Does anyone know how many calories are burned doing ab crunches? It's listed under strength train, but I assume they burn calories too. Thanks!!

I tried to look it up for you...i'll attach a couple of things that I found:

To compare how different exercises burn calories, based on a person who weighs 150 lbs., walking briskly burns about five calories per minute. Doing vigorous crunches burns about seven calories per minute, which is about the same as doing aerobic exercise. Most people, however, can walk briskly or do aerobics a lot longer than they can do abdominal crunches, so finding an activity that you can do for 30 minutes is more beneficial when it comes to burning calories than exercises that you can do for only brief periods of time.


Crunching is a very intensive exercise, but only a small amount of muscle is active. They will use up between about 300 and 800 Calories an hour, or about 5-12 Calories per minute.

If you can keep them up for an hour, that's fantastic, because you must be using a lot of abdominal muscles to help with the work. Most crunches only work the Rectus Abdominis, which is the surface layer at the front of your belly. Even the twisty ones, which claim to involve Obliques (the deeper muscles at the sides), CANNOT activate these properly, because of the lying position in which they are performed.

Normally, crunches can't be used to burn a significant amount of energy, because they concentrate the effort on a small amount of muscle tissue, and wear it out very quickly.

Large muscles, such as the glutes (buttock) and vasti (thigh, often WRONGLY called 'quads') are usually activated if a large number of calories need to be used in a short time.



I also found that it DOES depend on your height and weight...so most of these are prob wrong...I'd say the best answer would be to get one of those things that measures how many calories you burn in the day...I want to get one but I don't know where you buy them

Log crunches as Calisthenics under cardio and it will give you the calories burned based on your current weight.

Do you understand what calesthenics are? I would imagine that would greatly overestimate the burn.
