Strength Training Now Ranks Equal to Cardio for Longevity and Health

For many years, health advice focused on aerobic exercise for heart health and a long life. Now, new research shows that strength training is just as vital, especially from middle age onwards. Major health bodies are updating their recommendations to reflect this shift. The World Health Organization now stresses the need for regular muscle-strengthening sessions. The American College of Sports Medicine goes further, advising adults to do moderate- to high-intensity strength training at least two to three times a week.

Skeletal muscle does more than help movement. It acts like an endocrine organ, releasing myokines that control inflammation and improve insulin sensitivity. This helps lower the risk of chronic diseases like type 2 diabetes and metabolic syndrome.

Aging brings sarcopenia, the loss of muscle tissue, which weakens mobility and metabolic function. Strength training counters this by building muscle and improving mitochondrial function. These changes slow biological aging and reduce the risk of falls and fractures in older adults. Relying only on cardio is no longer seen as enough to prevent age-related decline. Resistance and strength training are now key to maintaining muscle mass, bone health, and overall well-being. Experts agree these exercises play a crucial role in healthy aging.
