For most people, MayoClinic.com recommends a minimum of 150 minutes of moderate exercise, such as jogging, each week for basic physical fitness. Workouts should be spaced out during the week. For example, you might jog 30 minutes a day five days a week.

If you jog five days a week, your workouts need to average 60 minutes each to reach this goal.
