Abstract: A golf swing stance trainer has a hub and a central telescoping arm connected to the hub. Side telescoping arms are connected to the hub for swinging outward to positions perpendicular to the central arm. The hub has ground-engaging cleats on a lower surface. The central arm is selectively extended outward for position with respect to a ball position. The side arms are selectively extended outward to indicate desired foot positions. The central arm has an extension with a pivot for sliding outward from the central arm for training position and direction of a golf ball and direction and extent of a swing. Arm extensions are related to an individual user and club selection. The arms are telescoped inward and the side arms are swung inward for carrying. The hub includes a hinge rod with a central receive through which a connected on the central arm slides.
