The thumb and index finger is shaped into that of holding a cup. This puts your hand in a good position for blocking and striking. It also keeps your hand and arm ready for a wide variety of techniques, and makes the shoulders ready for explosive movements. The wrist is in a position where it can easily strike or block, and the fingers are curled in, which helps in trapping an opponent's arms while blocking. The arms can be used for short or long range techniques combined with various feints and strikes.
