7E Spa--Body Contour Machine (losing weight without working out)?

Tweet

The other day I purchased the groupon that is good for three sessions of the body torc contour machine at 7E Spa. Has anyone ever heard of this? There are nothing but good reviews all over the internet and it's guaranteed to help you lose inches every session. I've lost quite a lot of weight this year, but for some reason my back side (lower back, butt, and back of thighs) still look pretty meaty and cellulite-y. I'm going to try this out since I have the Groupon but if anyone has every tried it/knows someone who's tried it post the experience!
