agreed! I love the balance ball! It gave me a way to stretch my tail bone, and spine! ooooh, that felt so good! I have a pilates machine that does wonders as well for deep stretches. I found in the end after spending money on all kinds of machines, and gadgets the best one by far has been the Wii. its fun, its active, it keeps your mind engaged. Past that, its a walk that keeps me moving. Each day I try to go a step or two further. I have found that since increasing my stamina, I have found doing my inside stuff a bit easier.
