The recommended amount of physical activity for adults per week to maintain health is at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity exercise. This guideline helps reduce the risk of chronic diseases, improve mental health, and enhance overall well-being. Additionally, incorporating muscle-strengthening activities on two or more days per week is encouraged for optimal health benefits. Consistent physical activity supports cardiovascular fitness, aids weight management, and promotes healthy aging, making regular movement essential for maintaining physical health.
