Picked it up today; I can already feel the difference.
I'm looking forward to the end of the school year. It's not the kids (well, they HAVE been a little squirrelly lately - Seniors). But, I really need the less structured time in the summer to heal my arthritic knee. I'm looking forward to being able to swim daily, have the time I need to do my PT exercises, and just catch up on household stuff.
With hard work, I may finally be able to lose the weight I've gained over the last several years.
