How many situps do you have to do to burn 500 calories?

For a 160 pound person performing situps at a moderate rate, it will take a little less than 2 hours of continuous situps to burn 500 calories. It will take less time for people who weigh more and will take longer for those who weigh less.

Situps are not a great exercise for burning calories, but they can strengthen your abdominal muscles well. Compare it to running at 8 miles per minute, where the same 160 pound person can burn almost 500 calories in only 30 minutes.
