I refuse to pay for the gym. They are available, but I don't know anyone that uses them regularly. The fee is not that cheap and I figure that I pay enough to park now, that I'm not going to be giving back even more of my paycheck for equipment that is already there and paid for.
I tried a health initiative program and my main goal was to have someone show me the proper settings for the machines. They didn't. I complained that I wasn't given the service I was promised as part of the wellness program, but they insisted that I needed to pay for a private trainer (stud muffin, jock, rep counter) to actually show me how to properly use the equipment. I refused and haven't been back since.
If I want to join a gym, there is a Gold's about a mile from my house. However, I went for a tour, and they wanted me to sign a waiver of liability. I refused that too. I have no idea what may be in there, or what liability I may be signing away! After all, Sears doesn't make me sign a waiver to look at the lawnmowers! What is so dangerous in there that they require a waiver to look at?
Mostly I walk for exercise (though I sprained my ankle over 2 weeks ago and it still hurts and swells... and has pretty colors on it now).
