SAFETY: Rear Triangle Choke from Rear Triangle targets the Neck. Risk: Loss of consciousness from bilateral carotid compression. Release immediately upon tap.
The rear triangle choke from the rear triangle position is one of the highest-percentage finishes available from back control. Once the triangle configuration is locked—with one leg threaded under the opponent’s armpit and across the back of the neck while the other leg secures the figure-four—the attacker controls both the head and one trapped arm. The choking mechanism compresses the carotid arteries bilaterally: the shin blade presses one side while the opponent’s own trapped shoulder drives into the other. This dual compression creates a blood choke that can produce unconsciousness in four to six seconds once fully engaged.
What distinguishes the rear triangle finish from other back attacks is that the legs perform the primary choking work, leaving both hands free for secondary control and adjustment. The attacker can use their hands to break defensive grips, control the free arm, or adjust hip angle to optimize squeeze mechanics. The finish requires precise hip positioning—angling toward the trapped arm side to maximize the cutting angle across the neck. Combined with knee compression and controlled hip extension, this creates a submission that is mechanically efficient and extremely difficult to defend once the triangle is properly locked.
Strategically, this finish sits at the apex of a submission chain from rear triangle position. Opponents who defend the choke expose the trapped arm to armbars; those who address the arm expose the neck to tighter compression. This dilemma-based attack structure makes the rear triangle choke a high-percentage competition finish that rewards patience and systematic tightening over explosive force.

Safety Guide
Injury Risks:
| Injury | Severity | Recovery Time |
|---|---|---|
| Loss of consciousness from bilateral carotid compression | CRITICAL | Seconds to minutes if released promptly; permanent neurological damage possible if held beyond 10-15 seconds after unconsciousness |
| Tracheal bruising or cartilage damage from improper shin placement across the windpipe | High | 1-4 weeks for bruising; 6-12 weeks for cartilage injury |
| Cervical spine strain from excessive posture breaking or neck cranking during finish | Medium | 1-3 weeks for mild strain; 4-8 weeks for moderate injury |
Application Speed: SLOW and progressive. Blood chokes can cause unconsciousness in 4-6 seconds once fully locked. Apply squeeze gradually and monitor opponent continuously. Never jerk, spike, or explosively tighten the triangle.
Tap Signals:
- Verbal tap (saying ‘tap’ or any distress signal)
- Physical hand tap on partner, your body, or the mat
- Physical foot tap with free leg on mat or partner
- Any unusual vocalization, gurgling, or distress sounds
- Body going limp or cessation of all defensive movement (unconsciousness indicator—release immediately)
Release Protocol:
- Release immediately upon any tap signal without hesitation
- If opponent goes limp or stops responding, release immediately and alert instructor
- If in doubt whether a tap occurred, release—position can always be re-established
- After release, check opponent’s consciousness and responsiveness before continuing
- Place unconscious training partner in recovery position and call for medical assistance
Training Restrictions:
- Never apply full squeeze pressure on training partners below blue belt or with less than one year of consistent training
- Always use controlled, progressive application during drilling—save competitive-speed finishing for supervised sparring only
- Do not hold the choke after the tap to demonstrate control; release is immediate and unconditional
- Practitioners with neck injuries, cardiovascular conditions, or blood pressure disorders should consult a physician before training this technique

Playing as Attacker
Key Principles
-
Angle hips toward the trapped arm side to create optimal cutting angle across the carotid arteries
-
Squeeze knees together before extending hips to eliminate all dead space in the triangle structure
-
Use hands to control the free arm and prevent defensive grip establishment throughout the finish
-
Apply progressive pressure rather than explosive force to maintain control and monitor opponent response
-
Break opponent’s posture forward by pulling their head toward their chest using leg compression
-
Maintain chest-to-back connection to prevent opponent rotation during the finishing sequence
Execution Steps
-
Verify triangle lock integrity: Confirm the figure-four is properly locked with the ankle seated deep in the knee crook. The choking…
-
Control the free arm: Use both hands to establish control over the opponent’s free arm by gripping the wrist, establishing…
-
Angle hips toward trapped arm: Rotate your hips and torso so they face the trapped arm side at approximately 45 degrees. This hip a…
-
Squeeze knees together: Before extending your hips, actively squeeze your knees together to eliminate all remaining space wi…
-
Break posture forward: Use your leg pressure to curl the opponent’s head forward toward their own chest. Pull with your ham…
-
Extend hips to finish: With knees compressed and posture broken, extend your hips away from the opponent in a controlled, p…
-
Monitor and micro-adjust: If the initial squeeze does not produce a tap, maintain pressure and make micro-adjustments. Walk yo…
Common Mistakes
-
Positioning the shin across the front of the throat instead of behind the neck
- Consequence: Creates a windpipe choke instead of a blood choke, which is less effective, slower to finish, and causes unnecessary tracheal trauma to training partners
- Correction: Thread the choking leg deep under the armpit until the shin emerges behind the opponent’s neck. The calf should contact the back and side of the neck, not the front of the throat
-
Extending hips before squeezing knees together to seal the triangle
- Consequence: Creates gaps in the triangle that allow the opponent to relieve pressure or extract their trapped arm during the finishing attempt
- Correction: Always compress knees together first to eliminate space, then extend hips as the second phase of the finishing sequence
-
Releasing chest-to-back contact while focusing entirely on the leg squeeze
- Consequence: Allows the opponent to rotate freely, create distance, or change angles that compromise the triangle structure and finishing mechanics
- Correction: Maintain chest pressure against the opponent’s back throughout the entire finishing sequence. Upper body connection and lower body squeeze work as a unified system
Playing as Defender
Key Principles
-
Protect the chin immediately by tucking it tight to the chest and turning the face toward the non-choking leg side to reduce carotid exposure
-
Prioritize trapped arm extraction over all other defensive actions—the trapped arm is what makes the triangle function as a choke
-
Fight the knee squeeze by inserting your free hand between the attacker’s knees to create space in the triangle structure
-
Deny the attacker’s hip angle by turning your body away from the trapped arm side to reduce the cutting angle across the neck
-
Control the attacker’s choking leg ankle or knee with your free hand to prevent further tightening and create escape leverage
-
Manage breathing through controlled nasal inhalation to maximize oxygen under restricted airway conditions
-
Act with urgency but not panic—deliberate sequential escape movements succeed where frantic thrashing fails
Recognition Cues
-
Feeling a leg thread under your armpit from behind while in back control, with the shin crossing behind your neck rather than across the front
-
Sensing your arm become trapped between the opponent’s thigh and your own neck as the figure-four leg lock closes around you
-
Experiencing increasing bilateral pressure on both sides of your neck simultaneously, indicating carotid compression from the triangle structure
-
Noticing your posture being broken forward as the attacker’s legs curl your head toward your chest, restricting your ability to extend upward
-
Feeling the attacker’s hips angle toward your trapped arm side, creating a progressive tightening sensation around your neck
Escape Paths
-
Extract trapped arm from the triangle, then shrimp hips away and work to turtle position before recovering guard
-
Break the figure-four by peeling the locking ankle, then fight back to standard back defense positioning
-
Roll toward the non-choking leg side during the attacker’s hip extension to collapse the triangle and scramble to guard
