The Exercise Ball

I have only used an exercise ball for exercise, but have been considering it at work for sitting at my desk too.  I teach, and don't sit all that much, but when I do, I'm thinking it might be good for me!  I've been reading about how it causes "active sitting", activating back and stomach muscles, and not allowing you to slouch as much as normal desk chairs do.


Some important points:


*to make sure you inflate it to almost maximum capacity so it's actually supportive
*research a high quality ball so it holds up without leaking
*start using your ball in short increments to get used to it safely
