How much calories are burned by crunches?

Question

i realize that significant calories are burned after 10 minutes of crunches. im capable of doing 10 minutes of them [going to keep exercising til i can do more] so was wondering how much they burn. please and thank you.

Answer 1

It's more than 3-3 1/2 per minute. You burn more by BREATHING (yup. it's true). Anyway, I wouldn't suggest doing crunches if you are trying to lose weight (sounds like it?). Crunches just build muscle under fat. They don't actually do anything ABOUT the fat.

Answer 2

It's your heart rate that burns calories (read about it).  Keep the heart rate up for 20 mins at least.

Answer 3

about 3 to 3 1/2  a minute.
