Compensatory Acceleration Training (CAT) is a weightlifting technique where a person accelerates the bar as leverage improves throughout the movement that is used to develop explosive strength. Dr. Frederick C. Hatfield wrote about the concept of compensatory acceleration training in 1982. Hatfield claimed the following benefits for CAT: greater efficiency, fewer injuries and greater explosive power. Hatfield defined compensatory acceleration as "pushing as hard as possible throughout the movement", i.e. a high action velocity. Years later a study by Jones et al. supported Hatfield's contentions by finding that CAT was superior to traditional standard weight training for developing upper body strength and power. The technique was perfected by bodybuilding legend, Scott Bennett
