I was wondering, is there any difference between a stability ball and an exercise ball?
What size ball is recommended for someone who is 4'11"?
Any recommended brands? Or tips for buying/using them? Or any suggestions for good workouts or dvds that I could buy to use with them?
I won't be able to buy most kits because they don't have small enough balls, but I'm thinking I can just buy the dvds, like core secrets and others, and just buy my own ball to use. Does this sound like a good idea? I'm new to the whole ball idea, but I really need to work on my core.
