Abstract
A swing motion device for providing exercise and training has a plurality of collapsible vanes mounted on a shaft that an athlete may grip and swing through the air. The vanes provide air resistance against which the athlete's muscles must work. Each vane may comprise a foldable wire framework covered with a bag-like fabric sheath. When the vanes are collapsed, the device assumes a compact shape that facilitates transport and storage.
