The amount of calories you burn will depend on how long you exercise and the intensity of the activity. Choosing a higher intensity activity will burn more calories than a lower intensity activity. Lower intensity activities require more time to burn the same amount of calories. Adding faster intervals into an activity session also increases your calorie use.
Your weight is another factor when it comes to burning calories. A heavier person actually burns more calories than someone who is lighter when they exercise for the same amount of time.
