The crucifix position is a ground grappling position that involves being perpendicularly behind the opponent, chest against back, and controlling the opponent's arms. One of the opponent's arms is controlled using the legs, and the other using the arms, hence effectively putting the opponent in a position resembling a crucifix. A top variation can also be applied from side control.^[1]

This position allows for elbow strikes to the head, or if the opponent is wearing a gi, it allows for a collar strangle called the crucifix choke (in Judo known as jigoku jime, 地獄絞, "hell strangle").^[2] It is also possible to have the crucifix position in such a way that a crucifix neck crank can be applied.
