Free 8-week Ballys pass

Hi everyone, I kept meaning to post this and now it's almost too late.. i know a lot of you have gym memberships already but for those of you, like me, who don't, the discovery channel is having this national fitness challenge thing and if you register for it (registration is free), you get a free 8-week membership pass to Ballys. When I was heavier, I was always a little (ok, a LOT) intimidated to go to a gym (yes, I know this is crazy but it's how I felt!) so I never joined one. Now, I'm considering it but this seemed like a good way to really get a feel for it and it's a long enough pass to make sure I'd really go and whatnot... Anyway, there's information about the fitness challenge (which I'm not really doing anything with) on health.discovery.com if anyone's interested.
