Meet Dk Yoo, a Korean martial artist who has trained in 15 different martial arts. He has taken the best of each art and learned how to take full advantage of his body mechanics. In martial arts, the most important skill is knowing how to transfer energy. The transfer of energy is where the power comes from.
While the partners he’s demonstrating on are a bit exaggerated with their motions, it does not take away the guys speed and technique. The technique and the speed of his strikes are enough to take down most untrained opponents.
