I've never heard of it, but I went to the site. It's another money maker for them. I didn't sign up, but the exercise is only 15-18 minutes twice a week, I know this wouldn't work. It's not enough time to do anything, by the time your day comes around to work out, you've lost all that you gained in that few minutes. Their work out routine is a joke, don't know about the rest.
It looks like it's just for one person and you fill out a form and they'll know if you're a woman and a man.
