Query: Great video

It's a great workout video. Makes you sweat in 20 minutes. I like the fact that you can do it for 20 minutes a day or longer if you want. The abs exercise are not that great but after the cardio and strrength, I need that break!I would have liked to skip all the talk in the beginning and get to the exercise quickly but the DVD does not let you do that...Overall - it's a good workout
