Visual Execution Sequence

Detailed step-by-step description for clear movement sequence visualization:

From a dominant position such as mount or side control, you begin by identifying and isolating one of the opponent’s defensive arms, deliberately pushing it across their own neck to establish the foundational structure of the choke, with their own limb becoming an integral part of the choking mechanism. You position your head on the same side as the trapped arm to prevent them from pulling it back to safety, maintaining heavy pressure on their chest with your body weight while you carefully thread your choking arm around both their head and their trapped arm together. Your hands connect in either a figure-four grip (one wrist grasping the opposite bicep) or a gable grip (palms together or fingers interlocked), locking the choke structure in place and creating a sealed frame around their neck and shoulder. You methodically position your chest directly over their shoulder on the choking side, eliminating all defensive space between your torso and their upper body, while simultaneously aligning your shoulder to press against the side of their neck where the carotid artery runs. As you sense their defensive efforts weakening under the mounting pressure, you slide your entire body to the side opposite their trapped arm, transitioning from a more perpendicular position to a parallel alignment that dramatically increases the angle and compression force on their neck. You expand your chest outward while simultaneously squeezing your arms together and driving your shoulder into their carotid artery, creating a tightening vice that progressively restricts blood flow to their brain until the mounting pressure forces them to tap repeatedly on your body or the mat in clear submission, at which point you immediately release all pressure and allow them to recover safely.

Template: “From mount or side control, isolate opponent’s arm and push against their neck, position head same side. Thread arm around their head and trapped arm, connect hands in figure-four or gable grip. Position chest over shoulder eliminating space, align shoulder to carotid artery. Slide body to opposite side increasing angle, expand chest and squeeze arms while driving shoulder into carotid. Apply progressive pressure until tap, release immediately for safe recovery.”

Execution Steps

SAFETY REMINDER: Apply pressure SLOWLY over 3-5 seconds. Watch for tap signals continuously. Blood chokes cause unconsciousness - monitor partner’s consciousness and color.

Step-by-Step Execution

Step 1: Position and Arm Isolation (Setup Phase)

From mount or side control, isolate one of the opponent’s arms by pushing it against their neck, setting up the choking configuration.

Their arm becomes part of the choke structure
Push their arm across their own neck
Maintain dominant top position throughout
Safety check: Ensure partner can tap with free hand

Step 2: Head Positioning (Alignment Phase)

Position your head on the same side as the trapped arm, creating tight connection and control.

Your head goes next to their trapped arm
This prevents them from pulling the arm back
Keep your weight heavy on their chest
Partner check: They should be able to breathe normally at this stage

Step 3: Arm Threading and Grip Connection (Lock Phase)

Thread your arm around their head and trapped arm, connecting your hands in a figure-four or gable grip.

Your arm encircles both their head and arm
Figure-four: One wrist grips opposite bicep
Gable: Palms together or fingers interlocked
Speed: Smooth threading motion, not rushed
Watch for: Hand fighting or bridging attempts

Step 4: Chest-to-Shoulder Connection (Compression Phase)

Position your chest directly over their shoulder, eliminating all space between your body and theirs.

Your chest weight compresses down onto their shoulder
No daylight between your chest and their shoulder
This connection is critical for pressure
Monitor: Their facial expression and breathing pattern

Step 5: Shoulder Alignment to Carotid (Execution Phase - APPLY SLOWLY)

Align your shoulder to apply pressure directly against their carotid artery while expanding your chest over 3-5 seconds.

Your shoulder should be on the “choking” side of their neck
Expand chest outward to increase pressure
The opponent’s own shoulder helps compress their carotid
Critical: WATCH FOR TAP - loss of consciousness occurs quickly
If partner’s face turns red/purple, they’re seconds from passing out

Step 6: Angle Adjustment and Finish (Completion Phase)

Slide to the side opposite the trapped arm, increasing the angle and pressure while squeezing with your arms and expanding your chest.

Slide your body perpendicular to theirs
This angle maximizes carotid compression
Squeeze arms while expanding chest
FEEL FOR TAP: Hand tapping, verbal “tap”, body going limp
RELEASE IMMEDIATELY:
- Release your grip instantly
- Remove all chest pressure
- Roll off to give them space
- Check consciousness: “You okay? Can you hear me?”
- If they passed out: Elevate legs, monitor breathing, check for alertness
Post-submission: Verify normal color, alertness, no confusion
Watch for: Dizziness, disorientation, delayed response (signs of brief unconsciousness)

Total Execution Time in Training: 3-5 seconds from chest compression to tap. In drilling, stop at 60-70% pressure to safely develop technique without risking unconsciousness.

Defensive Considerations

Common Threats During Attempt

Primary risks while attempting this submission:

Position Loss: Opponent bridges or rolls → Guard Recovery (Threat Level: Medium)
Counter Submission: Opponent attacks with leg locks if hips exposed → Leg Lock Control (Threat Level: Low)
Escape: Opponent extracts arm and creates space → Neutral Position (Threat Level: Medium)
Stalemate: Opponent tucks chin and stalls → Defensive Position (Threat Level: Low)

Format: [[Threat Type]] → [[standing position]] (Threat Level: X)

Defensive Strategies

Methods to mitigate threats:

Arm Control: Maintain tight isolation of opponent’s arm to prevent extraction
Pressure Maintenance: Keep chest-to-shoulder connection to limit space
Hip Awareness: Position hips to avoid leg lock entries
Angle Adjustment: Slide to side early to prevent bridging escapes
Grip Security: Use strong grip to resist hand fighting attempts

Educational Content

Expert Insights

Commentary as if from recognized authorities:

John Danaher: “The arm triangle is a fundamental submission that succeeds through precise shoulder alignment rather than brute strength. The key is understanding that the pressure must be applied to the carotid artery using the opponent’s own shoulder as a lever. This technique teaches critical principles of mechanical advantage that apply to all chokes.”
Gordon Ryan: “In competition, the arm triangle is a high-percentage finish from mount because it exploits defensive framing. I use strategic weight distribution to maintain shoulder connection to their jaw, preventing escapes. The submission demonstrates how to turn an opponent’s defense into a vulnerability.”
Eddie Bravo: “The arm triangle integrates well with unorthodox positions like the Truck, creating dual threats of choke and positional advancement. It often forces opponents to expose other submissions when defended. This technique shows how traditional chokes can be adapted for modern grappling dynamics.”

Each insight should focus on one key technical or strategic element.

Common Errors

For knowledge test generation:

Error: Squeezing with arms only instead of using shoulder pressure
Why It Fails: Ineffective pressure leads to fatigue without submission
Correction: Focus on aligning shoulder to carotid artery and expanding chest
Recognition: Opponent does not show signs of distress despite grip
Error: Poor alignment of shoulder pressure
Why It Fails: Insufficient compression on carotid artery for blood choke
Correction: Ensure shoulder is directly over opponent’s shoulder and neck
Recognition: Choke feels weak despite tight grip
Error: Rushing the finish without eliminating space
Why It Fails: Allows opponent to create defensive space and escape
Correction: Maintain chest-to-shoulder connection before sliding to side
Recognition: Opponent easily frames or extracts arm during attempt

Timing Considerations

When to attempt this submission:

Optimal Conditions: When opponent’s arm is framed or exposed during escape attempt
Avoid When: Opponent maintains strong defensive posture with chin tucked
Setup Sequences: After failed mount escapes or other submission threats
Follow-up Windows: Must complete within 5-10 seconds to prevent counter or fatigue
