I have the Carmen Elektra aerobic striptease DVD (volume 1). I really like it--it's fun and easy to do. However, after learning the routine the workout gets too easy. I'm going to buy the harder DVDs so I can get a better workout.
I also own the Lotte Berk method videos (hiphugger abs, high round assets, muscle eats fat, and the basic intro tape). I love doing the hiphugger abs and muscle eats fat. High round assets gets a little boring for me and after the first time I didn't really need the intro tape.
The other one I have is a basic yoga DVD that is targeted for evening stress relief. I figured I'd try it out for the nights when I don't feel like doing much but just want to relieve stress and get some stretching done. It's good for that.
I bought all of mine on overstock.com because they're a lot cheaper. Sometimes they take awhile to deliver, though.
I dont have a recommendation, but i want to start doing one too. I actually saw some video on an informmercial a couple of days ago and i can't remember the name of it! It's kinda like yoga booty ballet, but more intense (and no ballet). It uses some "11 basic moves" that incorporates dancing and kickboxing into some routines or something. It kept talking about how the music is awesome....the video seemed really good but i can't find it anywhere! does anyone know what it might be??
