Abstract: Embodiments of the present invention are directed to systems and methods for alerting a golfer when he or she moves his or her head during a swing or stroke. According to an exemplary embodiment, a golf training aid comprises a movement detection mechanism and an alerting system. The training aid can comprise, for example, a support structure, such as a tube, and a weighed object, such as a ball. The weighted objet is located on or in the support structure, and the support structure is coupled to the golfer's headwear, such as a hat or visor. The weighted object is initially settled in a receiving portion of the support structure, but displaces when the golfer moves his head. The displacement alerts the golfer to the head movement, allowing the golfer to reduce or eliminate such movement from his or her golf game.
