what's a guym?

In my efforts to become more healthy and in shape, I've done something I vowed I would never do. (At least, not again.) I've joined a gym. Yes, after seven years of being "not a gym person," I've purchased a Goodlife membership. I think my decision came partially from my desire to look better, and partially from my brother telling me that I should join the gym and get stronger.

It's bizarre to me that I'm now one of those people that "goes to the gym" after work, or says "I'm off to work out," to others.

Even more odd: I actually like exercising. I've been doing a combination of cardio/weight training, and find that I enjoy every aspect of it. I'm even considering trying some of the classes they're offering.

What's happening to me? I'm not the person I used to be!!
