Crossfit?

This week I'm making kind of a weird goal (#47) and that is to go check out the CrossFit gym downtown before February of next year. I am simultaneously intrigued and wary of CrossFit- most of the people I know who do CrossFit are in excellent shape and talk about how much they loooovvvveee CrossFit. I have also met a fair number of people who have gotten injured doing CrossFit, and that is part of what makes me wary.  I've also have gotten the impression that CrossFit gyms can be a little competitive, and as I think I've said before, competitiveness in gyms is something that isn't really a good fit for me. But recently a customer at the Co-op who I really like told me that the downtown CrossFit gym has a beginner program where you learn to do the exercises with other folks who have never done CrossFit before. He claims it's low-pressure, fun, and fairly affordable. I figure it's at least worth checking out and might be a way to keep myself motivated and interested in working out.
