the turbo jam workouts, My wife will be starting this in early january, anyone have any results with this workout?

I've watch the video, the lady runs a pretty intense class, looks decent. Just want to know if anyone has had a positive result from this workout regime?

Love it! The music is really great, and I love all of the members in the class. On another website a group of people who do the workouts have had really good results- definitely worth it!
