I want to get a new step aerobics dvd and I came across this one, "Shapely Girl: Let's Get Stepping with Debra Mazda - Beginner Step Cardio Workout". Has anyone done this workout or any of her other ones? I am using Cathe Friedrich basic step right now and I love it. but I want to have a bit of variety too. I hate to spend the money on a dud and thought you guys were the best ones to ask
