I personally love the Adductor & Abductor Machines. They don't "shrink" my legs, but I definitely feel as if they have made my legs stronger. And if nothing else they've made me more flexible. The one at the gym I go to, I used to only be able to spread my legs to a 5, and after a month on it I can spread to a 6. So I think if nothing else I'm regaining my flexibility that I've lost over the past few years.
I go to Fitzone now [used to go to YMCA], which is kind of like a Curves. What I'm doing must be working because I lost 5.5 inches in my first month!
Those were the only ones on the list that I do.
