A collapsible golf swing training tool employs a plurality of elliptical blades, attached to a weighted shaft, to capitalize on air resistance, to aid in developing the muscle memory and strength required for a smooth and consistent golf swing. Cylindrical weights can be added or removed to meets the user's needs and may be positioned such that their linear axis is parallel or perpendicular to the linear axis of the tool. For convenience the blades are collapsible for easy storage within a golfer's golf bag.
