Abstract

An exercise fitness system involves an apparatus comprising a rigid movable booster bar having two flexible elastic elements attached to the booster with an attachment. The attachments are spaced from each other and configured to allow winding the elastic element upon the booster bar by rotating the booster bar. Each flexible elastic element comprises at least two stages of flexible shock cords, with the stages disposed serially along the length of the flexible element, with adjacent stages having a different elastic stiffness.

Claims

exact text as granted — not AI-modified
1 . An exercise apparatus comprising:
 a rigid movable booster bar;   two flexible elastic elements, each attached to the booster bar at a near end with an attachment, the attachments spaced from each other and configured to allow winding the elastic element upon the booster bar by rotating the booster bar, and to allow a gripping region on the booster bar,   each flexible elastic element comprising at least two nonlinear flexible shock cord stages, with each stage having one or more flexible shock cords, and with at least two stages having a different stiffness,   the stages attached to each other end to end so that they are disposed serially along the length of the flexible element, such that when the element is stretched less stiff stages are initially stretched more than more stiff stages, and as stretching continues and less stiff stages approach stretching limit, stretching is transferred to more stiff stages by more stretching in more stiff stages,
 a distal end of each flexible element configured for a moving or fixed attachment to allow stretching of the flexible element. 
   
   
   
       2 . An exercise apparatus as in  claim 1  wherein the stages comprise one or more flexible shock cords. 
   
   
       3 . An exercise apparatus as in  claim 2  wherein two stages with different stiffness have a different number of shock cords. 
   
   
       4 . An exercise apparatus as in  claim 2  wherein two stages with different stiffness comprise shock cord strands of a different stiffness. 
   
   
       5 . An exercise apparatus as in  claim 1  wherein a distal end of each flexible element is attached to a fixed object. 
   
   
       6 . An exercise apparatus as in  claim 1  wherein a distal end of each flexible element is attached to an opposing member. 
   
   
       7 . An exercise apparatus as in  claim 6  wherein the opposing member is movable. 
   
   
       8 . An exercise apparatus as in  claim 6  wherein the opposing member is a flexible strap with the distal ends attached to either end of the strap. 
   
   
       9 . An exercise apparatus as in  claim 8  wherein the flexible strap is elastic or non-elastic. 
   
   
       10 . An exercise apparatus as in  claim 6  wherein the opposing member is a nonflexible bar or platform. 
   
   
       11 . An exercise apparatus as in  claim 10  wherein the opposing member is configured the same as the booster bar. 
   
   
       12 . An exercise apparatus as in  claim 1  wherein the stages are attached to each other by one or more of knots, sewing, glue, fusion, clamps, ties, tape wrapping, and molded structures. 
   
   
       13 . An exercise apparatus as in  claim 8  wherein each flexible element is attached the ends of the strap using a knot fastener. 
   
   
       14 . An exercise apparatus as in  claim 13  wherein the knot fastener has self tightening configuration with the strap passing through loop, twice around both legs of the, down through the loop around and again through the loop, and under itself where it passes twice around both legs. 
   
   
       15 . An exercise apparatus as in  claim 1  wherein at least one stage is constructed of multiple shock cords in a helical pattern around each other. 
   
   
       16 . An exercise apparatus as in  claim 1  wherein the booster bar comprises a pad disposed around the bar at a center portion of the bar where it does not interfere with the winding of the elastic elements. 
   
   
       17 . As exercise apparatus as in  claim 1  wherein the booster bar comprises handles at each end of the booster bar that extend beyond the ends of the booster bar and can be flexed to form levers to resist twisting of or apply torque to the booster bar. 
   
   
       18 . An exercise apparatus as in  claim 8  wherein the flexible strap comprises two flexible loops separated by a flexible middle portion. 
   
   
       19 . An exercise apparatus comprising:
 a rigid movable booster bar;   two flexible elastic elements, each attached to the booster bar at a near end with an attachment, the attachments spaced from each other and configured to allow winding the elastic element upon the booster bar by rotating the booster bar, and to allow a gripping region on the booster bar,   each flexible elastic element comprising at least two nonlinear flexible shock cord stages, with at least each stage having one or more flexible shock cords, and with at least two stages having a different stiffness with at least one stage having at least two shock cords in a helical pattern around each other,   the stages attached to each other end to end so that they are disposed serially along the length of the flexible element, such that when the element is stretched less stiff stages are initially stretched more than more stiff stages, and as stretching continues and less stiff stages approach stretching limit, stretching is transferred to more stiff stages by more stretching in more stiff stages,   a distal end of each flexible element configured for attachment to both ends of a flexible strap, the attachment at each end by a knot fastener that has self tightening configuration with the strap passing through loop, twice around both legs of the, down through the loop around and again through the loop, and under itself where it passes twice around both legs,   the booster bar having a pad disposed around the bar at a center portion of the bar where it does not interfere with the winding of the elastic elements and having handles at each end of the booster bar that extend beyond the ends of the booster bar and can be flexed to form levers to resist twisting of or apply torque to the booster bar.   
   
   
       20 . An exercise apparatus as in  claim 19  wherein the flexible strap comprises two flexible loops separated by a flexible middle portion.
