Purpose

The most reliable kimura defence at the Developing level is gripping the far leg — the opponent clasps their own thigh or shin with the free hand, creating the secondary anchor that prevents the rotation from completing (control the secondary anchor). Most practitioners respond to this anchor by forcing harder on the submission. The correct response is to read the anchor as a signal that the back is available.

This drill isolates that reading: when the anchor appears, the attacker immediately initiates the back-take sequence rather than continuing the rotation attempt.

Constraint: The partner’s only defence is gripping their own near or far leg. No frames, no bridging, no counter-attacks. The attacker has exactly one job: detect the anchor and initiate back entry.

Setup

Top player in side control with the figure-four loop established, at approximately 60–70% rotation. At the start of each rep, the partner grips their own near thigh or far shin with their free hand — the anchor is pre-set, not reactive. The attacker begins from this state.

Execution

Reading the anchor: The attacker confirms the anchor is present by applying a brief test rotation. When the rotation stalls, the test is complete. Do not force.

Step 1 — clear the near hip: Release the hip-lever position and step over the partner’s near hip with the near leg. The figure-four grip is maintained throughout.

Step 2 — drive into turtle: Apply steady pressure through the grip to roll the partner toward their opposite side. The grip remains intact as the partner comes to their knees (turtles) or begins rolling.

Step 3 — establish chest-to-back connection: Once the partner is on their side or in turtle, establish chest-to-back contact and build toward the seatbelt. The figure-four grip can be maintained as an initial control before transitioning to the seatbelt.

Complete five reps per side. Each rep ends when the attacker has established chest-to-back contact with a seatbelt frame or has the partner clearly facing away in a back-take position.

Coaching Notes

This drill trains what is arguably the most important single decision in the kimura system: the moment the attacker stops trying to finish the submission and starts using the grip as a back-take lever. The practitioner who cannot make this decision in real time has a one-dimensional kimura that experienced opponents will simply shut down by gripping their leg.

The drill deliberately pre-sets the anchor so the attacker starts from the correct decision point without needing to earn it first. This trains the response pattern before it needs to be recognised live.

The timing of the hip step (Step 1) is the critical variable. Students tend to step too early (before the grip is driving the shoulder into the rotation that forces the turtle) or too late (they have abandoned the rotation entirely and given the partner time to recover structure). The correct moment is when the rotation is applying enough pressure that the partner is beginning to yield sideways rather than holding purely static.

Common Errors

Forcing the rotation instead of reading the anchor: The anchor is a decision signal, not an obstacle to overcome. Students who force harder on a blocked rotation are spending energy correctly applied to the back take. Cue: “if it stalls, go back.”

Releasing the grip during the step: The figure-four grip is the handle that controls the roll direction. Releasing it during the hip step removes the control and the partner can sprawl back to top position. Require grip maintenance until chest-to-back contact is achieved.

Stepping over rather than around the hip: The step that clears the near hip should go over — not in front of — the partner’s hip. A forward step crowds the attacker and makes the roll direction ambiguous.

Partner re-gripping during the roll: Some partners will attempt to re-anchor during the roll. The constraint is that they may only maintain their initial anchor, not add new anchors. If this happens, re-read the constraint before continuing.
