In boxing, a check hook is employed to prevent aggressive boxers from lunging in. There are two parts to the check hook. The first part consists of a regular hook. The second, trickier part involves the footwork. As the opponent lunges in, the boxer should throw the hook and pivot on his left foot and swing his right foot 180 degrees around. If executed correctly, the aggressive boxer will lunge in and sail harmlessly past his opponent like a bull missing a matador. This is rarely seen in professional boxing as it requires a great disparity in skill level to execute. Floyd Mayweather, Jr. demonstrated a picture perfect example of this punch against Ricky Hatton in their 2007 encounter. Ricky Hatton was caught with the check hook as he was lunging in; Hatton continued forward as he was knocked off balance and proceeded to ram his head into the ring post as Floyd Mayweather stepped out of harm's way. When interviewed, Mayweather stated that he was taught the check hook in the Michigan amateurs.
