Abstract
Abstract The invention is an improved apparatus for practicing the martial arts, such as the various forms of Karate, known by various names and taught in several styles. The practice bag of this invention provides a means for sharpening reflexes and coordination without the need of a skilled human opponent. The practice bag consists of a covered cylindrical bag with four cylindrical-like apertures therethrough, said apertures being lined, said lining being suitably fastened to the bag at each point where the cylindrical-like apertures interface with cover of the bag. A center target piece is attached to the exterior of the cover of the bag and more-or-less centrally located between the apertures on one side of the bag. The bag is filled with a suitable material which surrounds the cylindrical-like apertures passing through the bag. Cable-like attachments to the top of bag support it from above. Rod-like poles with padded ends are extended through each of the four cylindrical-like apertures to simulate the arms and legs of an opponent. The simulated arms and legs can be manipulated for practice of the martial arts.
