I recently got one from Netflix, Jillian Michael: Banish Fat, Boost Metabolism (http://www.amazon.com/Jillian-Michaels-Banish-Boost-Metabolism/dp/B001NFNFN0/ref=sr_1_1?ie=UTF8&s=dvd&qid=1259459536&sr=1-1). Sounds pretty good, right? I tried it for the first time tonight. It is awesome. It totally kicked my ass, in a good way :) It keeps you moving constantly without concentrating on any one area for too long. My only problem was there was a lot of jumping, which is difficult to do in my 100 yr old townhouse without annoying the hell out of the neighbors. Jillian Michael (of Biggest Loser fame) has several other videos that I'm excited to try.
