Abstract: A device and method for helping a golfer to execute a correct golf swing and to establish or "groove" that swing. The device comprises an arcuate guide member which is dimensioned and supported to extend along the path of travel of a golfer's hands throughout the execution of a full and correct golf swing. The arcuate guide member includes a channel which slidably retains a rider, the rider being detachably connected by a strap to a glove worn by the golfer and gliding along the channel as the swing takes place. Should the golfer's hands tend to leave the plane of the correct swing, or should an undesirable twisting action of the hands and/or wrists occur, the strap will become taut and exert a correcting force.
