Resistance-based exercise device

Abstract

A resistance-based exercise device comprised a bar with a first engagement plate fixed to its first distal end and a second engagement plate fixed to its second distal end. The first and the second engagement plates have one or more openings for detachably engaging one or more resistance bands of varying resistance level by a coupler.

         2 . The resistance-based exercise device as set forth in  claim 1 , wherein:
 the one or more openings are oriented at a 180-degree separation.   
     
     
         3 . The resistance-based exercise device as set forth in  claim 1 , wherein:
 the one or more openings are oriented at a 90-degree separation.   
     
     
         4 . The resistance-based exercise device as set forth in  claim 1  wherein:
 the bar has a compact form factor, comprised of an elongated, cylindrical piece. 
 
     
     
         5 . The resistance-based exercise device as set forth in  claim 1  wherein:
 the one or more openings are equally distanced from the center, and are uniformly disposed between the center, disk peripheral edge, and one another. 
 
     
     
         6 . The resistance-based exercise device as set forth in  claim 1  wherein:
 the one or more openings are unequally distanced from the center, and are non-uniformly disposed between the center, disk peripheral edge, and one another. 
 
     
     
         7 . The resistance-based exercise device as set forth in  claim 1  wherein:
 the one or more openings have different configurations. 
 
     
     
         8 . The resistance-based exercise device as set forth in  claim 1 , wherein:
 an opening of the one or more openings has a first size; and   a next opening of the one or more openings has a second size.   
     
     
         9 . The resistance-based exercise device as set forth in  claim 1  wherein:
 the coupler detachably engaged with an opening of the one or more openings freely slides within the opening during a range of motion of exercise. 
 
     
     
         10 . The resistance-based exercise device as set forth in  claim 1  wherein:
 the first engagement plate and the second engagement plate are oriented perpendicular a longitudinal axis of the bar. 
 
     
     
         11 . The resistance-based exercise device as set forth in  claim 1  wherein:
 the first engagement plate and the second engagement plate are parallel, with orientation of the one or more openings perpendicular to a longitudinal axis of the bar. 
 
     
     
         12 . A compact bar apparatus, comprising:
 a metal barbell;   a first and a second metal disks that includes a center that is welded to each distal end of the barbell;   the first and the second metal disks have one or more openings surrounding the center for detachably engaging one or more resistance bands of varying resistance level.   
     
     
         13 . The resistance-based exercise device as set forth in  claim 11 , wherein:
 the one or more openings are oriented at a 180-degree separation.   
     
     
         14 . The resistance-based exercise device as set forth in  claim 11 , wherein:
 the one or more openings are oriented at a 90-degree separation.   
     
     
         15 . A resistance-based exercise device, comprising of:
 a single, integral piece having:   an elongated cylindrical bar that has a first distal end and a second distal end;   a first engagement plate configured as a first disk having a first center fixed to the first distal end of the bar;   the first disk includes:   a first set of openings that are disposed on the first disk; and   a second engagement plate configured as a second disk having a second center fixed to the second distal end of the bar;   the second disk includes:   a second set of openings that are disposed on the second disk.   
     
     
         16 . The resistance-based exercise device as set forth in  claim 14 , wherein:
 an opening of the first set of openings has a first size; and   a next opening of the first set of openings has a second size.   
     
     
         17 . The resistance-based exercise device as set forth in  claim 14 , wherein:
 the first set of openings have equal size.   
     
     
         18 . The resistance-based exercise device as set forth in  claim 14 , wherein:
 an opening of the second set of openings has a first size; and   a next opening of the second set of openings has a second size.   
     
     
         19 . The resistance-based exercise device as set forth in  claim 14 , wherein:
 the second set of openings have equal size.   
     
     
         20 . The resistance-based exercise device as set forth in  claim 14 , wherein:
