The principles of Tang Soo Do techniques are based on the design of the human body. For power the body develops the larger, powerful muscles of the torso. The speed of the techniques comes from the fast, agile muscles of the arms and legs. As students progress in Tang Soo Do, they learn to coordinate this speed and power, and develop a concentration to focus all of their body's strength into a small, hard striking surface like the edge of the hand or the heel of a foot.
