I hate Taebo. But that's coz the punching movement makes my wrist hurt.
Carmen Electra's Aerobic Striptease is OK, but very boring. When they teach it you, you repeat everything 50 million times. And it didn't feel like it was doing anything.
Mr Motivator is really great. He tells you how long to do it for if you're a beginner, intermediate or advanced. And he has ideas on sensible diet tips too. However, the dodgy lycra clothes are off putting.
I have one called Callenetics or something, and that is very boring. And you need a dance studio with a barre.
Pump It Up is my favourite. It has different sections, so you can miss a few out to start off, and then when you get better you can do more. They're not hard moves (except that "pony". I don't get that!) but you do a lot of them and fast so you get results.
