Arm Triangle

The head-and-arm choke

The arm triangle is a blood-choke submission applied from a dominant top position. The attacker traps the opponent's arm against their own neck, then squeezes the head-and-arm sandwich until the carotid artery on the opposite side compresses against the opponent's own arm.

The technique is one of the highest-percentage submissions in modern MMA. Islam Makhachev's title-defense finishes regularly feature the arm triangle; Khabib's UFC 280 finish of Charles Oliveira was an arm triangle from mounted position.

Mechanics

From side control, attacking the right arm:

• Force the arm across the neck: push the opponent's right arm across their face, so it's positioned across their own neck.
• Lock the head-and-arm position: the attacker's right arm wraps over the opponent's head and under their right armpit, gripping the back of their own right shoulder.
• Sprawl out: the attacker slides their hips away from the opponent's body, creating space for the squeeze.
• Squeeze: bring the shoulders together while the attacker's chin tucks toward the opponent. The carotid compresses against the opponent's own shoulder.
• Finish: maintain squeeze pressure until the opponent taps or loses consciousness.

Setup positions

• Side control top: the most common entry.
• Mount: with the opponent's arm trapped against their face.
• Knee on belly: transitioning from knee-on-belly to the arm triangle.
• Half guard top: attacking the arm triangle from inside half guard.

Common errors

• Arm not deep enough across the neck: the opponent's arm needs to be fully across their own neck.
• Insufficient sprawl: the attacker needs to sprawl out to create the angle for the squeeze.
• Losing position before the choke locks: gives the opponent the chance to escape.
• Squeezing in the wrong direction: the squeeze direction matters for the compression to work.

Defense

• Connect the hands: lock both arms across the chest to prevent the trapped-arm position.
• Shrimp out: hip-escape to reset to a recoverable position.
• Posture defense: from the bottom, drive the trapped arm out before the lock sets.

Variations

• Side-control arm triangle: textbook version.
• Mounted arm triangle: applied from mount.
• Standing arm triangle: rare but possible from clinch range.
• Reverse arm triangle: D'Arce or anaconda-style variations.

Exemplified by

• Islam Makhachev: the title-defense arm-triangle finishes of Charles Oliveira (UFC 280), Drew Dober, and others.
• Khabib Nurmagomedov: the arm-triangle threats integrated with his top-position game.
• Anderson Silva: arm-triangle finishes across his middleweight career, including the Travis Lutter finish.
• Demian Maia: high-frequency arm-triangle finishes in his welterweight title-contender career.

Drills

• Position drill: from cooperative side control, drill the arm-triangle entry and finish.
• Mounted arm-triangle drill: from full mount, drill the arm-triangle setup.
• Defense drill: partner attacks the arm triangle; you practice connecting hands and posturing.
• Live ground sparring from top position: rounds where the arm triangle is the primary submission target.
