Core Strength, or just pain?

Feeling virtuous and ambitious one day last week, I ordered the Gaiam BalanceBall Chair, which is supposed to strengthen my core muscles and improve spinal alignment while I work. Sounds brilliant, right?

It's definitely better than just sitting on a plain old exercise ball at my desk, since that thing was always getting in my way and I could just never get it to the right height.

I can already feel it in my "core," but I can also feel it in my neck a little bit. Hmmm ... I think I may need to tweak the ball inflation a little bit.

Keeping healthy and fit seems to be a full-time job with a lot of requirements!
