A putter training apparatus and method of use are provided. In one form, a putter training apparatus includes a putter head generally formed as a mallet attached to a standard golf shaft. The putter head includes an opening through the vertical distance of the putter head, generally centered in the putter head. The putter head further includes a standard golf ball, generally centered within the opening. The golf ball is attached to an extension and retraction system comprising two spherical seats inserted in the heel side and toe side of the opening and two ligaments connecting the spherical seats to the golf ball. The extension and retraction system allows the golf ball to extend from the opening during use, and remain visible to the user through the opening, as long as the user employs a smooth, in line, and in tempo putting stroke.
