Have you tried Yourself Fitness? It is also a PS2 game (and PC and maybe XBox) that has an animated instructor, and you follow along with her in over 500 different exercises. I have it, but haven't tested it out yet. Right now I am doing Project: YOU and between that, 3FC, life, and a book, I won't have it penciled in until late May.
It says no two workouts are the same, and it will also customize your meal plan and give you 4500 recipes. Sounds pretty cool!
