From Prone Control

Species

伏せ制御から(Fuse Seigyo kara)

Traditional

Translation: from prone control

Overview

The figure-four wrist lock from prone control is applied by trapping the face-down opponent's wrist and locking a figure-four grip configuration to apply concentrated flexion force. ^[1],[2] The prone position prevents the opponent from rotating to relieve pressure, and the figure-four grip provides enough leverage to bend the wrist against muscular resistance. ^[1] The technique is commonly applied when the opponent extends an arm to post or attempt a turnover, exposing the wrist to the figure-four trap. ^[1],[2]

Also known as

Ground Figure-Four Wrist Lock^[1]Prone Figure-4 Lock^[2]

Used in

BJJ Judo Submission Grappling MMA Sambo

History & Origin

Figure-four wrist locks from prone control positions are widely used in law enforcement and military restraint training, where the face-down handcuffing position naturally exposes the wrist to manipulation. ^[1],[2] In sport grappling, the technique developed as top players found the figure-four provided enough mechanical advantage to finish wrist locks through the resistance of prone opponents. ^[1] The method bridges tactical restraint and sport submission. ^[1],[2]

Effectiveness

Prone control submissions attack a face-down opponent with chokes, cranks, and arm locks, exploiting a position where the bottom player has limited defensive options. ^[1]

Lineage

Prone control attacks were developed in catch wrestling (the 'chain wrestling' system) and adopted into modern BJJ. ^[1]

Competition Record

Prone position chokes and cranks are used in both MMA (ground-and-pound to submission sequences) and advanced BJJ competition. ^[1]

Biomechanical Mechanism

Primary Action — Forced flexion, extension, or rotation of the wrist beyond its normal range of motion

Joints Involved — Radiocarpal joint (wrist), intercarpal joints, distal radioulnar joint

Force Vector — Two-point control — one hand stabilises the forearm while the other drives the wrist into flexion, extension, or deviation

Vulnerability — Small joint with limited muscular protection makes it susceptible to sudden, low-force submissions

Position & Entry

From any grip exchange — During grip fighting, isolate the opponent's wrist with two-on-one control and apply sudden flexion or rotation

From guard (gi) — When opponent posts a hand on the mat or chest, trap the wrist and apply downward pressure for the wrist lock

From mount or side control — Opponent posts to escape, trap the wrist against the mat and apply the lock

Variants

Standard wrist lock (kote gaeshi) — two-handed rotational lock on the wrist

Gooseneck wrist lock — flexion lock bending the wrist down toward the forearm

Standing wrist lock — applied during grip fighting or a standing exchange

Ground wrist lock — catching the opponent's posted hand from mount, side control, or guard

Training Notes

✓Submissions from prone control attack the opponent when they are face-down — a vulnerable position that exposes the neck, arms, and legs to locks and chokes (Danaher, New Wave Jiu Jitsu, 2020)

✓The prone position limits the opponent's defensive options: they cannot see the attacker, cannot use their arms effectively, and cannot hip escape

✓Common attacks from prone control: rear-naked choke (after rolling to back control), arm locks on the exposed posted arm, wrist locks, and ankle locks

✓The transition from prone to submission is a key skill: catch wrestlers and folkstyle wrestlers specialise in attacking from the top position against a face-down opponent

✓The wrist lock from prone control attacks the hand that the opponent plants on the mat to push up — the posted hand is hyperextended using body weight

✓Prone control rides (chest-to-back, side ride, cross-body ride) maintain the position while setting up submissions

✓The prone opponent's instinct is to push up to hands and knees — this pushing action exposes the arms and wrists for immediate locks

Common Mistakes

!Not maintaining control while attacking — the prone opponent will scramble to escape; maintain chest-to-back contact throughout

!Attempting submissions before establishing control — secure the riding position first, then identify which limbs are vulnerable

!Not using body weight — from prone control, body weight is your primary tool; lifting off to apply a technique allows the opponent to move

!Ignoring the back-take — from prone control, the back take is often the highest-percentage option; don't skip it for lower-percentage locks

!Not training the prone position — many grapplers neglect top-turtle and prone attacks; this leaves significant opportunities untrained

!Applying locks without knowing which arm is posted — read the opponent's body position before committing to an attack

!Staying in prone control too long without progressing — use the position to attack or transition; stalling from prone control wastes the opportunity
