I joined Curves last week -- more so that I can be healthy and get some exercise than anything else. I dont know about your area, but right now they have a deal on (i'm sure theres always a deal on ) for 30% off initiation, and first month free. I'm happy with it since its just a circuit, and the people have been really friendly. I was a member of another gym, and it always made me self concious there - and I dont feel that way at curves.

In a lot of curves places, if yuo ask for a 2-week free trial to see if you like it, they will usually give that to you

Also, I had a friend on weightwatchers, and she really liked it a lot. I haven't tried either, so I can't really give a good assessment
