YOGA BALL

I sit on a yoga ball at work most of the time. It helps to strengthen my abdominal muscles. The stronger they are the less my lower back hurt. Today I aired up my ball too much so my thighs are hitting the bottom of my desk & my feet are dangling. LOL I put a tool box for my feet to rest on & am having fun rolling around at my desk. I may get brave & try to let a little air out but not until I have a little more fun. I love bouncing to music on it. :)
