What is Rotator Cuff in BJJ?
Quick Definition
The group of shoulder muscles and tendons targeted by kimuras and americanas.
Full Explanation
The rotator cuff is a group of four muscles and their tendons that stabilize the shoulder joint. Shoulder lock submissions like the kimura and americana attack the rotator cuff by rotating the shoulder beyond its safe range of motion. Rotator cuff injuries are among the most common injuries in BJJ, ranging from minor strains to tears requiring surgery. Strengthening the rotator cuff through prehabilitation exercises helps prevent these injuries.
