Abstract: A putting training device and method for training a golfer's muscles to learn, recall and follow the proper putting swing. The training device has a rigid guide rail from which a vertical plate extends perpendicularly. The face of the putter head is held against the vertical plate to insure the face is held perpendicular to the intended trajectory of the golf ball. As the putt swing is made, the plate slides in channel of guide rail, tensioned by elastic band or similar stretchable material. The method is repeated until a swing of similar trajectory can be made without the aid of the putting training device. The device may include a gripping device on the guide rail to secure the training device to the putting surface.
