Abstract: A method of improving the putting stroke of a golfer using a putter as a training device, said putter having a club head and in one embodiment an attachment for the same. The club head has faces or edges defining a body of a predetermined thickness to which a shaft is attached. Within the body of the head there is provided a recess in a form which opens into the rear face of the head or as a closed aperture completely defined within the body which is of marginally greater dimensions than, and adapted to receive an object such as a conventionally sized golf ball. The recess or aperture can be disposed of substantially centrally of the head so that the “sweet spot” can be substantially centrally disposed of said recess or aperture. Ideal toe-heel weight distribution can be achieved in this manner. The club, which is typically a putter, can be used as a practicing aid by swinging the same proximate a surface when the articles or objects are disposed within said recess or aperture.
