This is a decent exercise video. The issues I have with it is the production decisions to be cutting edge with their video effects and constantly moving camera. I found both to be distracting from my ability to mimic their movements. In addition, the explanation of how to hold the feet, and the reasons could have been better. It was good to have a second student; perhaps separate audio tracks could have been used to better separate the beginner and more advanced section. The disk I rented had the bonus 14 minute energy workout, which was quite good, though it is best done by those at the intermediate level. I also found the running time a bit confusing. The total length of video was different enough from totaling each of the chapters that I'm not sure what they considered the total.
