Triangle from Mount

SubmissionTop triangle chokeBelt: blue+Risk: moderateIBJJFADCCNo-GiSub-OnlyMMA

The triangle from mount is a top-position submission where you encircle the opponent's head and one arm with your legs, finishing with a strangle. It is a powerful option when the opponent defends mount by framing or pushing on your body, allowing you to trap their arm and transition to a high-percentage choke.

Submission
Prerequisites: Cross-face control · Isolating an arm · Posting for base · Hip mobility from mount

Steps

  1. 1
    Establish High Mount
    Slide your knees up into the opponent’s armpits, keeping your hips low and chest heavy to limit their elbow mobility and maintain control.
  2. 2
    Isolate the Nearside Arm
    Use a cross-face or underhook to force one of their arms across their centerline; simultaneously, post your opposite hand for base and use your knee to wedge under their triceps.
  3. 3
    Thread Your Leg Over the Head
    Shift your weight forward and post on your hands; swing your far leg (relative to the trapped arm) over their head, aiming to place your knee close to their ear while keeping your toes pointed for tightness.
  4. 4
    Lock the Triangle Position
    Bring your other leg around, crossing your ankles initially, then adjust so your ankle of the leg over their neck tucks behind the knee of your other leg, forming a tight triangle configuration.
  5. 5
    Angle Off for the Choke
    Grab your shin (not your foot) to keep the triangle tight; rotate your body slightly toward the trapped arm side, creating a perpendicular angle for maximum pressure.
  6. 6
    Squeeze and Finish
    Flex your hamstrings and pinch your knees together, pulling their head down with both hands or a lat grip; elevate your hips and maintain the angle until you achieve the tap.
  7. 7
    Adjust if Necessary
    If their posture breaks or their arm starts to slip, re-grip your shin and re-angle your body, ensuring their arm stays across their neck and your triangle remains tight.

Key details most people miss

  • Use your knee as a wedge under their triceps to prevent their arm from retracting before threading your leg.
  • Grabbing your shin (not your foot) when locking the triangle maintains structural integrity and prevents slipping.
  • Angling your body perpendicular to their torso greatly increases choke efficiency and prevents stacking.
  • Keep your hips low and heavy during the initial setup to prevent explosive bridging escapes.

Common mistakes

  • Failing to isolate the arm allows the opponent to defend by tucking their elbow, making the triangle impossible.
  • Not angling off results in a loose triangle, letting the opponent posture up or stack you.
  • Crossing your feet instead of locking the triangle knee-behind-ankle makes the choke weak and easy to escape.
  • Swinging the leg too slowly or without weight forward lets the opponent bridge and reverse you.
