In working out and trying to lose weight, one of the main ways to monitor your progress is by keeping track of the calories you burn. A very common calorie-burning exercise is the sit-up, also called the crunch. Depending on one's weight, an individual can burn between 400 and 800 calories per hour doing fast, vigorous sit-ups. Calculating the amount of calories burnt per hour doing sit-ups is quick and easy.

Instructions

  1. 1

    Determine the number of sit-ups you can perform in 1 minute. Follow the pace of your normal workout.

  2. 2

    Calculate the number of calories you burn per minute performing sit-ups. As a baseline, a 100-pound individual burns 6 calories per minute doing sit-ups. For every 4.54 Kilogram more you weigh, add 1 calorie per minute. For example, a 110-pound individual burns 7 calories per minute, a 120-pound individual burns 8 calories per minute, and so on.

  3. 3

    Divide the number of calories you burn per minute of sit-ups by the number of sit-ups you can perform in 1 minute. This is the number of calories you burn per sit-up. For example, here is the calculation for a 120-pound individual: 8 calories per minute / 30 sit-ups per minute = 0.27 calories per sit-up.
