What's the best gym or fitness center in Pueblo?

The college (CSU-Pueblo) actually has a fantastic rec center, and it's open to the public. Membership is $50 a month ($60 if you sign up with a partner), and it includes access to all the gym equipment, aerobics classes, the pool, and the rock well.

If you don't want to be surrounded by college students, I'd try the World Gym on Eagleridge. I don't think they have a climbing wall, but they do have a private women's fitness center, which I found pretty great.
