I came across this show, hosted by Mel B (DwtS contestant) about a week ago, thanks to TiVo. I think (as I've only seen the one episode) that premiss of the show is a bunch of people trying to lose weight via a dance competition. The episode TiVo caught was the ballroom round. Eric Mazo was the featured pro. If you catch a rerun, you'll cringe ;-) I've been watching it in bits, but the first couple to dance were supposedly doing a v-waltz, but the music was in 4!
