Seiken-choku-zuki

(straight punch). Starting palm upward from a point just above the waist, the attacking fist is thrust straight outwards, twisting as it nears the target so that the palm is downward at the moment of impact. Simultaneously, the other fist is withdrawn sharply to the corresponding starting position, the reaction of this movement adding to the momentum of the attack. As with all the hand techniques, the muscles of arm, back and chest are momentarily tensed at impact, and then relaxed in preparation for the next technique. At no time should the shoulders be hunched.
