From the many sets of qigong exercises, this one presented by Dr.Lam is simple, yet very powreful. It can be done from every group of people, beginners or advanced, not necessarily fit people. Dr Lam teaches in a very clear way five qigong movements and he gives clues of what to experience. You are going to sense qi moving in your body in a very short time. There are two demos of the complete set. One full round takes 5 minutes, it is up to you to increase the length.
