Exercise is essential for keeping your body strong, boosting your mood, and staying healthy as you age. Watch above as Dr. Chugh lays out the recommendations for adults 18 to 64: at least 150 minutes of moderate-to-vigorous activity a week—think jogging or cycling—two strength-training sessions targeting major muscle groups, several hours of light activity like walking or standing, and no more than eight hours of total sedentary time. By moving regularly, you’ll support your overall well-being.
