A golf training device that is equally useful in developing a putting stroke and a swing stroke. A club head is severed in the middle and a ball is rotatably secured between the head segments. A circumferential line is applied at the ball's equator defining a plane perpendicular to a line about which the ball rotates. Rotation of the ball is employed for training certain strokes or segments of strokes, and the circumferential line is employed for training certain strokes or segments of strokes.
