none - crunches burn a few calories but they also make belly look bigger - they do not burn fat
cardio is the only fat burning exercise and you can burn those calories running or jogging

There are so many different versions of crunches and undoubtedly it varies from person to person, so it's pretty hard to say how many crunches it would take to burn 150 calories. Doing cardio exercise allows for a more accurate prediction of calories burned. I'd say do about 30 min of cardio per day and check out a table of common exercises and weights to determine how many calories you're burning. Also, remember by doing the crunches you'll be gaining muscle which metabolizes more energy (calories) than does fat. Good luck!

You'll be doing crunches forever before you even come close to 150 calories. Try walking or running instead. or even biking. Just don't crunches won't help you lose weight, burn calories, or lose a tummy. You have to burn calories through walking or running or something.
