    Why do my legs hurt after sitting and bouncing on an exercise ball?

    I just got an exercise ball and have been using it to sit at my desk and work and I have noticed that the back of my thighs are sore. Is that normal? Im not trying to lose weight, just get more flexible, so I don't need no ads. Thank you.
