Qi in Kung Fu
All schools of martial art have some kind of internal work with qi. It is the qi that is the “secret of kung fu”. Some believe high level students only have the privilege to learn because it can be used to harm others. Others believe it is a right to teach beginners because it is good for all around physical, psychological, and spiritual well being. At the Wei Tuo Academy, it is one of the first things students learn.
Qi in the martial arts is what helps protect a person from injury and also heal from an injury in less time. To learn how to use qi, one must learn Qi Gong.
The video is interesting, but do not try without supervision of a qualified master.
