You may have decided to lose weight.
Exercise burns lots of calories.
And not only do you vaporize that donut, bagel, or bag of chips as you work out, exercise elevates your metabolism, so you continue to use calories at an increased rate for several hours after you've showered and propped up your feet. Or you may not be worried about your weight, but you may want to find out how many calories you're burning in order to modify your food intake accordingly. To meet your weight control goals, it's helpful to know exactly how many calories your workout consumed. Just plug in your weight, activity, and your average pace for the distance. The calculator will tell you how many calories you burned during each hour of exercise.
