SAFETY: Rear Naked Choke from Harness targets the Carotid arteries and jugular veins. Risk: Loss of consciousness from bilateral carotid compression. Release immediately upon tap.
Executing the Rear Naked Choke from Harness requires patience and systematic grip advancement. The primary challenge is transitioning from the controlling seatbelt configuration to the figure-four choking position while the opponent actively defends with two-on-one grip control, chin tucking, and shoulder shrugging. Success depends on creating dilemmas that force the opponent to choose between defending the choke and maintaining positional integrity, then capitalizing on the resulting openings with decisive arm placement and proper squeeze mechanics. The harness provides the ideal launching platform because the choking arm is already positioned over the shoulder, requiring only forward advancement rather than a full arm insertion from scratch.

Key Attacking Principles
What are the key principles for executing Rear Naked Choke from Harness?
- Maintain chest-to-back connection throughout the entire choke transition to prevent the opponent from creating the space needed to turn or escape
- Advance the choking arm in small increments using elbow walking rather than attempting one large movement that the opponent can anticipate and block
- Use the underhook arm to control the opponent’s posture and prevent them from turning into you while the choking arm advances toward the neck
- Create grip-breaking dilemmas by threatening the arm advancement from multiple angles so the opponent cannot establish a static two-on-one defense
- Apply the squeeze through chest expansion and structural mechanics rather than relying on arm strength alone, which fatigues rapidly
- Keep hooks active and engaged to prevent the opponent from using hip escapes or turns as an alternative to hand-fighting the choking arm
Prerequisites
What do you need before attempting Rear Naked Choke from Harness?
- Harness grip fully established with one arm over the opponent’s shoulder (choking arm) and one arm under the opposite armpit, hands connected at the chest or sternum
- At least one hook inserted with the instep controlling the opponent’s inner thigh to prevent hip rotation and turning escapes
- Chest-to-back connection maintained with forward pressure distributed through the core, not solely through grip tension
- Head positioned safely to the side of the opponent’s head, typically on the choking arm side, to avoid backward head pressure and maintain structural alignment
- Opponent’s defensive posture assessed to identify whether they are protecting the neck with hands high or fighting hooks with hands low
Execution Steps
How do you execute Rear Naked Choke from Harness step by step?
- Confirm harness control and assess defensive posture: Before initiating the choke transition, verify that your seatbelt grip is tight with hands clasped high on the chest, at least one hook is secure, and your chest is pressed firmly against the opponent’s back. Assess whether the opponent’s hands are defending the neck or fighting your hooks, as this determines your initial advancement strategy. (Timing: 2-3 seconds assessment)
- Begin choking arm advancement with elbow walking: Start sliding the choking arm (the over-the-shoulder arm) from its position on the chest toward the opponent’s neck. Use small elbow-walking movements rather than one large pull. Release the grip connection briefly if needed, using the underhook arm to maintain control while the choking hand advances one to two inches at a time toward the jawline. (Timing: 3-8 seconds depending on resistance)
- Defeat the two-on-one grip defense: The opponent will likely grab your choking wrist with both hands. Counter by using your free hand to peel their top grip finger by finger, or swim your underhook hand over their defending arm to strip grips. Alternatively, use a push-pull motion where you push their defending elbow away with your free hand while simultaneously advancing the choking arm forward. Create a dilemma by threatening an armbar if they commit both hands too aggressively. (Timing: 5-15 seconds of hand fighting)
- Clear the chin barrier and slide the forearm under: Once grip control is established on the wrist defense, work the blade of your wrist along the jawline and under the chin. If the opponent tucks their chin hard, use your free hand to cup their forehead and tilt the head back slightly, or walk your choking arm across the face from ear to chin. The forearm should slide under the chin with the blade of the wrist centered on the throat, angled so the radius bone contacts the carotid arteries rather than the trachea. (Timing: 2-5 seconds for chin clearing)
- Lock the figure-four choking configuration: Once the choking forearm is under the chin, immediately grab your own bicep with the choking hand while your free hand cups behind the opponent’s head or grabs the crown. Pull your elbows together to close any remaining space. The crook of the choking elbow should be centered under the chin with the forearm and bicep creating bilateral pressure on both carotid arteries simultaneously. Ensure no pressure is on the trachea. (Timing: 1-2 seconds to lock)
- Apply the squeeze with proper body mechanics: Generate choking pressure by expanding your chest forward while pulling your elbows back and together. Think of squeezing your shoulder blades together behind the opponent’s head. Use your hooks to prevent any last-second escape by pulling your heels into their thighs. The squeeze should be steady and progressive, not a sudden jerk. Your chest expansion creates the primary compression force while your arms maintain the structural frame around the neck. (Timing: 3-5 seconds progressive squeeze in training)
- Adjust angle and maintain pressure until tap: If the initial squeeze does not produce a tap, micro-adjust by angling your body slightly to one side to increase unilateral carotid pressure. Pull the opponent’s body tighter against yours by engaging your hooks and arching your back slightly. Monitor for tap signals constantly. If the opponent’s defense creates space in the figure-four, re-tighten by pulling elbows closer together and re-expanding the chest. Release immediately upon any tap signal. (Timing: Continuous until tap or release)

Opponent Defenses
How might your opponent defend against Rear Naked Choke from Harness?
- Two-on-one grip control on the choking arm wrist, preventing advancement toward the neck (Effectiveness: High) - Your Response: Use your free hand to strip their top grip finger by finger while maintaining forward pressure on the choking arm. Alternatively, threaten an armbar on the defending arm to force them to release, or swim your underhook hand over their defending arm to break the grip structure. → Leads to Harness
- Deep chin tuck with shoulder elevation creating a barrier to forearm entry under the chin (Effectiveness: Medium) - Your Response: Use your free hand to cup the forehead and tilt the head back, or walk the choking arm across the face from ear to chin. If chin remains tucked, apply the choke over the chin - the jaw acts as a lever that creates significant discomfort and often forces the opponent to lift their chin. → Leads to Harness
- Turning the body toward the choking arm side and hip escaping to recover guard (Effectiveness: Medium) - Your Response: Follow the turn by adjusting your hooks and maintaining chest contact. Use the underhook arm to block their hip rotation and pull them back to center. If they commit fully to the turn, transition to a mounted triangle or crucifix position rather than fighting the rotation. → Leads to Closed Guard
- Stripping hooks while defending the neck to create escape mobility (Effectiveness: Low) - Your Response: If opponent removes a hand from choking arm defense to fight hooks, immediately advance the choking arm toward the neck. The hook removal creates a momentary opening where only one hand defends the choke. Capitalize on this by accelerating the arm insertion before they can return both hands to the defense. → Leads to Harness
