Gyms

When I first got married I worked out twice a day once at the gym and then I'd go running down to the beach everyday. What the life, then we moved away from the beach and had our first kid. I then would work out 4 times a week. Which is what I've been doing since my first kid. I stopped our gym membership and work out at home, mostly running, since I enjoy it. I bought a treadmill and then I even won a treadmill and a home gym on the radio so I didn't really need a gym membership. Even though I work out faithfully it doesn't seem to matter how much I work out, there has been no loosing or gaining weight going on here in the last 4 years! What is the deal? I need to go back to working out everyday 2 times a day but with 3 kids, a house to keep and a husband there is no possible way! So I heard a thing on the radio about this gym offering no fees to sign up, free tanning, free kids care, 2 free sessions with a personal trainer, it is right down the street from my house and all for a low monthly payment. This morning I made an appointment and went to check it out. It is nice and they do offer a lot of cool things but my question is, why did I come out of there with $132.00 less in my bank account? Didn't they say it was all pretty much free? I am a sucker!
