A friend, fellow board member, beautiful lady and co-worker of mine, Esther, works each day perched atop one of those large exercise balls. Coincidentally she is the same broad who taught me to knit. Man is she versatile. Anyways, I’ve heard this is very good for you and Esther has mentioned it has improved her posture.
I attempted to sit on an exercise ball at work.
The plan was to sit on it for the last hour or so of work to gather a feel for it. I lasted an unprecedented 4 minutes. I found it noisy and uncomfortable. Perhaps too low to the ground? It was a strange, scary feeling I had while sitting on that ball.
