This was the WORST tape I've ever gotten! The Tae Bo Live Series and original Advanced tape are far better workouts and more comprehensive than this. I agree that the double-time is way too fast and you simply don't get a workout from this.Tracy is terrible. She is annoying, her moves are basic and boring (think beginner's jazz class with box steps and grapevines). I do not recommend this to anyone looking for a good workout.Stick with TAE BO!!
