Calories Burned Calculator
Energy use during exercise is usually estimated from METs, where one MET is roughly what the body burns sitting still. Pick an activity, enter your weight and how many minutes you spent, and the tool returns the calories burned along with the rate per minute and per hour. You can also type in a MET value of your own when the activity you want is not on the list. These are population averages, so fitness, terrain and technique will move your own figure either way.
