Strength training goes mainstream
‘Strengthmaxxing’ is the hottest fitness trend this spring — experts stress consistent resistance work and correct form over viral fads, positioning strength as preventive 'aging insurance.' Coverage points to rising public interest and practical tips for adults to prioritize protein, resistance work, and longer‑term consistency ( ).
The American College of Sports Medicine published its first major resistance‑training position stand in 17 years, synthesizing 137 systematic reviews spanning more than 30,000 participants to update evidence on muscle function, hypertrophy and performance. (acsm.org) The new ACSM guidance gives concrete prescriptions — training all major muscle groups at least twice weekly, lifting heavier loads (around 80% of one‑rep max) for strength, and targeting roughly 10 weekly sets per muscle group for hypertrophy. (acsm.org) Les Mills’ 2026 Global Fitness Report surveyed more than 10,000 fitness consumers and identifies “strength and wellness” as the twin drivers of member growth, noting motivation for mental wellbeing rose 29% since 2021. (lesmills.com) A large Danish randomized trial of 451 retirement‑age adults found one year of supervised heavy resistance training preserved leg extensor strength at a four‑year follow‑up (mean age 71; 61% women). (bmjopensem.bmj.com) Muscle‑tissue research reviewed in Mayo Clinic coverage (n=197) concluded resistance training can slow or reverse age‑related muscle‑fiber changes and that people who start after age 70 can still build muscle into their 80s. (mcpress.mayoclinic.org) Nutrition guidance for older adults is shifting upward: U.S. resources recommend about 1–1.2 g protein/kg/day for older adults, while academic sources suggest 1.2–1.6 g/kg/day for those 50+, which equals roughly 90–120 g/day for a 165‑lb person. (acl.gov) Market and media signals show the movement is social and commercial — TikTok’s 2026 trend work highlights health‑focused cultural shifts, Les Mills reports Gen Z is the main source of new gym joins, and industry data indicate about 78% of U.S. gyms offer personal training to support supervised strength instruction.
