Question about sit-ups?


Which is better to do sit ups on? A blanket laid across my carpet. Or an excercise ball. Also how many should I do daily?
Best answer:
on an exercise ball because you will feel more of a burn which means your streching more muscles with is better..

um .... do as many as you can handle!
