Abstract: One embodiment includes a swing aid to help athletes (e.g., golfers, batters, or tennis players) learn how to properly hinge their wrists during a swing of a golf club, bat, or racquet. A device comprises a plurality of weights (e.g., balls) included in a conduit. In a low first swing position the balls are located together at a distal end of the conduit. In a high second swing position the balls are located together at a proximal end of the conduit. When transferring from the second position to the first position the balls make a first sound (which indicates improper wrist action) or a second plurality of sounds (which indicates proper wrist action) based on when the user rotates the device about the proximal end of the conduit (e.g., unhinges the wrist). Other embodiments are described herein.
