Abstract: A golf swing aid fits around the wrists of a golfer and assists in keeping the golfer's wrists together during a golf swing. The golf swing aid comprises a first wrist strap having cooperating fasteners at opposite ends for releasably securing it around a golfer's wrist. An elastically stretchable second wrist strap overlies the first strap and its opposite ends are secured to the first strap to form an elastically stretchable loop that faces the golfer's other wrist. The second strap can be stretched to loop around the golfer's other wrist when the golfer grips a golf club. The second strap, when looped around the golfer's other wrist, stays under tension to provide an elastic return force that resists any tendency of the golfer to separate his wrists during a golf swing.
