Armbar From Behind
When engaged with an opponent, the back mount position will always provide security and dominance in the fight. the opponent has not real offensive options and can only try to avoid submissions and strikes or try to slip through your grasp. This armbar setup can be good during either one of these situations. It is a quick and powerful submission that can surprise the opponent from the back mount.
This armbar set-up was seen in the Palhares Vs. Salaverry fight where Palhares caught his opponent in this submission with, what apeared to be, flawless technique. He makes it look easy in the video below but this is a more advanced Brazilian Jiu-Jitsu move that takes much practice to use in a real match. With that said HERE is a link to a page with some information of the back mount position in general.
Setting Up the Armbar
Of course to start this submission you must first choose an arm to attack, for clarity’s sake lets say you decide to attack the opponent’s left arm. From a good back mount your left arm should be under the opponent’s left and your right arm should be over his right shoulder locking the opponent in position.
Now the right arm is removed and put on the left side of the opponent’s head and takes control of the opponent’s left wrist. Your left arm now reaches up from underneath the opponent’s arm, grabbing your wrist. This completes a Kimura grip, giving you control of the opponent’s arm.
To complete the submission your body needs to shift to the side of the arm that is being attacked so that the whole body can put force on it. To do this your legs need to shift first. The leg on the side of the arm that is being attacked is passed across the opponent’s waist. The other leg is swung behind the opponent, over his head, and placed across his chest to secure him.
Finishing this submission is a piece of cake once you get the opponent on his back, it is getting him there successfully that is the challenge. To complete this submission there is a lot of shitting of position happening. Experience in BJJ and the back mount position help with that exponentially because of the sly and speedy change of position needed to avoid a counter.
The time where you shift from his back to the final armbar position is when your opponent is most likely to weasel his way out of the submission attempt. To avoid this speed can make the opponent not realize what happening until its too late if he is not very experienced. Also The leg that is placed across his chest needs to be placed there and stamped down with force to secure the opponent. By using this leg to pin the opponent to the ground it eliminates the possibility of him rolling into you to avoid the submission.
From here the legs hold the opponents upper body to the ground while your arms hold his arm to your chest/upper body. The hips are raised up hyper extending the elbow and causing excruciating pain.
Below is a video explaining the technique from start to finish.
