So I have been using a body ball at the gym for about 2 months. I love it. I love the range of excercises you can do on it, and then being able to roll out and STRETCH my back on it after a rough set of repititions.
I bought my very own today at Wal-Mart for $9.92!! I was super excited. It even came with an excercise chart for my wall almost identical to the one at the gym.
Now even if I am too lazy to hit the gym, that ball will be staring at me telling me to get my butt up and move!
