How to Perform
- Stand in a stable stance with one fist extended and the other at the hip, palm up.
- Drive the rear fist forward along a straight line towards the target.
- Rotate the forearm so the fist finishes palm down at the moment of contact.
- Withdraw the other hand sharply to the hip at the same speed, using the hikite pull.
Coaching Cues
- “Both hands move at the same time.”
- “Rotate the fist late, just before impact.”
- “Punch from the hip, along the centre line.”
Common Mistakes
- Rotating the fist too early, which reduces acceleration at impact.
- Neglecting the withdrawing hand, which removes the counter-rotation.
