  • Patent number: 11311790
    Abstract: A compression golf swing training apparatus includes a hitting board mounted atop a framework and configured to move downwardly at the point of impact from the golf club striking the hitting board during a golf swing. Specifically, the downward motion of the hitting board, when struck with a golf club, compresses the compression springs in their holder imitating or replicating the feeling a golfer experiences when taking a divot of golf course grass during a golf swing. The system is reconfigurable and interchangeable with distinct compression spring levels held in their individual spring holders replicating and/or imitating the resistance of the ground the golfer experiences playing on hard, soft, and wet golf course grass conditions.
