I have many DVD's on qigong (chi kung) and t'ai chi. This DVD is the worst. It does not even mention, much less cover qi (chi), which of course is what qigong is all about...cultivation and direction of the universal force. The instructor does not even discuss breathing techniques, which are essential in cultivation and direction of chi. The DVD consists of a handful of mobility exercises, i.e., opening the waist, sacrum, back, shoulders, knees, etc....that's it! Thank God I only rented this, instead of buying.
