I hate exercising. But I do love counting up the calories I burn when finally get off the couch.
Today, I shoveled for an hour and a half. When I finally came inside, I had to see the numbers. Each one of these websites gives a different number of calories burned.
Calories per hour
Webmd fitness calorie counter
Health Status calculator
Health Discovery calculator
Then get mean.
The mean is the average of the numbers. It is easy to calculate: add up all the numbers (the calories burned from each website), then divide by how many numbers there are (how many websites you used).
