ABSTRACT:
A versatile bidirectional isometric exercise device is provided in the form of an inflatable flexible exercise ball, about 18 inches in diameter, fitted with a pair of looped handles, secured to diametrically opposite points of the ball, through which arms or legs can be placed for performing specialized exercises that use the ball in a tension mode. The ball is only partially inflated so as to provide soft compliant accommodation to various body surfaces, and can be utilized bidirectionally, i.e. either in compression or in tension, in conjunction with various body parts such as hands, legs, knees, feet, etc., for a broad array of isometric muscle exercises directed to overall body strengthening, particularly for persons prone to and/or desiring protection from the effects of osteoporosis. A sequence of recommended exercises may be depicted directly on the surface of the ball. Attachment of the handles to the main ball portion may be made by sonic welding. In one embodiment an internal bladder is enclosed in a fabric cover, and in one version of this, two hemispheric portions are formed to each provide an integral looped handle. A pressure gauge and/or user-adjustable alarm indicator may be provided to indicate muscular force applied in either compression or tension.
