Abstract
A martial arts kick and strike bag made up of cylindrical and conic sections. A cylindrical section will effectively receive blows delivered in a plane orthoginal to the axis of the practice bag. Blows delivered along a rising incline with respect to the axis of the bag will be most effectively received by the wall of the conic section. Blows are most effectively received when striking the wall of the bag at an impact angle of approximately 90.degree.. The selected angles of the bag walls with respect to the axis of the bag minimize reaction forces such as might result from rising striking blows delivered to prior art, cylindrical, training bags.
