At the risk of stating the obvious, these balls are great for physical therapy as well. But you have to make sure to get the correct size, which is based on your height.

I am 5'2" and I purchased a 55cm ball to use as a chair for work.
I should have gone for the 65cm ball, but I was on the cusp and figured it would be too tall. It would have been perfect.
