Gaining muscle strength and increasing muscle mass may not require grueling workouts or extreme physical exertion, according to new research from Australia.
Scientists at Edith Cowan University found that meaningful improvements in muscle growth, strength, and physical performance can be achieved without pushing the body to exhaustion or experiencing severe post-workout fatigue.
Professor Ken Nosaka, Director of Exercise and Sports Science at the university, argues that the widespread belief that effective exercise must be painful or exhausting often discourages people from maintaining an active lifestyle.
The study highlights the benefits of eccentric exercise, a type of movement that focuses on the phase in which muscles lengthen while remaining under tension. Everyday examples include walking downstairs, slowly lowering oneself into a chair, or controlling the downward movement of a weight.
Published in the Journal of Sport and Health Science, the research found that muscles are capable of generating greater force during these lengthening actions while requiring less energy than other forms of muscle contraction. As a result, individuals may achieve significant training benefits without excessive fatigue.
Researchers also emphasize that muscle soreness should not be viewed as a necessary sign of progress. Instead, consistent participation in eccentric exercises can enhance strength and fitness without placing undue stress on the body.
Another key advantage is accessibility. Movements such as slow chair squats, controlled calf raises, and wall push-ups can be performed at home without specialized equipment. According to the researchers, even a few minutes of these exercises each day may contribute to noticeable improvements in strength and overall health.
The approach may be particularly beneficial for beginners, older adults, and individuals living with certain chronic health conditions, as it places less demand on the cardiovascular and respiratory systems than more strenuous forms of exercise.
“These movements closely resemble activities people already perform in everyday life, making them practical and easier to sustain over time,” Professor Nosaka said, adding that long-term consistency is often more important than training intensity alone.
