BALANCE DISCS:
I've tried that at our gym..the kind with a 4" black ball at the bottom VERY difficult..even at the "easy" setting.
the 20" accross one thought is a lot of fun.. and very interesting possiblilities with it.(Bosu they call it) either right side up or down. but must be quite expensive. ('bout 100$ ?)
I also tried one that looks like the red balance disc in this picture, best buy I think
