     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring now to FIGS. 1 through 4A, the isometric push-up machine of the present invention is shown generally at 10, mounted to a wall 12, and being used on the back 14 of a user 16 while the user 16 lies on a cushion mat 18 disposed on the floor 20. 
     The isometric push-up machine 10 includes a hollow &#34;L&#34;-shaped hollow tube 22, a larger outer upper hollow tube 24, a smaller inner lower hollow tube, a first outer rod 28, a second outer rod 30, an applicator 32, a spring compartment 34, a spring 36, a connector 38, a hinge 40, a pivot point 42, a steel cable 44, but is not limited to steel, a support bar 46, a first roller 48, a second roller 50, a mounting bracket 52, a handle 54, a lock pin 53 and a metal stopper 56. 
     In FIG. 2, the arrow 76 indicates the direction of which the user 16 is applying pressure. The arrow 76 also indicates the direction the user 16 is moving. 
     Since the spring 36 is seated in a metal stopper 56, disposed in the working portion 23, it biases the smaller inner lower hollow tube 26 in a downwardly direction. No energy is expended by the user 16 when the user 16 executes the movement in the direction of the arrow. 
     The resistance in the smaller inner lower hollow tube 26 is created by the springs 36A, 36B, or 36C, shown in FIG. 4. 
     As shown in FIG. 4A, the spring 36A or 36B or 36C is disposed in the spring compartment 34. Since, the springs 36A, 36B, and 36C, are independent of each other, by merely changing the spring 36 to a spring of different resistance a small variety of independent resistances can be utilized by the user 16, when pushing up in the direction of arrow 76. 
     FIG. 8 shows the details of the applicator 32. The applicator 32 includes a steel base 66, but is not limited to steel. The end foam pads 68 are larger than the center foam pad 70 so as to more better follow the curvature of the back 14 of the user 16. The smaller inner lower hollow tube 26 enters and attaches to the steel base 66. 
     A brief distance upward on the first smaller inner lower hollow tube 26, from the steel base 66, is disposed a pair of colinear handles used for doing curl arm exercises. 
     In order for the user 16 to enter and/or leave the isometric push-up machine 10, conveniently, the working portion 23 of the isometric push-up machine 10 swings inwardly, via the pivot point 42, when the handle 54 is pulled in its track. 
     When the handle 54 is pulled in the direction of arrow 81, the steel cable 44 being pivotally attached to the clamp 82, causes the working portion 23 to move in the direction of arrow 84 until the working portion 23 assumes the retracted position, shown in phantom. 
     The spring compartment 34 is disposed intermediate the non-working portion 25 and the larger outer upper hollow tube 24 and adds strength to the working portion 23. In order for the working portion 23 to retract in the direction of arrow 84, a hinge 40 allows the working portion 23 to pivot at point 42 in the direction of arrow 84 to the retracted position. 
     The first outer flat rod 28 and the second outer flat rod 30 are pivotably attached to the larger outer upper hollow tube 24 at the upper ends 94 and 96, while the lower ends 98 and 100 contain roller s 90 and 92 which ride in the first slot 58 and the second slot 60 of the smaller inner lower hollow tube 26 so that the smaller inner lower hollow tube 26 and the first outer flat rod 28 and the second outer flat rod 30 can move independently from each other. 
     The cable 44 originates at the clamp 82, passes around the first roller 48, and the second roller 50, and the non-working portion 25 underneath the base and up again on the handle 54. Once the user 16 is in place in the isometric push-up machine 10, the handle 54 is moved up to its original position which causes the cable 44 to slack and move in the direction of arrow 88 and allow the working portion 23 to return to its working position. 
     The non-working portion 25 is adjustably disposed in a wall bracket 52 which uses a lock pin 53 once the proper adjustment is obtained. 
     Referring now to FIGS. 5 through 7, the isometric push-up machine of the present invention is shown generally at 10&#39;, free standing on the floor 20&#39;, and being used on the back of a user while the user lies on a cushion mat 18&#39; disposed on the floor 20&#39;. 
     The isometric push-up machine 10&#39; includes a hollow &#34;L&#34;-shaped hollow tube 22&#39;, a larger outer upper hollow tube 24&#39;, a smaller inner lower hollow tube 26&#39;, containing a first slot 58&#39; and a second slot 60&#39;, a first outer rod 28&#39;, a second outer rod 30&#39;, an applicator 32&#39;, a spring compartment 34&#39;, a spring 36&#39;, a connector 38&#39;, a hinge 40&#39;, a pivot point 42&#39;, a steel cable 44&#39;, but is not limited to steel, a support bar 46&#39;, a first roller 48&#39;, a second roller 50&#39;, a pair of support bars 52&#39; and 53&#39;, a handle 54&#39;, a lock pin 53&#39; and a metal stopper 56&#39;. 
     The arrow 76&#39; indicates the direction of which the user is applying pressure. The arrow 78&#39; indicates the direction the user is moving. 
     Since the spring 36&#39; is seated in a metal stopper 56&#39;, disposed in the working portion 23&#39;, it biases the smaller inner lower hollow tube 26&#39; in a downwardly direction, no energy is expended by the user when the user executes the movement in the direction of arrow 78&#39;. 
     The resistance in the smaller inner lower hollow tube 26&#39; is created by the springs 36A&#39;, 36B&#39;, or 36C&#39;. 
     The spring 36A&#39; or 36B&#39; or 36C&#39; is disposed in the spring compartment 34&#39;. Since, the springs 36A&#39;, 36B&#39;, and 36C&#39;, are independent of each other, by merely changing the spring 36&#39; to a spring of different resistance a small variety of independent resistances can be utilized by the user, when pushing up in the direction of the arrow 76&#39;. 
     FIG. 8 shows the details of the applicator 32&#39;. The applicator 32&#39; includes a steel base 66&#39;, but is not limited to steel. The end foam pads 68 are larger than the center foam pad 70&#39; so as to more better follow the curvature of the back 14&#39; of the user. The smaller inner lower hollow tube 26&#39; enters and attaches to the steel base 66&#39;. 
     A brief distance upward on the first smaller inner lower hollow tube 26&#39;, from the steel base 66&#39;, is disposed a pair of colinear handles used for doing curling arm exercises. 
     In order for the user to enter and/or leave the isometric push-up machine 10&#39;, conveniently, the working portion 23&#39; of the isometric push-up machine 10&#39; swings inwardly via the pivot point 42&#39;, when the handle 54&#39; in its track is pulled. 
     When the handle 54&#39; is pulled in the direction of arrow 81&#39;, the steel cable 44&#39; being pivotally attached to the clamp 82&#39;, causes the working portion 23&#39; to move in the direction of arrow 84&#39; until the working portion 23&#39; assumes the retracted position, shown in phantom. 
     The spring compartment 34&#39; is disposed intermediate the non-working portion 25&#39; and the larger outer upper hollow tube 24&#39; and adds strength to the working portion 23&#39;. In order for the working portion 23&#39; to retract in the direction of arrow 84&#39;, a hinge 40&#39; allows the working portion 23&#39; to pivot at point 42&#39; in the direction of arrow 84&#39; to the retracted position. 
     The first outer flat rod 28&#39; and the second outer flat rod 30&#39; are pivotably attached to the larger outer upper hollow tube 24&#39; at the upper ends 94 and 96, while the lower ends 98&#39; and 100&#39; contain rollers 90&#39; and 92&#39; which ride in the first slot 58&#39; and the second slot 60&#39; of the smaller inner lower hollow tube 26&#39; so that the smaller inner lower hollow tube 26&#39; and the first outer flat rod 28&#39; and the second outer flat rod 30&#39; can move independently of each other. 
     The cable 44&#39; originates at the clamp 82&#39;, passes around the first roller 48&#39; and the second roller 50&#39; sown the non-working portion 25&#39; underneath the base and up again on the handle 54&#39;. Once the user is in place in the isometric push-up machine 10&#39;, the handle 54&#39; is moved up to its original position which causes the cable 44&#39; to slack and move in the direction of arrow 88&#39; and allows the working portion 23&#39; to return to its working position. 
     The non-working portion 25&#39; is adjustably disposed in a wall bracket 52&#39; which uses a lock pin 53&#39; once the proper adjustment is obtained. 
     It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of constructions differing from the type described above. 
     While the invention has been illustrated and described as embodied in an isometric push-up machine, it is not intended to be limited to the details shown, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention. 
     Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
