Armlocks. One of the most effective techniques


Armlocks have long been considered one of the most effective techniques in the grappling arts, including Brazilian Jiu-Jitsu, Judo, and submission wrestling. With the ability to incapacitate an opponent through pain or injury, armlocks are an essential part of any practitioner's arsenal. In this article, we'll explore the history, mechanics, and various types of armlocks to provide a comprehensive understanding of this powerful submission technique.

Historical Background

Armlocks have been a part of martial arts for centuries, with evidence of their use dating back to ancient civilizations such as Greece and Rome. The technique was further developed in Japan through the practice of traditional Jujutsu, which later gave birth to modern martial arts like Judo and Aikido. In the early 20th century, Japanese practitioners brought these techniques to Brazil, where they were adopted and adapted by the Gracie family to create Brazilian Jiu-Jitsu.

Mechanics of Armlocks

Armlocks work by isolating an opponent's arm and applying pressure to the elbow joint or the shoulder joint, forcing it to bend in an unnatural direction. This pressure can cause immense pain and may result in a dislocation or even a broken bone if the opponent does not submit. To successfully execute an armlock, it's essential to have proper control over the opponent's body, ensuring they cannot escape the submission attempt.

Types of Armlocks

  1. Straight Armlock (Juji-Gatame): Also known as the armbar, this is perhaps the most well-known armlock in Brazilian Jiu-Jitsu. The attacker traps the opponent's arm between their legs, controlling the wrist and using their hips to apply pressure to the elbow joint. This armlock can be executed from various positions, including the mount, guard, and side control.

  2. Kimura (Gyaku Ude-Garami): As previously mentioned in our article on the history of the Kimura, this technique is named after the legendary judoka Masahiko Kimura. The Kimura is a double-joint armlock that targets the shoulder joint by bending the opponent's arm behind their back and using a figure-four grip to apply pressure.

  3. Americana (Ude Garami): Also known as the keylock or paintbrush, the Americana is a shoulder lock that involves pinning the opponent's arm to the mat and bending it at a 90-degree angle. The attacker then uses a figure-four grip to apply pressure to the shoulder joint, forcing the opponent to submit.

  4. Omoplata: This armlock is a variation of the Kimura but is executed using the attacker's legs to control the opponent's arm. The technique involves trapping the opponent's arm between the attacker's legs and using their hips to apply pressure to the shoulder joint.

  5. Straight Armlock from the Guard (Armbar from Guard): This variation of the straight armlock is executed from the guard position, with the attacker using their legs to break the opponent's posture and isolate their arm. By controlling the wrist and applying pressure with the hips, the attacker can force the opponent to submit.


Armlocks are a critical component of any grappler's skillset, and their effectiveness has been proven time and time again in both competition and self-defense situations. By understanding the history, mechanics, and variations of armlocks, practitioners can develop a deeper appreciation for these techniques and become more well-rounded martial artists. Whether you're new to grappling or an experienced competitor, incorporating armlocks into your training will undoubtedly improve your overall game and increase your chances of success on the mat.
