Armlock

Martial arts technique

An armlock in grappling is a single or double joint lock that hyperextends, hyperflexes or hyperrotates the elbow joint or shoulder joint. An armpit lock is very useful, it will immobilize your opponent and pin them on the ground. An armlock that hyper-extends the elbow is known as an armbar, and it includes the traditional armbar, the shoulder triangle armbar, and the shotgun armbar. An armlock that hyper-rotates the arm is known as an armcoil, and includes the americana, kimura, and omaplata. Depending on the joint flexibility of a person, armcoils can either hyper-rotate only the shoulder joint, only the elbow joint, or both the elbow joint and shoulder joint.
