Shorter, Harder Workouts May Be Enough — New Meta-Analysis Sparks Debate for Thai Gym-Goers and Public Health
A major new meta-analysis suggests you may not need hours in the gym to build noticeable strength: doing just two truly challenging “direct” sets in a session — and roughly four to six sets per muscle group per week — can drive strength gains, while muscle size increases tend to plateau at about 11 “fractional” sets per session. The finding, published as a SportRxiv preprint and summarised by university press offices and health outlets, reframes how trainers think about time-efficient strength work and has clear implications for busy Thai adults, workplace wellness programmes and national physical-activity campaigns. (The study is currently a preprint and still awaiting full peer review, so experts urge cautious application while more research is completed.) (SportRxiv preprint PDF)
