Adjustable elastic resistance exercise device

Abstract

A flexible band and/or chain is disclosed comprising a plurality of rings, links, or touri. In some embodiments, the links are interlocking In other embodiments, the links are affixed to one another in linear fashion. The links a gripable, and serve as handles for a user needing to target specific muscle groups for exercise by applying tensile force to the chain. The chain stretches. Some variations include detachable handles which can at attached at the ends of the chain or to links forming it.

What is claimed is: 
     
         1 . An isotonic exercise device comprising:

         2 . The isotonic exercise device of  claim 1 , wherein the plurality of elastomeric rings are formed as single integrated piece. 
     
     
         3 . The isotonic exercise device of  claim 1 , wherein each of the plurality of rings in the segment are links interconnected forming a chain. 
     
     
         4 . The isotonic exercise device of  claim 1 , further comprising one or more secondary segments of elastomeric rings detachably affixed to the segment to increase an overall length of the isotonic device. 
     
     
         5 . The isotonic exercise device of  claim 1 , wherein the segment comprises a plurality of single elastic ring(s) detachably affixed to one another by means of connectors. 
     
     
         6 . The isotonic exercise device of  claim 1 , further comprising one or more handles detachably affixed to one of the plurality of elastomeric rings. 
     
     
         7 . The isotonic exercise device of  claim 6 , wherein the handles comprise elastic rings. 
     
     
         8 . The isotonic exercise device of  claim 1 , wherein the segment is formed of a plurality of extruded elastomeric tubes helically wound around one another. 
     
     
         9 . The isotonic exercise device of  claim 1 , wherein each of the rings is shaped as one of a torus, double torus, triple torus, toroidal polyhedron, dupin cyclide, and stretched donut-shape. 
     
     
         10 . The isotonic exercise device of  claim 1 , wherein each of the rings is of uniform outside diameter. 
     
     
         11 . The isotonic exercise device of  claim 1 , wherein one or more of the elastomeric rings are fabricated by a mold or extrusion process. 
     
     
         12 . An isotonic exercise device comprising:
 a flexible elastomeric belt defining a plurality of apertures;   wherein the belt is stretchable by a user applying tensile force to the belt through the apertures with one of a hand and a detachable handle; and   wherein the device is fabricated by a mold or extrusion process.   
     
     
         13 . The isotonic exercise device of  claim 12 , further comprising one or more handles detachably affixed to the belt, each of the one or more handles affixable to one of the apertures. 
     
     
         14 . An isotonic exercise device comprising:
 a plurality of flexible elastomeric bands, each band comprising:
 a first connector affixed to a distal end of the band; and 
 a second connector affixed to the proximal end of the band; 
   wherein each band is detachably affixed to one or more bands from the plurality of elastomeric bands using one or more of the first connector and the second connector.   
     
     
         15 . The isotonic exercise device of  claim 14 , further comprising one or more handles detachably affixed to one of the plurality of flexible bands. 
     
     
         16 . The isotonic exercise device of  claim 14 , wherein the first connector comprises one of a socket, loop, hook, prong, a receptacle for receiving a male connector, fastener, and clip. 
     
     
         17 . The isotonic exercise device of  claim 14 , wherein the second connector comprises one of a socket, loop, hook, prong, a receptacle for receiving a male connector, fastener, and clip.
