it depends what you want to achive. imo just doing crunches does not help. it does not remove the fat around belly area. so cardio is also very important.
I go to curves 4 times a week and I still have my belly, it just won't go. I do sit ups but must not do them regularly enough to make a difference. Any healthy food and exercise is good.
I would think with the crunches and the cardio it will get smaller.To get it to go away a person most have to do alot of floor exercises and be pretty skinny.I know i should aslo be lifting weights too but haven't done that as much as i should too.
how often do you excercise? i had a gym membership card for a month and i had weight trainign twice a week, cardio once and pilates once a week. and lets be honest, i see no difference. i will start again in january if my timetable lets me.
