Fulcrum Headlock Choke From Front Headlock Forearm-Fulcrum

Variety

フルクラムヘッドロックチョーク(Furukuramu Heddorokku Chōku)

Transliteration

Translation: Fulcrum Headlock Choke (katakana loanword)

Overview

The forearm-fulcrum headlock choke uses the flat or bony edge of the forearm as the fulcrum surface against the opponent's neck from a front headlock. ^[1] Unlike the elbow-point variant, the forearm fulcrum distributes pressure across a wider area while still concentrating force through the radial bone edge. ^[1],[2] The attacker positions the forearm across the throat, then uses the opposing arm to press the opponent's head into the forearm, creating a wedge effect that compresses the carotid arteries bilaterally. ^[2] The forearm variant is considered more controllable than the elbow point, making it more suitable for training and competition contexts where measured application is desired. ^[2],[3]

Also known as

Forearm-Fulcrum Headlock ChokeWrestling^[1]Forearm Lever Front Choke^[2]

Used in

BJJ Judo Submission Grappling MMA Sambo

History & Origin

Forearm fulcrum chokes are documented across multiple grappling traditions, from Japanese jujutsu to European catch wrestling. ^[1] The front headlock application was systematised in modern submission grappling as a finishing option when guillotine and D'Arce entries were not available. ^[2],[3]

Effectiveness

The forearm-fulcrum provides wider contact than the elbow, making it easier to position on the carotid. The radius bone creates rigid focal pressure when the forearm is rotated correctly. ^[1]

Lineage

Traditional catch wrestling forearm-pressure technique adapted for the BJJ front headlock position. The forearm rotation detail (bone-to-artery contact) comes from catch wrestling instruction. ^[1]

Competition Record

Used in catch wrestling competition and submission grappling. More common than the elbow-fulcrum variant due to easier positioning. ^[1]

Biomechanical Mechanism

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

Position & Entry

From sprawl (takedown defence) — After sprawling on a shot, secure the head-and-arm position from the front headlock

From snap-down — Snap opponent's head down with collar tie, drop to front headlock position, thread the choke

From guard (opponent postures low) — Opponent drops head, wrap the neck and thread to the choking configuration

Variants

Standard grip variation — primary hand configuration for maximum choking pressure

Gi variation — uses the lapel or collar as an anchor for additional friction and control

No-gi variation — adapted grip and positioning for submission grappling without the gi

Transition finish — applied during a positional change to catch the opponent off-guard

Training Notes

✓The forearm-fulcrum headlock choke uses the radius bone of the forearm as a bar pressed across the neck from front headlock — the bone creates a rigid choking surface against the carotid arteries (Danaher, Front Headlock System: Go Further Faster, 2019)

✓From front headlock: rotate the forearm so the radius bone (thumb-side) presses directly into the neck — the bone acts as a bar that compresses the artery

✓The forearm fulcrum distributes pressure more than the elbow but over a wider area: the radius bone contacts several centimetres of neck, potentially compressing both carotids simultaneously

✓The finish: squeeze the choking arm while the other arm controls the head — the forearm bone rolls into the neck as the arm tightens

✓The forearm-fulcrum is the more common fulcrum variation: the wider contact area makes it easier to position correctly — the elbow fulcrum requires more precision

✓From front headlock: the forearm fulcrum works as a direct attack or as a transition to the guillotine — the pressure forces the opponent to react, creating openings

✓The forearm rotation is the key detail: turning the wrist so the radius contacts the neck (rather than the flat of the inner forearm) creates bone-on-artery pressure

Common Mistakes

!Using the flat of the inner forearm — rotate so the radius bone contacts the neck; the soft inner forearm lacks the rigidity for focal pressure

!Not controlling the opponent's head — the head must be trapped and still for the forearm to maintain artery contact

!Pressing into the trachea — target the lateral neck; the forearm should be angled across the carotid groove

!Squeezing without forearm rotation — the rotation is what brings the bone to the surface; squeezing with a flat forearm creates general pressure, not focal compression

!Attempting from a loose front headlock — positional control is prerequisite; without a tight headlock, the opponent turns away

!Not adjusting if the first position doesn't work — slight movements of the forearm can find the artery; static holding may miss the target

!Using the forearm fulcrum exclusively — it should be part of a system; if the fulcrum is defended, transition to guillotine or anaconda

Related Techniques

Counter Techniques

Tuck Chin — protect the neck by lowering the chin to prevent the choke from sinking Two-on-One Grip Fight — use both hands to strip the choking grip before it locks Turn Into — rotate toward the choking arm to relieve carotid pressure Posture Up — straighten the spine and create distance to break the choking angle

Setup Chain

1Achieve Controlling Position — secure the position from which the choke is applied

2Isolate the Neck — clear defending hands and establish access to the throat

3Set the Grip — lock the choking configuration (arm, lapel, or leg placement)

4Apply Pressure — squeeze to compress the carotid arteries for the finish
