You Need

Every person needs to get a certain level of physical activity just to stay in good physical shape. Each week, you should be engaging in AT LEAST150 minutes of sensible aerobic exercise or 75 minutes of energetic aerobic exercise, plus a minimum of two strength-training sessions. And if you want to lose weight, you may need to work out even more. Stretching is compulsory too, during your warm-up and cool-down — and possibly as a separate practice if you want the additional mind-body benefits of yoga or tai chi, for instance.

These workout goals can be fairly intimidating if you’re new to an exercise program and are unsure of how to fit them into a full and hectic schedule.
