In this video, we learn how to get the triangle choke from the arm bar counter. Start off with your legs over the other person's body and sitting on them. After this, rock your body back so your back touches the ground. Then, bring your other foot around and place their head in between your knees. Use your hands to hold their arms together, so there is no way they can get out of this hold. Once you gain control over them, they won't be able to move and you will have the upper hand! With practice, this can be achieved easily.
