A unique hand grip is provided for a bowling ball wherein the lifting fingers work in unison to provide a single balanced lifting force directed toward the thumb. This is accomplished by use of an appropriately sized elliptical finger cavity which receives a bowler's middle and ring fingers therein. An alternative embodiment encompassing two thumb holes provides two separate grips utilizing the same elliptical cavity to obtain distinct and separate performance characteristics in a single bowling ball. Finally a method is provided for rehabilitating a conventional bowling ball and improving it by the removal of the traditional finger holes therefrom and the addition of an elliptical cavity as a replacement therefor. |
