Strength training: simpler wins
New coverage of ACSM guidance argues simple, moderate strength routines produce real benefits — you don’t need complex programs to build strength — and Brock University research finds supervised weight training is safe for kids. (runnersworld.com), (stcatharinesstandard.ca) Also, GLP‑1 weight‑loss drugs are quietly reshaping gym culture and who shows up to lift. (self.com)
ACSM published a new Position Stand on resistance training on March 17, 2026 after reviewing 137 systematic reviews covering more than 30,000 participants. (acsm.org) The statement explicitly shifts emphasis to consistency over complicated programming and lists concrete targets: training all major muscle groups at least twice weekly, ~80% 1‑RM for 2–3 sets to prioritize strength, and roughly ~10 weekly sets per muscle group for hypertrophy. (acsm.org) The ACSM authors also note nontraditional modes—elastic bands, bodyweight and home‑based routines—produce meaningful gains, and that training to momentary failure or elaborate periodization is not required for most healthy adults. (acsm.org) Brock University launched a 12‑week study recruiting children aged 8–11 to examine how supervised resistance sessions (two sessions per week) affect muscle and cardiovascular systems, with participants visiting the lab seven times during the protocol. (brocku.ca) The Brock team led by Andrew McKiel and James Maynard is using newer, non‑invasive EMG signal‑processing techniques instead of needle EMG to track neuromuscular activation and better understand whether and how children’s muscles hypertrophy. (brocku.ca) Industry and analysts link the GLP‑1 medication boom to rising interest in resistance training: a KFF‑based estimate reported roughly one in eight U.S. adults had used these meds by mid‑2024, and industry data show 2024–25 increases in free‑weight use (dumbbell use up 6.7% year‑over‑year and +28% since 2021). (axios.com) Gym operators and professional bodies are adapting—some chains are piloting GLP‑1‑friendly programming or partnerships, and surveys of trainers show roles shifting toward medical‑adjacent support and muscle‑preservation coaching as clients combine drugs with exercise.
