Yesterday, with some trepidation I acquired an exercise ball. What is that rule?
If it seems to easy, it is too easy.
Well, what could be easier than sitting on a ball, writing and getting core strength all at the same time. I know, I know - too easy. Or maybe you're asking what's core strength. I won't get into it in this post - a google of exercise balls will tell you everything you ever wanted to know. In the meantime, my office now has what looks like a giant beach ball.
Surprisingly, other than feeling rather silly, it's fairly comfortable. What it will do - if it doesn't deflate first, time will tell.
