Hammerfist strike using the bottom of the fist

TechniqueStrikesBeginnerKarate

Key steps

  1. Form a tight fist and angle the bottom of the fist so the hammer surface can land cleanly.
  2. Drive the strike with the hips and shoulder connection rather than just dropping the arm from the shoulder joint.
  3. Keep the elbow slightly bent and the striking path compact so the hammerfist stays heavy and controlled.
  4. Recover the hand back to guard or chamber quickly and re-establish your balance before the next technique.

Coaching points

  • Stay relaxed until the moment of impact.
  • Let the hips and stance support the strike.
  • Recover quickly so the next action can flow.
