According to the Centers for Disease Control and Prevention (CDC), adults should get at least 150 minutes of moderate-intensity activity or 75 minutes of vigorous-intensity activity—or a combination of the two—each week. Examples of physical activity include walking, running, swimming, and cycling. The CDC also recommends that two days a week, you work to strengthen your muscles. Whether that involves using bodyweight exercises, dumbbells, gym equipment, or resistance bands, these activities should work all the major muscle groups of your body—legs, hips, back, chest, abdomen, shoulders, and arms. What’s more, these muscle-strengthening activities should be done in addition to your physical activity.
