Hip Lever Positioning for Kimura Force

Elevated Risk This drill loads joints at competitive intensity. Run only with practitioners experienced in the relevant submission and at communication pace.

The person applying the technique is responsible for releasing immediately.

Communicate before drilling. Know your partner's experience level with this position.

Do not train this technique while fatigued or in live rolling without established mat culture.

The kimura submission does not operate on arm strength alone — it requires the attacker’s hip to be positioned as a mechanical lever that forces the shoulder into internal rotation. Students who rely on pure pulling force generate a tug-of-war they will lose against larger or stronger partners. Students who understand the hip-lever geometry can apply the submission with minimal strength because the load is transferred into the skeletal structure rather than the muscles.

This drill trains three hip positions and the different rotation arcs they produce, using a cooperative partner so the attacker can feel the mechanical output of each position without applying dangerous force.

Safety note: This drill works to the edge of shoulder rotation only — not through it. The partner taps at the first sign of joint tension. The purpose is positioning, not finishing.

Top player has the figure-four loop correctly closed from side control (see DRILL-KIM-01 for grip entry). Partner lies passive with the near arm trapped in the loop. The bottom player does not resist and taps immediately if any shoulder discomfort is felt.

Position A — hip behind the elbow: Top player walks their hips toward the partner’s head until the hip is directly behind (posterior to) the trapped elbow. From here, begin rotating the grip slowly and feel where the load sits in the shoulder.

Position B — hip at the shoulder line: Top player walks back until their hip is level with the partner’s shoulder. Repeat the slow rotation and compare the load point.

Position C — hip toward the torso: Top player places their hip on the partner’s near hip. Repeat and compare.
