Guy tries to break opponent’s shoulder with a BJJ technique in a street fight.

The kimura lock, also called double wristlock in catch wrestling, and chicken wing or gyaku ude-garami in judo, is a grappling submission hold of uncertain origin, being catch wrestling and judo the likely authors of the position.

In Brazilian jiu jitsu, the submission bares the name of Kimura after the famous Masahiko Kimura who defeated Helio Gracie with this lock on the 23rd of October, 1951.

The submission relies on isolating the shoulder and elbow joints with the use of a double wrist grip which allows for the attacker to apply leverage against both of these joints (though mainly the shoulder).

Helio saw this match as a retirement fight, he was 39 years old (Kimura was 34). He was quoted after the bout saying that he knew he had very few chances to win against the famous Japanese, but he saw it as a chance to test his skill. [source : bjjheroes.com]

“This altercation happened over a 6 pack of beers. This a** wipe thought I had drank his beers, so he started accusing me and later started to call me names. Then the a** wipe threw a punch, so I kicked the s*** out of him then got him in a submission. Only half of the video was recorded but the Kimura was all that mattered!“

6 tips to securing the Kimura from a closed guard position:

1. Keep control of his body with your legs by bringing your knees close to your chest.
2. Keep his hand away from his body or any clothing that he can grab onto.
3. Keep his arm at a 90 degree angle.
4. Bring your hips out a little bit to create more leverage for the submission.
5. Bring his wrist up and across his back, toward his other shoulder.
6. Keep his tricep close to your body. [source : 1001 Submissions]
