Even though I'm not a CE I am responding with a review on this subject. My daughter and I decided we needed to do something that we could do together, close to home and at our own pace. We just recently joined Slim and Tone, very much like Curves. It is not horribly strenoues on ones body like I thought it would be. You have a variety of hydraulic machines and bounce pads, plus tread mills, bikes and more. The thing I like best about it, only women go there .. no men. You work out for approximately 30 minutes per session. We already feel the difference.
