The rear triangle applies the triangle choke from back control by locking the legs in a figure-four around the opponent's neck and one arm from behind. [1] The attacker, established on the opponent's back, threads one leg over the opponent's shoulder and under the chin, then hooks the foot behind the opposite knee to lock the triangle configuration. [1],[2] The rear triangle combines back control dominance with the powerful leg-based strangulation mechanics of the triangle choke, creating a nearly inescapable position. [2] This variant is particularly effective as an alternative to the rear naked choke when the opponent is defending the arms but leaving the neck exposed to leg attacks. [2],[3]
История и происхождение
The rear triangle was popularised in modern competition BJJ during the 2010s, with athletes like Ryan Hall demonstrating its effectiveness as a back attack alternative. [1] The technique represented an evolution in back attack strategy, expanding beyond arm-based chokes to include leg-based strangulation from the back. [2],[3]

Биомеханический механизм
Primary Action — Bilateral compression of the carotid arteries — restricts blood flow to the brain, causing unconsciousness within seconds
Joints Involved — Cervical spine (lateral flexion), glenohumeral joint of the trapped arm (if arm-in), nuchal region
Force Vector — Lateral squeeze creates inward pressure on both sides of the neck simultaneously
Choking Mechanism — Vascular strangle — occludes carotid arteries and jugular veins, distinct from airway (tracheal) chokes
Позиция и вход
From back control with seatbelt — Establish hooks or body triangle, slide choking arm under the chin, connect hands and squeeze
From turtle top (back take) — Break down the turtle, insert hooks, secure seatbelt grip, slide to back control and apply the choke
From standing back clinch — Secure rear body lock, drag opponent to the mat while inserting hooks, transition to choking position
Варианты
Short choke (palm-to-palm grip) — compact grip for tight spaces when the chin is partially tucked
Gable grip RNC — interlocked fingers behind the head for maximum squeeze pressure
Body triangle RNC — adds body triangle control for stronger hip management during the choke
One-arm RNC — single arm under the chin when the second arm cannot reach behind the head

✓The rear triangle (ushiro sankaku) locks the triangle choke configuration from behind the opponent — combining back control with the triangular strangling mechanism for one of the most inescapable submission positions (Danaher, Back Attacks: Enter the System, 2018)
✓The rear triangle is structurally identical to the front triangle but applied from behind: one leg crosses the front of the neck, the other locks the figure-four, and the opponent's arm provides the third side
✓The positional advantage is significant: from behind, the opponent cannot see the setup, cannot push the legs away easily, and cannot posture to create space
✓Entry: from back control, swim one leg from a hook position up and over the shoulder — the leg crosses the front of the neck diagonally
✓The trapped arm is typically the arm on the side where the leg crosses: this arm's shoulder gets compressed into the carotid as the legs squeeze
✓The rear triangle is a checkmate position: once locked with the figure-four behind the opponent, the escape options are extremely limited — the attacker has time to adjust and tighten
✓Gordon Ryan has demonstrated the rear triangle as a systematic back-attack option: when the RNC is defended, the triangle provides an alternative finishing mechanism
Типичные ошибки
!Attempting without first establishing stable back control — the leg-over-shoulder transition requires positional security; rushed attempts from loose back positions fail
!Not including an arm in the triangle — both arms outside the legs creates a headscissors; one arm must be inside for the triangular mechanism
!Locking the triangle with the wrong leg on top — the leg crossing the neck should create the long side of the triangle; the locking leg hooks behind its knee
!Not adjusting if the opponent begins to escape — the rear triangle has multiple finishing angles; if the initial angle is defended, rotate or shift rather than releasing
!Squeezing before the lock is complete — ensure the figure-four is fully connected before applying compression; premature squeezing alerts the opponent to defend
!Ignoring the opponent's bottom-side arm — the free arm can push against the locking leg; control it with your hands or trap it under your body
!Over-extending the legs during the lock — keep the hips close to the opponent; extending the legs creates space that weakens the triangle

Часто задаваемые вопросы
What's the correct angle for the rear triangle choke?
According to Stephan Kesting, the triangle must be positioned over the side of your opponent's neck, not over the back of their neck and shoulder. The angle is wrong if there's space between your knee and their neck—you need to scoot back far enough so your calf caps off the carotid arteries.
How do I finish the rear triangle once it's locked in?
Stephan Kesting emphasizes closing the triangle while ensuring your Achilles tendon insertion cuts off the artery, positioning your hip to internally rotate your opponent's shoulder into their neck, and using your thigh to break their posture—all while maintaining the postural control you've established.
Should I try to make lots of adjustments while setting up the rear triangle?
No—Stephan Kesting advises against unnecessary movements once you have control. Once you've established good positioning and posture break, minimize your adjustments and focus on closing and finishing the technique rather than constantly repositioning.
