Armlock

An armlock is a grappling technique that manipulates the elbow or shoulder joint through hyperextension, hyperflexion, or hyperrotation. Armpit locks immobilize and pin opponents. Armbars hyperextend the elbow, encompassing variations like the traditional armbar. Armcoils, such as the Americana, Kimura, and Omaplata, hyperrotate the arm, affecting either the shoulder, elbow, or both, based on the individual's joint flexibility. These joint locks are utilized in various martial arts and grappling sports.
