摘要: A light weight plastic "pan-like" device is attached to any sports swung implement. When attached, the implement in of normal stroking motions. The produces air resistance against intended motion. With regular, repetitive exercise arm, shoulder, and back muscles are strengthened. Functional achieved aerodynamic drag. devices may be adjustable for a greater or lesser amount resistance. quickly locked into place with simple attachment means. maximize per unit surface by minimizing optimizing capturing features.
