What makes Volume One of this series such a great investment is that it's as though you're right there in a Qi Gong class/session with Shifu himself, so you're not only learning the movements, but you're doing the Qi Gong right along with him. Many of the movements end in postures that need to be held for three breaths. In Volume One, Shifu takes these additional breaths, allowing you time to do so as well, so you can practise and learn the technique all at the same time. Fantastic. It's like having a master Qi Gong instructor right there in your living room. Well worth the investment. Unfortunately, he abandons this method in Volumes Two and Three, so you cannot follow along with him. Buy this one. Be cautious about the other two.
