I got a new stability ball and reisistance bands yesterday.  I got he ball blown up and streached my back out. That is was just as good as going to the Chiropracters.  I had one in Utah but gave it to a friend becuase it wasn't one of the things we had room for at my mom's house. NOw that we have our own place and not a closet I got a new one. I can't believe how much I missed doing the exercises. 

This is the one that I have.
