Golf swing training apparatus disclosed includes a base, an upright support frame, rotary guide arm assembly at the top of the support frame establishing a reference axis of rotation at an inner arm portion and having an outer end flexibly coupled to the club head so that as the club is swung it is confined to a swing plane perpendicular to the reference axis of rotation. There is adjustment in frame height and angle of incline for the reference axis of rotation as well as adjustment in the drag. There is also a tensioning feature to dampen the inertia mass during the stroke.
