A groundbreaking new study has revealed that just one hour a week of simple, consistent weight training—split into two half-hour sessions—can significantly boost muscle strength and mass, challenging long-held beliefs about the time commitment necessary for effective resistance exercise. The findings, published in April 2025 in the journal Medicine & Science in Sports & Exercise, are likely to inspire busy Thais who cite lack of time as a barrier to exercise, as well as public health advocates eager to promote more accessible approaches to fitness (Washington Post).

A recent study shows that just one hour of weight training weekly, split into two 30-minute sessions, can substantially increase muscle strength and size. The findings, published in Medicine & Science in Sports & Exercise in April 2025, suggest a time-efficient approach that could appeal to busy Thai adults seeking healthier lifestyles. The results are echoed by health experts aiming to make resistance training more accessible in Thailand.

The research involved 42 healthy adults aged 18 to 40 with prior resistance training experience. Over eight weeks, participants followed a minimalist program of two supervised 30-minute sessions per week. Each session included nine full-body exercises targeting both upper and lower body muscles. After eight weeks, most participants showed measurable gains in muscle mass, strength, and power, regardless of whether they pushed to total fatigue or finished with some energy left.
