Abstract: A golf trainer characterized by a ground support (4) having a ring (6) on which is positioned a ring (3), with the inclusion of bearings formed as slide runners (12) between the two rings (3) (6) to permit the selective turning of the upper ring (3) with respect to the lower (6) about a substantially vertical axis, the upper ring (3) being attached by means of pivots (7), to a base or platform (1) which may thus tilt, from a position parallel to the ground to an inclined position, so that the base or platform (1) may turn and moreover may be inclined with respect to the ground.
