In this clip UK Head instructor Aaron Baum Sifu is training Chi Sao with Sam. You can see how when two people have solid skills and no ego, they can practice together with flow and controlled power. Chi Sao is not about trying to hit someone in the face. Strikes should be controlled but have power within them. It is about the timing, balance control, flow of applications and feeling of your opponent’s structure. This is an excellent example of how in a short roll you can apply and develop so many layers of skill in a very safe but live format.
