how many days are you supposed to exercise a week
Weekly Cardio Minimum. The Centers for Disease Control and Prevention recommend that all adults engage in at least 2 1/2 hours of moderate aerobic activity per week. If you do intense cardio, you can get away with half that time. You may spread your exercise over as many days of the week as you like, as long as each session lasts at least 10 minutes. In addition, the CDC recommends that all adults engage in some physical activity for 30 minutes a day, at least five days a week.
