Hate it. I went in, you basically go in a circle and use each machine. If someone is ahead of you and slower you have to stand and wait. You can't take time and do it longer or shorter.
I also had severe pain after using the machines one time during a free trial visit. The exercises were not a good fit for my disk injuries. There was also no one on one help avail due to them working with one or two of the regulars.
I got much better results from a regular place like Mademoiselle. I went to the one is OKC. It's for women only and is like a regular men's gym where you can go do free weights, tables, they offer different classes like Zumba or aerobics, it is much more suitable to me since I like a variety.
It does take a bit more time but I just have to finish off with a dip in the pool. Or the hot tub.
Here is a link to the one I used to be a member of when I lived on that side of town. It might give you some ideas of what to look for in a gym program to make sure it is the right one for you.

Our local YMCA has almost every thing they offer in this place too. They have the pool exercise classes, Zumba, classes for older people, high impact and low impact, all kinds. If you don't have other options it's worth calling the Y to see what they have to offer you too.
