Hi I am glad I found this thread. I have been going to curves since April of this year, and I love it. I only go 3 times a week and spend 30 min on their machines and a few minutes stretching. I have fibromyalgia, thought that it would effect it for the worse, but so far my muscles are alot more limber and my stamina is much improved. I haven't got measured in a few months. But the last time they measured me. I had lost 3 inches of my waist, I was impressed. And what I like about it is I don't feel like I am beating myself all up. you go at your pace.
