Patient discussion about crunch

Q. If your stomach muscles are cut across(bikini-cut from a c-section) does that mean that situps(crunches) won't do any good? Is there a better way in this case?

A. from what i know- it's not very good to do any sport right after a c-section. but you should resume as soon as you've been cleared by your doctor to help restore your strength and pre-pregnancy body, and then there is no problem to do situps.
