Omoplata
The Omoplata is a shoulder lock submission that uses the opponent’s arm and shoulder joint to create torque, forcing a tap. The submission is applied by trapping the opponent's arm with your legs and rotating your body, leveraging the opponent’s shoulder against their natural range of motion. It is a versatile technique, often used as both a submission and a tool to sweep or transition into dominant positions.
The Omoplata is most effective when the opponent’s arm is isolated, and you can control their posture and Fundamentals/Base while using tight connections and proper angles to maximize pressure on their shoulder. It is also a highly versatile tool that can lead to sweeps, submissions, or positional advancements.
