SAFETY: Rear Naked Choke from Body Triangle targets the Carotid arteries and jugular veins. Risk: Loss of consciousness from blood choke. Release immediately upon tap.
The Rear Naked Choke from Body Triangle combines the highest-percentage submission in grappling with the most secure form of back control. The body triangle’s figure-four leg lock around the opponent’s torso creates constant breathing restriction and prevents standard back escape sequences, giving the attacker extended time to systematically work through the choking sequence without concern for positional loss.
Unlike the standard RNC from hooks where the attacker must constantly manage leg positioning, the body triangle frees both arms entirely for neck attack. The locked legs cannot be cleared through hip escaping or hook removal, meaning the defender must first solve the triangle problem before addressing the choke — a two-layered defensive challenge that dramatically reduces escape success rates. The breathing restriction from the triangle also forces the defender to work urgently, often leading to defensive errors that expose the neck.
The finishing mechanics remain identical to the standard RNC — the choking arm slides under the chin with the bicep and forearm compressing both carotid arteries — but the body triangle provides a force multiplier. The squeeze from the legs restricts the defender’s ability to expand their chest and generate the power needed for effective hand fighting. Competition data consistently shows that RNC attempts from body triangle convert at significantly higher rates than from standard hooks, making this one of the most feared finishing combinations in modern grappling.

Safety Guide
Injury Risks:
| Injury | Severity | Recovery Time |
|---|---|---|
| Loss of consciousness from blood choke | High | Immediate to 30 seconds with proper release |
| Trachea damage from improper forearm placement | CRITICAL | 2-6 weeks, potential permanent damage |
| Neck strain or muscle damage | Medium | 3-7 days |
| Carotid artery injury from excessive force | CRITICAL | Immediate medical attention required |
Application Speed: SLOW and progressive - 3-5 seconds minimum in training. Never snap or jerk the choke. Partner should have full awareness of pressure building.
Tap Signals:
- Verbal tap (say ‘tap’ or make any verbal sound)
- Physical hand tap on opponent’s body or mat
- Physical foot tap on mat
- Going limp or loss of consciousness
- Any distress signal or unusual sound
Release Protocol:
- Immediately release choking arm upon tap signal
- Remove hooks and body triangle lock
- Gently guide partner to side-lying recovery position
- Monitor consciousness and breathing for 30 seconds
- If partner was unconscious, keep them lying down until fully alert
- Never allow unconscious partner to stand immediately
Training Restrictions:
- Never use competition speed or intensity in drilling
- Never apply the choke to the trachea or windpipe
- Always ensure partner has clear tap access with both hands
- Stop immediately if partner makes any distress sound
- Never hold a choke past the tap for any reason
- Beginners must practice with extremely slow progression only

Playing as Attacker
Key Principles
-
Use the positional security of the body triangle to methodically strip defensive grips rather than rushing the choke — patience converts to finishes
-
Slide the choking forearm under the chin at an angle from the side rather than forcing it straight through the center defense
-
Time your leg squeeze pulses with arm advancement to overwhelm the defender’s ability to address both threats simultaneously
-
Press your head against the side of opponent’s head to prevent chin tucking and control their head angle throughout the sequence
-
Ensure the choking arm is deep enough that the blade of your forearm crosses both carotid arteries before committing to the finishing squeeze
-
Maintain constant chest-to-back connection throughout the hand fighting sequence to prevent any space creation that enables escape

Common Mistakes
-
Rushing the choke before establishing proper arm position through hand fighting
- Consequence: Choking arm gets trapped in defensive grips, wasting energy, telegraphing the attack, and allowing opponent to establish strong two-on-one defense
- Correction: Use patient hand fighting and systematic grip stripping from the seatbelt before committing the choking arm — let the body triangle pressure create the openings
-
Placing forearm directly across the trachea instead of angling across the carotid arteries
- Consequence: Creates a painful air choke that is slow to finish, easier to defend, and risks serious tracheal damage including potential permanent injury
- Correction: Angle the forearm blade across both sides of the neck with the crook of the elbow centered directly under the chin — the forearm should contact carotid arteries, not the windpipe
-
Failing to control opponent’s head before attempting to finish the choke
- Consequence: Opponent tucks chin creating a barrier that prevents full arterial compression, stalling the choke and allowing them to reset defensive grips
- Correction: Use the non-choking hand behind the head to push it forward into the choke before squeezing — the head trap eliminates the chin tuck defense
Playing as Defender
Key Principles
-
Chin protection is the first and constant priority — keep chin tucked with at least one hand defending the neck at all times throughout the position
-
Fight the setup rather than the locked choke — preventing the choking arm from threading under the chin is far more achievable than escaping a fully locked RNC
-
Manage breathing under compression by taking controlled chest breaths rather than fighting for full diaphragmatic expansion that the triangle prevents
-
Never remove both hands from neck defense simultaneously — address the body triangle with one hand while maintaining neck protection with the other
-
Address threats in priority order: protect neck first, manage breathing second, work on triangle clearing third
-
Maintain mental composure under physical stress — accept the breathing discomfort and work methodically rather than panicking into energy-wasting scrambles
Recognition Cues
-
Opponent’s forearm begins sliding along your jawline or collar area, indicating the choking arm is advancing toward your neck
-
Increased body triangle squeeze pressure signals the attacker is about to commit to a choke attempt, using leg pressure to distract from arm advancement
-
Non-choking hand frames against your forehead or jaw attempting to tilt your head and break your chin tuck defense
-
One of your defensive grips is stripped from the collar area while opponent maintains seatbelt or upper body control
-
Head pressure from behind — opponent presses their head firmly against yours to control your head angle and prevent chin defense
Escape Paths
-
Clear the body triangle figure-four lock by attacking the ankle behind the knee, then turn into opponent to recover half guard or closed guard
-
Strip the choking grips, create space by bridging and turning, and stand up in base to break the position entirely
-
Stall the choke with two-on-one wrist control while systematically working the triangle clear with your free hand and hip movement
