Query: Good Workout Video

The video is very good- I have only been using it for a three weeks now. The instructor is very positive and energetic and can be fast paced at times explain work out series. Luckily- I have a dance background and have been able to follow along pretty well. I would highly recommend this product to anyone that wants to get an AB or Cardio workout.
