Step-by-Step Execution

Follow these steps to perform the Seiken correctly

  1. Starting with the little finger, bend all four fingers so their tips are digging tightly into the palm as close to their bases as possible

    Photo 1: Fingers curled tightly into palm. This is the foundation of proper fist formation

  2. Bend the thumb over the second joints of the first two fingers (index and middle) to further tighten the fist

    Photo 2: Thumb locked over knuckles. This secures the fist structure and prevents injury

  3. Hold the fist with palm facing up, touching your side on a level with your chest. The arm and back of hand should be in a straight line

    Photo 3: Ready position with fist at hip. This is the correct starting position for Seiken thrust

  4. Thrust forward while turning the fist inward so at the point of attack the palm faces down

    Strike with the knuckles of the first two fingers. Keep arm and back of hand rigidly in a straight line
