SAFETY: Kimura from Kimura Trap targets the Shoulder joint (glenohumeral) and elbow. Risk: Shoulder dislocation (glenohumeral subluxation or full anterior dislocation). Release immediately upon tap.
Executing the Kimura from Kimura Trap requires mastering the transition from positional control to active submission finishing. The attacker must recognize the precise moment when the opponent’s defensive structure has deteriorated enough to begin the finishing sequence—attempting too early against intact defenses wastes energy and may compromise the grip. The process involves creating the proper finishing angle by walking feet toward the opponent’s head in an arc, generating rotational force through hip positioning and body mechanics rather than arm strength alone, and maintaining heavy chest pressure throughout to prevent the opponent from creating escape space or rolling out of the submission. The key distinction from standard Kimura finishes is that the Kimura Trap system provides superior grip depth, sustained control, and multiple layers of positional dominance that enable a methodical, high-percentage finishing approach where the opponent’s defensive options are systematically eliminated before the final rotational pressure is applied.

Key Attacking Principles
- Verify deep figure-four grip positioning near the opponent’s elbow before committing to the finish—shallow grips near the wrist lack sufficient leverage
- Create the finishing angle by walking feet in an arc toward the opponent’s head rather than attempting to finish from a squared-up position
- Generate rotational force through hip positioning, body weight transfer, and chest pressure rather than relying on arm strength to crank the submission
- Maintain heavy chest pressure throughout the entire finishing sequence to prevent the opponent from posturing, bridging, or creating escape space
- Break defensive grips systematically before applying final rotational pressure rather than trying to power through clasped hands
- Apply the finish with slow progressive pressure in a smooth arc motion, never jerking or spiking the arm behind the opponent’s back
Prerequisites
- Deep figure-four Kimura grip established near the opponent’s elbow with secure wrist-on-wrist or wrist-on-forearm connection
- Chest pressure pinning the opponent’s upper body to the mat with hips low and heavy
- Opponent’s defensive grips neutralized or weakened to the point where rotational force can overcome remaining resistance
- Finishing angle created with feet walked toward opponent’s head, establishing perpendicular body positioning for maximum leverage
- Opponent’s far-side arm controlled or neutralized to prevent frames that could create escape space during the finish
Execution Steps
- Consolidate Kimura Grip Depth: Verify your figure-four grip is positioned deep near the opponent’s elbow, not their wrist. Tighten the lock by squeezing your elbows together toward your centerline and ensuring your wrist grip is secure. The gripping hand should control their wrist with a firm thumb-in configuration while your other hand wraps your own wrist. (Timing: 2-3 seconds to verify and adjust grip before proceeding)
- Establish Heavy Chest Pressure: Drive your shoulder and chest weight downward into the opponent’s upper torso, pinning their shoulders to the mat. Your hips should be low and sprawled with weight distributed through your chest rather than resting on your knees. This pressure prevents the opponent from bridging, creating space, or generating the explosive movement needed to escape. (Timing: Continuous throughout the entire finishing sequence)
- Create Finishing Angle: Walk your feet in a gradual arc toward the opponent’s head while maintaining chest contact. Each small step increases the angle between your body and theirs, creating greater mechanical advantage on their shoulder joint. The goal is to achieve a roughly perpendicular position where your body is angled across their torso at approximately ninety degrees. (Timing: 5-8 seconds of progressive angle adjustment with small deliberate steps)
- Break Defensive Grips: If the opponent has clasped their hands together or grabbed their own clothing to prevent arm rotation, use systematic grip-breaking techniques. Insert your knee between their clasped hands, use your free hand to peel their top hand, or apply a stepover with your leg to create separation. Never attempt to power through a strong defensive grip without breaking it first. (Timing: 3-10 seconds depending on grip strength and defensive commitment)
- Initiate Arm Rotation: Begin driving the opponent’s trapped wrist away from their body and toward the mat behind their back in a smooth arc motion. Use your hip rotation and body weight to generate the force rather than pulling with your arms alone. Keep your elbows squeezed tight and let the figure-four structure transfer your body’s rotational energy into the shoulder lock. (Timing: Slow and progressive over 3-5 seconds—never explosive or jerking)
- Paint Hand Behind Back: Continue the arc motion driving the opponent’s hand behind their back and below their waistline. The arc should follow a path that takes the hand outward from their body, then backward and downward behind their back. Maintain chest pressure to prevent them from rolling to relieve the shoulder pressure as the rotational force increases. (Timing: 3-5 seconds of controlled progressive rotation)
- Apply Progressive Finishing Pressure: Increase rotational pressure gradually as the opponent’s hand moves further behind their back. The shoulder joint approaches its mechanical limit as the wrist passes the hip line. Listen and watch for tap signals throughout this phase. The finish should feel like slowly tightening a vice rather than an explosive crank. Maintain position to hold the submission if the opponent does not tap immediately. (Timing: 2-4 seconds of progressive pressure increase until tap)

Opponent Defenses
- Opponent clasps hands together using gable grip or S-grip to prevent arm rotation (Effectiveness: High) - Your Response: Use systematic grip breaks: insert knee between their hands, peel top hand with your free hand, or apply stepover pressure. If grip persists, walk angle further toward their head to increase baseline shoulder pressure even without rotation. → Leads to Kimura Trap
- Opponent straightens trapped arm and attempts to extract from figure-four grip (Effectiveness: Medium) - Your Response: Maintain wrist control and immediately switch to armbar by swinging your leg over their face while keeping the wrist trapped. Their straightened arm actually facilitates the armbar transition. If armbar is not available, re-bend the arm and re-establish figure-four depth. → Leads to Half Guard
- Opponent bridges and rolls toward the Kimura side to relieve shoulder pressure and create scramble (Effectiveness: Medium) - Your Response: Follow their roll by maintaining the Kimura grip and transitioning to back control as they expose their back. Use their rolling momentum to swing your top leg over and establish hooks. The grip ensures offensive threat throughout the transition. → Leads to Kimura Trap
- Opponent tucks elbow extremely tight to their ribcage preventing any finishing angle development (Effectiveness: High) - Your Response: Walk feet further toward their head to create an even sharper angle that gradually pries the elbow away from the body. Alternatively, transition to north-south position where the different leverage angle often opens the elbow. Use the Kimura threat to advance position to mount if the finish stalls. → Leads to Kimura Trap
Test Your Knowledge
Q1: What is the primary anatomical structure attacked by the Kimura from Kimura Trap? A: The primary target is the glenohumeral shoulder joint, attacked through forced external rotation and abduction of the humerus. The figure-four grip generates rotational torque that exceeds the shoulder’s natural range of motion, threatening dislocation of the humeral head from the glenoid fossa. Secondary stress is applied to the elbow’s medial collateral ligament when the arm is bent during rotation.
Q2: What are the key indicators that your opponent’s shoulder is approaching the mechanical limit during the Kimura finish? [SAFETY-CRITICAL] A: Primary indicators include involuntary facial grimacing, verbal distress signals, the opponent’s body beginning to rotate involuntarily toward the direction of pressure, and visible strain in the shoulder musculature. The trapped arm begins to move more freely as soft tissue resistance decreases near the structural limit. You must release before reaching actual failure—the tap should come well before the breaking point, and you must apply pressure slowly enough to allow it.
Q3: What control must be established before transitioning from Kimura Trap position to the active finishing sequence? A: Before attempting the finish, verify deep figure-four grip near the opponent’s elbow, heavy chest pressure pinning their upper body, a cleared finishing angle with feet walked toward the opponent’s head, and the opponent’s defensive grips broken or significantly weakened. Attempting the finish without all prerequisites established results in a low-percentage attempt that wastes energy and often allows the opponent to escape or counter.
Q4: At what point during the Kimura finish does the opponent lose the ability to effectively defend through muscular resistance alone? A: The critical threshold occurs when the opponent’s hand is driven past the plane of their own back with the elbow pinned close to their torso. Once the wrist crosses behind the hip line while the attacker maintains chest pressure and perpendicular angle, the mechanical disadvantage becomes too severe for muscular defense alone to prevent the finish. Before this point, grip defense and positional movement remain viable defensive options for the opponent.
Q5: Your opponent begins to posture up and create space during your Kimura finish attempt—what adjustment prevents escape? A: Immediately drive your chest pressure downward while pulling the Kimura grip tight against your own torso. Walk your feet closer to create a tighter angle that restricts their ability to posture. If they create significant space, abandon the immediate finish and re-consolidate the Kimura Trap position by resettling weight and pulling their arm across your chest. The grip must be maintained throughout—never release it to chase the posture.
Q6: How should you adjust your grip during the finishing sequence if your opponent’s arm is slippery from sweat? A: Switch from a standard wrist-on-wrist grip to a deeper figure-four where your hand wraps around your own forearm rather than just gripping the wrist, creating a larger contact surface that resists slipping. Additionally, squeeze your elbows together to create compression that locks the configuration in place regardless of friction. In no-gi, the monkey grip with thumbless configuration on the opponent’s wrist provides the most secure connection.
Q7: Why is it critical to apply the Kimura finish with slow progressive pressure rather than explosive jerking force? [SAFETY-CRITICAL] A: The shoulder joint is highly susceptible to catastrophic injury from sudden rotational force. Explosive application can cause full dislocation, labral tears, or rotator cuff ruptures before the opponent has time to recognize the danger and tap. Progressive pressure allows the defender to feel the submission developing and submit safely. In training, slow application develops superior technique while preventing injuries that can sideline training partners for many months.
Q8: What is the optimal competition strategy for finishing the Kimura when your opponent is stalling by clasping their hands? A: Maintain the Kimura grip and positional pressure to accumulate advantages while systematically working to break the clasp. Use your free hand or stepover techniques to separate their hands—insert your knee between their clasped hands or peel their top hand with your free hand. If the grip persists, transition the threat by walking to north-south or threatening the back take, which forces them to address new threats and often releases the clasp reflexively.
Q9: Your opponent rolls toward the Kimura side during your finish attempt from top position—how do you capitalize on this movement? A: Follow their roll by maintaining the Kimura grip absolutely and using their rotational momentum to transition to back control. As they roll, swing your top leg over to establish hooks while keeping the figure-four intact throughout the transition. From the new back control position, you have a choice: finish the Kimura from behind, or release one hand to secure a seatbelt grip for traditional back attacks like the rear naked choke.
Q10: What distinguishes a high-percentage Kimura finish from a low-percentage attempt in terms of body positioning? A: A high-percentage finish features the attacker’s body perpendicular to the opponent with feet walked toward the head, chest heavy on the opponent’s torso, the Kimura grip deep near the elbow, and the finishing arc driving the hand behind and below the opponent’s back. A low-percentage attempt typically shows the attacker squared up rather than angled, weight resting on their knees rather than driving through the opponent’s chest, and grip positioned near the wrist providing insufficient leverage.
