What is the Kimura?

The Kimura lock, also called the double wristlock, is a strong submission move used in Brazilian Jiu-Jitsu (BJJ) and mixed martial arts (MMA).

Importance in BJJ and MMA

It helps you control and submit opponents, making it a valuable tool for grapplers and fighters. Learning the Kimura can greatly improve your overall grappling skills, giving you a reliable submission option in both competitions and self-defense situations.

History of the Kimura

Origins in Judo

The Kimura lock comes from judo, where it’s called the “gyaku ude-garami” or reverse arm entanglement. This move was used in judo long before it became popular in BJJ. It controls and submits opponents by twisting the shoulder joint, a principle that hasn’t changed.

Masahiko Kimura vs. Helio Gracie

The Kimura lock became famous on October 23, 1951, when Masahiko Kimura used it to defeat Helio Gracie in a historic match. Kimura, one of the greatest judokas ever, was challenged by the Gracie family to test their Brazilian Jiu-Jitsu against his judo. The match ended with Kimura using the gyaku ude-garami, which the Gracies later named the Kimura in his honor.

Evolution in BJJ

Since it was introduced to BJJ, the Kimura has evolved to fit the sport’s unique style. BJJ practitioners have created many variations and setups for the Kimura, making it a versatile and essential part of grappling. Today, it’s a basic move taught to students of all levels, from beginners to advanced competitors.

Anatomy of the Kimura Lock

Key Parts

The Kimura lock has several key parts that work together to create a strong submission. These include:

  • Grip: You secure a figure-four grip on the opponent’s arm, with one hand holding their wrist and the other hand gripping your own wrist.

  • Positioning: Proper body positioning is crucial to maximize leverage and control. You must position your body to isolate the opponent’s arm and shoulder.

  • Leverage: By using your body weight and positioning, you apply pressure to the opponent’s shoulder joint, forcing it into an unnatural and painful position.

How It Works

The Kimura lock works by twisting the shoulder joint beyond its normal range of motion. This is done by:

  • Isolating the Arm: Your grip and positioning isolate the opponent’s arm, preventing them from using their body to defend.

  • Rotating the Shoulder: You use your body to rotate the opponent’s shoulder joint, creating immense pressure on the ligaments and tendons.

  • Applying Force: By leveraging your body weight and positioning, you apply force to the shoulder joint, causing pain and potential injury if the opponent does not submit.

Basic Kimura Technique

Step-by-Step Guide

Doing the Kimura lock requires precision and attention to detail. Here’s a step-by-step guide to performing the basic Kimura from the guard position:

  1. Secure the Grip: From the guard position, reach over your opponent’s arm and secure a figure-four grip. Your right hand should grab their wrist, and your left hand should grab your own wrist.

  2. Break the Posture: Use your legs to break your opponent’s posture, pulling them forward and off balance.

  3. Hip Escape: Perform a hip escape to create an angle, positioning your body perpendicular to your opponent.

  4. Isolate the Arm: Use your legs to trap your opponent’s arm, preventing them from defending.

  5. Apply the Lock: Rotate your body and use your arms to apply pressure to the opponent’s shoulder joint, forcing them to submit.

Common Mistakes to Avoid

When doing the Kimura, it’s important to avoid common mistakes that can weaken the move:

  • Poor Grip: Make sure your figure-four grip is secure and tight. A loose grip can let your opponent escape.

  • Incorrect Positioning: Proper body positioning is crucial. Make sure to create an angle and isolate the opponent’s arm effectively.

  • Lack of Control: Maintain control of your opponent’s posture and arm throughout the move. Losing control can result in a failed submission attempt.
