I've belonged to gyms off-and-on but found I prefer to run outdoors around my own 'hood and I just use push-ups and free weights at home for the rest. Even when there was a free military gym just blocks from my house, I didn't go there very often. You don't need to worry though--there are lots more out-of-shape folks who are "working on it" than hot folks in most gyms. Unless, of course, you join a high-priced, snooty gym where they network as much as workout.

My cousin joined Gold's Gym a couple of months ago and she got me a free pass for a week. I was a little nervous going into it, but I am glad I did it. I am not overweight but I am not as thin as I would like to be. To my surprise everybody in there (besides the handfull of skinny girls) was in the same boat I was in. I got a kick outta watching the skinny people watch themselves in the mirrored wall while they worked out. I saw a few people that I knew (that sexy waiter from Applebee's has biceps that'll make you melt) and I thought I would be embarassed, but I wasn't. I think it helped that I had a partner-in-crime. She motivated me when I was sore from lifting weights and applauded me when I lost 5 pounds. I say go for it.
