” that synthesized 137 systematic reviews and evidence from more than 30,000 adult participants using databases current to October 2024. (r2.magickimg.com) For specific prescription details, the Position Stand cites strength protocols using heavier loads (around 80% of one‑rep max) for 2–3 sets per exercise, hypertrophy goals targeting roughly 10 sets per muscle group per week, and power work using moderate loads (about 30–70% 1RM) with an emphasis on fast concentric intent. (acsm.org) The authors report that nontraditional formats—elastic bands, bodyweight training and home‑based programs—produce meaningful improvements, while factors like training to failure, machine versus free‑weight choice, and complex periodization did not consistently change outcomes for the average healthy adult. (acsm.org) This Position Stand is the first major ACSM update on resistance training since 2009, a 17‑year interval that the society and affiliated researchers note reflects a substantial expansion in the evidence base. (acsm.org) Exercise guides and rehab resources describe the cable internal shoulder rotation as an isolation movement that primarily targets the subscapularis and is regularly used in prehab and rehab protocols to improve shoulder stability.
