If you do not have any medical restrictions, the Centers for Disease Control and Prevention recommends engaging in a minimum of 150 minutes of moderate intensity aerobic exercise, or 75 minutes of vigorous exercise, and at least two strength training sessions per week. Examples of moderate-intensity exercises include brisk walking, water aerobics, cycling on mostly level ground, and doubles tennis. Vigorous-intensity exercise examples include jogging or running, swimming laps, singles tennis, basketball, and cycling fast or on hills.
