How often should adults engage in muscle-strengthening activities?

Engaging in muscle-strengthening activities at least two days per week is supported by health guidelines recommended by organizations such as the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC). This frequency is suggested because it allows for adequate recovery time for the muscles while promoting muscle strengthening, endurance, and overall functional fitness.

Strength training helps to increase muscle mass, improve bone density, enhance metabolic rate, and can contribute to improved performance in daily activities. The two-day minimum ensures that individuals are consistently challenging their muscles, which is essential for maintaining strength and functional ability as one ages.

This frequency strikes a balance between efficacy and manageability, allowing individuals to incorporate strength training into their weekly routine without overtraining, which could lead to injuries or burnout. Thus, the recommendation to engage in such activities at least twice a week is crucial for optimal health benefits.
