Introduction to the Rear Gooseneck
The rear gooseneck is a wrist lock that renders the opponent completely helpless when executed correctly. This technique exemplifies how proper body positioning and structural control can neutralize an opponent regardless of size or strength differentials.
Core Mechanics: Head and Body Positioning
The instructor's head rests on the opponent's shoulder, protecting her own head from strikes while isolating the opponent's upper body. The opponent's body is pinned against a wall or similar barrier, eliminating any escape angle or rotational movement.
Arm Trapping and Forearm Control
Both of the instructor's forearms squeeze together to trap the opponent's forearm, with pressure applied directly to the knuckles rather than the fingers to prevent slipping. The opponent's elbow is completely blocked by the instructor's stomach, while the back controls the opposite side, creating total isolation.
The Gooseneck Principle
The fundamental concept of a gooseneck involves forcing the opponent's palm toward their forearm. This same principle applies across multiple contexts—aikido applications, eye locks, and rear-body positions—allowing practitioners to understand and execute numerous variations through a single mechanical framework.
Wrist Collapse: The Critical Factor
Maintaining a collapsed wrist position allows control with minimal strength; once the opponent straightens their wrist, escape becomes possible unless the instructor possesses superior strength. Continuous pressure on the collapsed wrist throughout the technique ensures control without relying on muscular force.
Application for Size Disadvantage
The rear gooseneck is an exceptionally effective finishing position for smaller practitioners facing larger opponents, as it neutralizes strength advantages entirely. In self-defense scenarios, particularly those involving significant size differentials, practitioners should prioritize decisive wrist breaks rather than prolonged holds.
Training Protocol and Safety
Partners should resist using speed when escaping; they should apply full strength pressure only. This allows the executing partner to control the technique safely while the resisting partner avoids injury from the accelerated forces of a speed-based escape.
Pressure Application and Finishing
Pressure should be applied precisely at the knuckle zone, avoiding the fingers where slippage occurs. By isolating the elbow completely, the instructor can generate significant wrist damage through minimal force, requiring only two fingers of pressure when mechanics are executed correctly.

The Rear Gooseneck is easily the most powerful wristlock I've ever encountered in all of my years of martial arts. This vid shows The Mechanics of the Rear Gooseneck. There are lots of details so I must talk a lot, but when using leverage against stronger opponents, details are everything. Notice that even when Peter provides 100% resistance, he is still helpless inside the Rear Gooseneck despite the size and strength difference. Feedback from law enforcement and martial artists would be most appreciated.
