The Kimura lock is one of the most common submissions. Therefore, it is one of the first that you learn on your BJJ journey.
This technique was named after Masahiko Kimura, who used this move to defeat Helio Gracie. The kimura lock consists of putting pressure on the shoulder joint, which can be hard to escape if you don’t react in time. Kimura is used in many other grappling martial arts and it can be done from many different positions. Below are the most 3 common positions for a kimura.
1. Closed Guard
When your opponent puts his hands on the mat or you force him, it is time for the kimura technique. Grab his wrist, open your hips and reach over his triceps, through his arm and grab the arm that was on the wrist. The next move is to shoulder switch while holding his triceps tightly to your chest. To finish the submission, move his elbow towards his head. It’s important that you put your leg on his back to prevent him from rolling out the Kimura attack.
