I have read many posts about the difficulty of the stability ball. (It makes me laugh to think of all of you rolling around on something that is called "stability" ball.) I purchased an hourglass-shaped ball that is great for ball work. It doesn't roll around as much and its contour allows for better ab work. I purchased it from QVC last year and it is a Denise Austin product (the only thing that I have kept from her). I don't know if it is still available, but it might be worth the search.
Have fun.
