Have any of you tried sitting on one while at working/at the computer?
Yesterday I walked past someone kneeling in his chair and he told me that his back hurt and he was considering bringing in an exercise ball to sit on. I reminded him we had one downstairs in the gym and he went and got it and tried it out. I'm trying to today and I"m having fun! I'd never heard of the idea before, but when I googled it there's a lot of talk about it, although most of it seems to be about 5 years old.
Any thoughts?
