Also called Straight knee, Clinch knee, Khao

The straight knee drives the knee forward and up into the opponent's body, powered by thrusting the hips. It is the main weapon of the Muay Thai clinch, where the opponent's head is held, and a strong answer to an opponent who rushes in. Repeated knees to the body drain stamina quickly.

Coach demo coming soon

Satori's coaches are filming every technique, full speed and slow motion from two angles. Until it's up, the diagram shows the movement step by step.

How to do it

  1. 1Control the head or arms, or step in behind a punch, to close the distance.
  2. 2Rise onto the ball of the standing foot.
  3. 3Drive the hips forward as the knee comes up, pointing the knee at the target.
  4. 4Point the toes down, and in the clinch pull the opponent onto the knee.
  5. 5Lean back slightly for balance, then return the foot to stance.
Common mistakes
  • Lifting the knee without pushing the hips, so the strike has no weight.
  • Leaning forward over the knee and losing posture.
  • Staying flat on the supporting foot, which shortens the strike and slows recovery.

Safety: Knee the pad or belly protector only, never an unprotected partner, and keep knees off the head in all partner drills.

Drills

Drill it

Your partner holds a belly pad or kick shield; take a light plum and deliver alternating straight knees for 30 seconds, then switch.
