  • Patent number: 7261653
    Abstract: The present invention provides a training apparatus and method for improving the stance of a golfer throughout the golfer's swing. The apparatus comprises a shaft pivotally connected to a base so that the shaft pivots about a pivot point along a plane to increase or decrease the angle formed by the base, the shaft, and the pivot point. A golfer stands on the base and straddles the shaft so that the leading foot is behind the shaft nearest the pivot point, and the non-leading leg is in front of the shaft thus preventing an over-rotation of a golfer's hips during the performance of a back swing and keeping the golfer's arms in front of the golfer's chest so that the golf club does not become trapped behind the golfer.
