ACSM flips strength advice
The American College of Sports Medicine's new guidance says any resistance training — even simple bodyweight moves — delivers real muscle and health benefits, with consistency prioritized over perfection. Experts behind the update stress sustainability and long-term engagement as the main objective for strength gains and longevity ( ).
The guidance is published as an ACSM Position Stand titled “Resistance Training Prescription for Muscle Function, Hypertrophy, and Physical Performance in Healthy Adults: An Overview of Reviews,” appearing in Medicine & Science in Sports & Exercise (April 1, 2026 issue) and listing Stuart M. Phillips and Brad S. Currier among the lead authors. (read.qxmd.com ) Authors synthesized an umbrella review of 137 systematic reviews covering more than 30,000 participants, with the literature search window reported as current to October 2024. (read.qxmd.com ) The Position Stand lists a general-health prescription of training all major muscle groups at least two days per week using moderate-to-heavy loads as a baseline recommendation for adults. (acsm.org ) The review identifies specific dose-response effects: voluntary strength was most consistently improved by heavier loads (≥80% one-repetition maximum), performed for roughly 2–3 sets, early in a workout, and at least twice weekly. (read.qxmd.com ) Muscle hypertrophy emerged as volume-sensitive, with greater gains tied to higher weekly set volumes (roughly ≥10 sets per muscle group) and benefits from eccentric overload, while power adaptations were favored by moderate loads (≈30–70% 1RM), lower-to-moderate volume, and power-specific methods such as Olympic-style lifts. (read.qxmd.com ) The authors also report several commonly promoted variables—training to momentary failure, exercise complexity, set structure, time under tension, blood-flow restriction, and periodization—did not show consistent effects across the reviewed trials. (read.qxmd.com ) ACSM released a news package and supporting materials alongside the paper on March 17–18, 2026, including a slide deck and infographic summarizing the Position Stand and the organization’s announcement that this is the first major update to resistance-training guidance since 2009.
