ABSTRACT:
A combination stance limiting and muscle flexing device particularly useful in karate training. The device consists of a flexible strap which is adjustable in total length, connected at opposite ends by means of swivel connectors with cuff assemblies to be worn on the legs or arms of an individual. The flexible strap is made up of two length-adjustable portions connected by an elastic portion. The length-adjustable portions form loops at their free ends which receive the swivel connectors and are adjusted by folding the strap material over on itself at selected positions along the body of the strap material. The strap material is made of Velcro material which easily attaches and detaches to allow for easy adjustment. The elastic portion of the strap allows a limited stretch capability of about two inches. Once the student's limbs are at the optimum distance and properly positioned as determined by the unstretched length of the flexible strap, he may expand further against the resistance of the elastic, thus flexing the appropriate muscles and joints. The cuff assemblies are worn on the student's wrists or ankles, and have "D" rings providing an attachment point for the swivel connectors at opposite ends of the flexible strap. The cuff assemblies are made up of an outer cuff, preferably constructed of Velcro material, and an inner cushioning liner, preferably made of neoprene rubber and are attached to the respective limb by wrapping around and attaching the outer cuff to itself by means of the Velcro material. The swivel connectors allow for the switching of karate positions while wearing the device without binding.
