Triangle Armbar

Last updated: June 25, 2026

What is a triangle armbar?

A triangle armbar blends two of grappling’s oldest submissions into one finish. The attacker first locks a triangle, wrapping the legs in a figure-four around the opponent’s neck and one arm. From there, rather than squeezing for the strangle, they isolate the trapped arm and crank it straight, bending the elbow past its natural range until the opponent taps.

It comes down to the position. A locked triangle already traps the head and one arm, so that arm sits right there in the open, asking to be attacked. Defend the choke by posturing up, and you straighten the exact arm your opponent wants.

This pairing has real history behind it. The triangle was a known judo move long before it caught on in Brazilian jiu-jitsu, but early grapplers found it too easy to defend on its own. Linking the triangle to the armbar is what turned it into a genuine threat, according to BJJ Heroes. The UFC now logs triangle armbar as its own finish in official fight stats, distinct from a plain armbar or a triangle choke.

How a triangle armbar works

Picture a fighter flat on their back with their legs clamped high around the other fighter’s neck and one arm. That is the triangle. The shin presses across the neck on one side, the opponent’s own shoulder closes off the other, and a single arm runs across the attacker’s body.

When the trapped opponent tries to escape by posturing up or stacking forward, the choke loosens, but the captured arm straightens out. Now it is a target. The attacker grips the wrist, angles the hips to line up with the elbow, and extends. The joint hyperextends, and the tap follows.

On a broadcast, the tell is simple. The legs stay locked in the triangle shape, but the finish comes from wrenching the arm rather than strangling the neck. A triangle choke takes around 9.5 seconds on average to put someone to sleep once it is tight, per data cited on Wikipedia, so switching to the arm gives the attacker a faster, second way to end the fight when the choke stalls.

Triangle armbar vs. triangle choke vs. armbar

People mix these three up constantly, which is fair, because they share the same family. The difference is what gets attacked and how the fight ends.

Submission	What it targets	Finishing action	Why the opponent taps
Triangle choke	The neck, with one arm trapped	Legs squeeze the carotid arteries shut	Blood to the brain is cut off
Armbar	The elbow joint	Hips drive the straight arm past its range	The elbow is about to break
Triangle armbar	Neck first, then the trapped arm	Triangle legs isolate the arm, then hyperextend it	The elbow gives out

A triangle choke is a strangle. A standard armbar isolates the arm with no triangle involved. The triangle armbar borrows the leg control of the triangle and finishes like an armbar, which is why it gets its own name.

Common misconceptions

The biggest mix-up is between a triangle armbar and an arm triangle choke. They sound almost identical and mean completely different things. An arm triangle, also called kata-gatame, is a strangle that traps the neck against the opponent’s own shoulder using your arm, with no legs involved at all. A triangle armbar uses the legs to trap the head and arm, then attacks the elbow.

A second point of confusion is the phrase “armbar from triangle.” That describes the same move, just named from the other direction.

It also helps to know that a triangle armbar is often not a planned attack. Plenty of the time, it shows up as a reaction when an opponent defends the choke well and accidentally feeds the arm.

Triangle armbar in the UFC

You will mostly hear the term during a UFC broadcast, and there is a reason it stands out. The promotion counts triangle armbar as a separate submission category, and it almost never happens.

When Tatsuro Taira submitted Jesús Santos Aguilar at UFC Fight Night: Lewis vs. Spivac on February 4, 2023, the UFC billed it as just the 10th triangle armbar in company history. Taira got the finish at 4:20 of the opening round. Years earlier, at UFC 116 in 2010, Chris Lytle pulled off an inverted mounted triangle and straight armbar combination that Wikipedia still flags as a notable example of the hold. So when a commentator calls a triangle armbar, it usually means the fighter set the triangle and chose to break the arm.

Frequently Asked Questions

Is a triangle armbar the same as an armbar?

No. A standard armbar isolates the arm by itself. A triangle armbar first traps the head and arm in a triangle leg lock, then attacks the elbow from that position.

Is a triangle armbar a choke?

No. The triangle position can choke, but the triangle armbar finishes as a joint lock on the elbow, not a strangle.

Is the triangle armbar legal in MMA?

Yes. The triangle and the armbar are both legal submissions in the UFC and nearly every major promotion.

What is the difference between a triangle armbar and an arm triangle?

They are different holds. An arm triangle, or kata-gatame, is a choke that pins the neck against the opponent’s own shoulder using your arm. A triangle armbar uses your legs and attacks the elbow.
