Query: Lots of Fun

Tones up the mid-section fast! I'm no dancer but I was able to follow this fairly easily - step guide helps. The more I do it, the more fun it gets because you can get "deeper" into the moves. There are workouts that burn more calories but this one is a great energizer. I work out at 5 AM and I actually look forward to getting up to do this workout.
