The knee support may include a telescoping upright post, a knee support inner shaft, a knee radial pivot lock bracket, a knee cushion and an upper leg support rest.

What is claimed is: 
     
         1 . A stand-up abdominal/back muscle exercise device comprising:
 a base;   an ankle support attached to the base comprising;
 a t-bar having a vertical portion extending from the base and a horizontal portion; 
 a support shaft having a cross bar section extending from the horizontal portion of the t-bar; 
 an ankle padding connected to the cross bar section of the support shaft; 
   a knee support attached to the base comprising;
 a telescoping upright post having a top end, an interior housing and at least one vertical knee hole; 
 a knee support inner shaft having have at least one inner shaft hole within the internal housing of the telescoping upright post; 
 a pivot lock pin removably inserted into the at least one inner shaft hole of the knee support inner shaft and the at least one vertical knee hole of the telescoping upright post; 
 a knee radial pivot lock bracket having an outer side with at least one pivot lock hole, an inner side and a top edge, wherein the knee radial pivot lock bracket is attached to the top end of the telescoping upright post; 
 a pivot lock pin removably inserted in to the at least one pivot lock hole of the knee radial pivot lock bracket; 
 knee cushion padding extended out from the inner side of the knee radial pivot lock bracket; and 
 an upper leg support rest attached to the top edge of the knee radial pivot lock. 
   
     
     
         2 . The stand-up abdominal/back muscle exercise device of  claim 1 , further comprising a steady post positioned in front of the ankle support and attached to the base. 
     
     
         3 . The stand-up abdominal/back muscle exercise device of  claim 1 , wherein the ankle support and the knee support attach to the base by an upright collar. 
     
     
         4 . The stand-up abdominal/back muscle exercise device of  claim 1 , wherein the ankle padding and the knee cushion padding are made of vinyl. 
     
     
         5 . The stand-up abdominal/back muscle exercise device of  claim 1 , wherein the upper leg support rest attaches to the top edge of the knee radial pivot lock by at least one “L” bracket rail. 
     
     
         6 . A method for exercising abdominal and back muscles using a stand-up abdominal/back muscle exercise device comprising the steps of;
 stepping onto a base of the stand-up abdominal/back muscle exercise device;   adjusting the vertical height of a knee support of the stand-up abdominal/back muscle exercise device, the knee support defined by a telescoping upright post, a knee support inner shaft, a knee radial pivot lock bracket, a knee cushion padding and an upper leg support rest;   adjusting the radial degree of the knee radial pivot lock bracket in order to present the upper leg support rest in the desired position;   adjusting the vertical height of an ankle support of the stand-up abdominal/back muscle exercise device, the ankle support defined by a t-bar, a telescoping inner horizontal support shaft, a telescoping inner vertical support shaft, and an ankle padding;   adjusting the horizontal height of the ankle support in order to present the ankle support in the desired position;   stepping in front of the knee support and behind the ankle support;   leaning backward and forward with upper legs supported by the upper leg support and ankles secured by the ankle support.
