Abstract: The present invention is a piece of exercise equipment designed to train and condition sport-specific muscle groups used during a swinging motion, as in golf. It is comprised of a mechanical linkage, with at least six free-moving joints, so that it effectively simulates a wide variety of golf swings without the need for complex adjustments and provides for smooth and even distribution of resistance to the various muscle groups involved in the swinging motion. It includes a resistance mechanism, such as a pulley system linked to two one-way hydraulic cylinders. This allows a user to simultaneously practice swing form and technique while also strengthening and conditioning the specific muscles needed for the sport.
