Physical exercise helps burn calories, turning the nutrients from the foods we eat in our daily diet into energy.
Not all physical activities, however, use the same amount of energy and not all bodies react the same way.
The U.S.D.A. provides a list of the average amount of calories that are burned from doing different exercises for different time periods. These figures are based on the averages for a man that weighs about 154 pounds. Keep in mind that people who weigh more will burn more calories and people who weigh less will burn less.
