Abstract: A golf swing training and exercising device for developing the muscles of a golfer which are associated with a golf swing. The device includes a housing which is secured at an elevated position above a level ground surface. A resistance generating unit is mounted within the housing and imparts a controlled and adjustable resistance to an elongate member which is pivotally secured to the housing. The elongate member is also both pivotally secured at a first location to the housing and at a second remote location to a grip. The grip is capable of being grasped by the golfer in a golf swing stance and the golfer rotates the grip and elongate member in a first resistive direction corresponding to a back stroke and then in a subsequent and second opposite resistive direction corresponding to a follow through swing.
