How often should adults engage in physical activity for optimal musculoskeletal health?

For optimal musculoskeletal health, adults should engage in physical activity at least two days a week at moderate intensity. This recommendation is grounded in the understanding that regular physical activity helps maintain and improve muscle strength, flexibility, and bone density, which are essential components of musculoskeletal health. Engaging in moderate-intensity activities promotes better functionality, reduces the risk of injuries, and helps manage weight—factors that collectively contribute to overall musculoskeletal well-being.

This approach allows for variability in exercise routines, incorporating different forms of strength training as well as aerobic activities, further enhancing the benefits. A robust regimen that includes targeted strength exercises and flexibility training at least twice a week is effective for promoting lifelong health and preventing conditions like osteoporosis and sarcopenia.
