SAFETY: Kimura from Side Control targets the Shoulder joint (rotation and elevation). Risk: Shoulder dislocation (anterior or posterior). Release immediately upon tap.
The Kimura from Side Control is one of the most fundamental and high-percentage shoulder locks in Brazilian Jiu-Jitsu, offering exceptional control and finishing potential from a dominant top position. This submission targets the shoulder joint through figure-four grip mechanics, creating rotational and elevational stress that forces the tap. From side control, the attacker has superior positioning, weight distribution, and multiple angles to establish the lock while the opponent’s mobility is severely restricted. The technique’s versatility allows for seamless transitions to other submissions, back takes, or positional advancements if the opponent defends. The Kimura grip itself becomes a powerful control mechanism, enabling the top player to manipulate the opponent’s posture, break their defensive frames, and create submission opportunities even when the finish isn’t immediately available. This makes it an essential tool for maintaining offensive pressure from side control while constantly threatening the finish.
From Position: Side Control (Top)
Key Attacking Principles
- Establish dominant side control with chest pressure before attacking the arm
- Secure the figure-four grip with proper wrist and forearm positioning for maximum leverage
- Control the opponent’s hip and prevent them from turning into you during the finish
- Maintain tight connection between your elbow and their body to prevent arm escape
- Apply pressure through elevation and rotation simultaneously, not jerking motions
- Use your body weight and positioning rather than pure arm strength
- Keep your base wide and stable throughout the submission sequence
Prerequisites
- Stable side control position with chest-to-chest pressure and no space
- Opponent’s near arm isolated and away from their body
- Your weight distributed to prevent opponent’s hip escape or reversal
- Dominant head position controlling opponent’s upper body movement
- Near-side knee tight to opponent’s hip to block turning
- Far-side base established to maintain balance during arm manipulation
- Opponent’s far arm controlled or neutralized to prevent framing
Execution Steps
- Establish Dominant Side Control: From side control, drive your chest weight into the opponent’s chest and shoulder area, eliminating all space. Your near-side arm should control their head or far shoulder while your hips stay heavy on their torso. Ensure your base is wide with your far leg posted out for stability. (Timing: 2-3 seconds to establish solid pressure)
- Isolate the Near Arm: Using your near-side hand, reach under the opponent’s near arm (the arm closest to you) and grip their wrist. Simultaneously use your head and shoulder pressure to pin their upper body and prevent them from pulling the arm back to their body. The goal is to create separation between their elbow and their ribs. (Timing: 1-2 seconds once pressure is established)
- Thread Your Arm for Figure-Four Grip: While maintaining wrist control with your near hand, thread your far arm over their arm and reach for your own wrist to establish the figure-four lock. Your forearm should be perpendicular to their forearm, creating the leverage structure. Keep your elbows tight together and close to their body to prevent them from straightening their arm. (Timing: 2-3 seconds to secure proper grip alignment)
- Control the Hip and Establish Base: Post your near-side knee tight against the opponent’s near hip to prevent them from turning into you. Your far leg should be posted wide and back for base. This hip control is critical - if they can turn toward you, they escape the submission. Maintain chest pressure throughout this adjustment. (Timing: 1-2 seconds)
- Elevate the Elbow: With the figure-four grip secured, begin lifting their elbow toward the ceiling while keeping it close to their body. The elevation should be smooth and controlled, not sudden. As you lift, maintain downward pressure with your chest to keep their shoulder pinned to the mat. This creates the initial stretch on the shoulder. (Timing: 2-3 seconds gradual elevation)
- Rotate the Arm Behind the Back: Once the elbow is elevated to approximately 90 degrees from their body, begin rotating their hand toward their back (like a hammerlock position). The rotation should be slow and progressive. The combination of elevation and rotation creates the shoulder lock. Stop immediately upon feeling tap or resistance. (Timing: 3-5 seconds progressive rotation)
- Finish with Walking Motion: If needed for the finish, walk your hips toward their head while maintaining the figure-four grip and continuing the rotation. This walking motion increases the angle and pressure on the shoulder joint. Continue applying slow, steady pressure until the tap, never jerking or spiking the submission. (Timing: 2-4 seconds if additional pressure needed)

| Counter | Closed Guard | 15% |
Opponent Defenses
- Opponent grabs their own belt or gi pants to prevent arm isolation (Effectiveness: High) - Your Response: Use your head and shoulder to drive their elbow away from their body while using your near hand to pry their grip open. Alternatively, transition to Americana or maintain control and wait for grip fatigue. → Leads to Side Control
- Opponent turns into you (toward your legs) to escape the rotation (Effectiveness: High) - Your Response: Block their hip with your near knee and maintain chest pressure to prevent the turn. If they succeed in turning, follow them to take the back or adjust to a rolling Kimura variation. → Leads to Closed Guard
- Opponent straightens their arm completely to break the figure-four structure (Effectiveness: Medium) - Your Response: Keep your elbows pinched together near their body to prevent full extension. If they straighten, transition to an armbar or use the Kimura grip to sweep them when they push. → Leads to Side Control
- Opponent bridges explosively to create space and escape their hips (Effectiveness: Medium) - Your Response: Maintain the Kimura grip and ride the bridge, then as they come down, immediately reestablish side control pressure. Use the grip to prevent them from turning away. → Leads to Side Control
- Opponent uses their free hand to push your head or create frames (Effectiveness: Low) - Your Response: Use your head position to swim under their framing arm or pin it with your body weight. Your dominant side control position should neutralize single-arm frames if your pressure is correct. → Leads to game-over
Test Your Knowledge
Q1: What is the minimum recommended application time for finishing the Kimura in training to ensure partner safety? [SAFETY-CRITICAL] A: 3-5 seconds minimum from position establishment to submission pressure. The shoulder joint is extremely vulnerable to injury from sudden or explosive movements. Progressive, slow application allows the training partner adequate time to recognize the submission, process the danger, and tap before injury occurs. Competition speed should never be used during training applications.
Q2: Why is controlling the opponent’s near hip with your knee essential before attempting the Kimura finish? A: Controlling the near hip prevents the opponent from turning into you, which is their primary and most effective escape from the submission. If they can rotate their body toward you, they reduce the rotational pressure on their shoulder and can escape the lock entirely. The knee post blocks this movement and maintains your superior angle for finishing. Without hip control, the submission is easily defended and you may lose position.
Q3: What are the two components of shoulder pressure that create the Kimura lock, and why must both be present? A: The two components are elevation (lifting the elbow away from the mat) and rotation (turning their hand toward their back behind their body). Elevation alone or rotation alone will not create sufficient pressure to finish the submission against a resisting opponent. The combination creates simultaneous stress on multiple planes of shoulder movement, targeting both rotational and elevational limits of the joint. Together they create an inescapable mechanical disadvantage for the defender.
Q4: What should you do immediately if your training partner cannot access their free hand to tap during the Kimura? [SAFETY-CRITICAL] A: Stop the submission immediately and release all pressure. If their free hand is trapped or inaccessible, they cannot signal tap through normal means, which creates a dangerous situation. You must be aware of their ability to tap throughout the entire submission sequence. Always ensure your partner has at least one hand free to tap, and watch for alternative tap signals like verbal taps or foot taps if hand access is compromised.
Q5: How should you adjust if the opponent successfully grabs their own belt or pants to defend their arm? A: Use head and shoulder pressure to drive their elbow away from their body while using your near hand to pry or break their defensive grip. If the grip is very strong, maintain control and wait for grip fatigue while applying chest pressure to prevent hip escape. Alternatively, you can transition to alternative submissions like the Americana which works well when they’re holding their own gi, or use the control time to advance position. Never force the grip break explosively as this can injure fingers or wrists.
Q6: What is the correct figure-four grip structure for maximum leverage in the Kimura? A: Your near hand grips the opponent’s wrist with your palm on their wrist bones. Your far arm threads over their arm and grips your own near wrist with four fingers, creating a bracket structure. Your forearm should be perpendicular to their forearm. Both elbows must stay tight together and close to their body - this is critical for maintaining leverage and preventing them from straightening their arm. The grip should feel like a solid frame with no gaps in the structure.
Q7: Why should you never elevate the opponent’s elbow beyond 90 degrees from their body during the Kimura finish? [SAFETY-CRITICAL] A: Elevating beyond 90 degrees creates extreme stress on the shoulder capsule and significantly increases the risk of shoulder dislocation, especially in opponents with limited flexibility or previous shoulder injuries. The submission is designed to finish through the combination of moderate elevation (around 90 degrees) and rotation. Excessive elevation can cause injury before the opponent feels sufficient pain to tap, as the shoulder can dislocate suddenly without warning. Safe application focuses on rotational pressure with controlled elevation.
Q8: Your opponent begins straightening their arm to break your figure-four structure - what immediate adjustment prevents the escape? A: Immediately pinch your elbows tighter together and drive them toward your opponent’s centerline, maintaining pressure on the bent arm. If their arm begins to straighten, use your chest weight to push their elbow toward the mat while maintaining wrist control. If the arm straightens past the point of recovery, transition immediately to an armbar by throwing your leg over their head - the straight arm is now perfectly positioned for this submission. Never waste energy fighting a fully straightened arm; instead, use it as a transition opportunity.
Q9: What anatomical structure does the Kimura specifically attack, and what creates the breaking point? A: The Kimura attacks the shoulder joint, specifically targeting the glenohumeral joint through extreme external rotation combined with elevation. The breaking point occurs when the rotator cuff muscles (subscapularis, supraspinatus, infraspinatus, teres minor) can no longer resist the rotational force being applied. The shoulder capsule and labrum are also stressed. The tap typically comes when the opponent feels the shoulder being forced past its natural range of motion in the rotational plane, creating sharp pain in the anterior shoulder.
Q10: At what point in the Kimura sequence has the opponent reached the point of no escape? A: The point of no escape occurs when you have secured the figure-four grip with tight elbows, established hip control with your knee blocking their turn, and begun the elevation phase with their elbow lifted off the mat. Once the elbow is elevated and your body weight is committed to the rotation, their defensive options become extremely limited. If they haven’t freed their arm before this point, their only remaining option is to tap. Recognizing this threshold in competition allows you to commit fully to the finish without fear of losing position.
Q11: Your opponent’s shoulder has limited flexibility and they tap earlier than expected - how do you adjust your finishing mechanics for different body types? [SAFETY-CRITICAL] A: Always communicate with training partners about flexibility limitations before drilling. For less flexible opponents, reduce your elevation angle significantly and rely more on rotation with the arm closer to the mat. Watch for early warning signs like grimacing or tension before verbal taps. Some practitioners may tap at 70-80 degrees of elevation that others can sustain without discomfort. In competition, recognize that inflexible opponents tap faster, so secure control and apply pressure progressively rather than explosively. Never assume everyone has the same range of motion.
Q12: How do you adjust your grip and positioning if you’re attempting the Kimura in no-gi versus gi competition? A: In no-gi, grip security becomes critical since there’s no gi material to anchor. Use a deeper figure-four grip where your grabbing hand wraps further around your own wrist for added security. Keep your body tighter to the opponent to prevent their arm from slipping due to sweat. Your chest pressure becomes even more important since you can’t use collar or sleeve grips to control position. Consider the wrist-ride variation where you grip their wrist more aggressively. In gi, you can use their sleeve to assist arm isolation and their belt or pants grip to add rotational pressure to the finish.
