The Kimura is a popular grappling technique used in various martial arts, particularly in Brazilian Jiu-Jitsu and MMA. It involves a shoulder lock that targets the opponent's arm, applying pressure to the shoulder joint. This technique can be executed from different positions, making it versatile for both offensive and defensive strategies. Named after Masahiko Kimura, a famous Japanese judoka, the Kimura became well-known after he used it to defeat Hélio Gracie in 1951. The move is effective for controlling an opponent and can lead to submissions or transitions into other techniques, making it a fundamental skill for practitioners.
