Note: Figures are based on moderate (as opposed to vigorous)
activity. A heavier person burns more calories, so the same amount of physical activity
can actually burn the same number of calories but more quickly. But remember, exercising
harder and faster only increases the calories expended slightly. To burn more calories it
is better to exercise for a longer time.
Determining how many calories you burn is not an exact science. This number should only be
used as an estimate of calorie expenditure. Courtesy of the Calorie Control
