While this will give your booty and legs a workout, I was disappointed on two counts. One is the music -- there is no discernible melody, and the drums (?) are tediously repetitive. I need to be motivated by music when I workout, so I was dreading the idea of doing this workout again. I've decided to find a suitable music CD, and play it simultaneously with the silenced DVD. The other disappointment for me is the videographer's choice of focus. Many times he/she focuses on the face, chest, or upper arms of the instructor, when the action is all going on in the legs. It's extremely frustrating to try to follow along when I can't see the moves! I find this inexcusable in what is supposed to be an instructional video.
