In this clip we look at the arm that rises during the bil gee garn sau. Starting from the end of the downward movement and then transitioning to up gave a better sense of the purpose and shape of this arm. Sigung corrected me so that the forearm had a slight curve which focussed the force more clearly. It reminded me of curved mirror focussing light. My mistake had been to apply the arm straight so it was attacking like a stick. Sigung’s correction which you can see in the clip gave me much more control of the opponent’s arm and the refined focus attacked the opponents balance more efficiently. Next week we will look at the relationship between the two arms and how they complement each other.
