Swing training aid

Abstract

A swing training device includes a central shaft having a first end and a second end, and a plurality of air resistance blades secured to the central shaft adjacent the second end of the central shaft. Each of the air resistance blades includes a proximal edge secured adjacent the central shaft and a distal edge extending away from the central shaft, wherein each of the air resistance blades includes at least one air hole adjacent the proximal edge. The device preferably includes first and second air resistance blades secured to the central shaft and the blades are pivotally secured adjacent the central shaft for rotation about an axis substantially parallel to a longitudinal axis of the central shaft.
