Abstract

An exercise apparatus is placed on a supporting surface where a linear support frame and a supporting strut depending from an elevated end of the linear support frame maintains the linear support frame at selected angles with respect to the supporting surface. A user support strut provides a seat, and is pivotally engaged with the linear support frame proximal its elevated end. A raising strut is pivotally engaged with the linear support frame at their lower ends. An intermediate strut is fixed between the user support strut and the raising strut, such that when the raising strut is pivoted upwardly, the seat strut is caused to pivotally move upwardly as well. Cables are mounted so that the user is able to apply force to the raising strut to lift the users own weight in a pivoting action during exercising.

1 . An exercise apparatus on a supporting surface, the apparatus comprising: a linear support frame oriented at a selected angle to the supporting surface and thereby defining an elevated end of the linear support frame; a supporting strut depending from the elevated end of the linear support frame for resting on the supporting surface in maintaining the linear support frame at the selected angle; a user support strut having a user support, the support strut pivotally engaged with the linear support frame proximal the elevated end thereof; a raising strut pivotally engaged with the linear support frame at a lower end thereof; and an intermediate strut engaged between the user support strut and the raising strut, such that when the raising strut is pivoted upwardly, the user support strut is caused to pivotally move upwardly therewith for raising a user's weight.  
   
   
       2 . The apparatus of  claim 1  further comprising: a raising pulley engaged at a free end of the raising strut; and, engaged with the linear support frame, an idler pulley, a pair of intermediate directing pulleys, and a pair of upper terminal pulleys.  
   
   
       3 . The apparatus of  claim 2  further comprising an arm exercise cable medially routed around the raising pulley and thence to the intermediate directing pulleys and the upper terminal pulleys, and terminating at opposing ends thereof, each with a hand grip positioned proximal the user support.  
   
   
       4 . The apparatus of  claim 1  further comprising: a raising pulley engaged at a free end of the raising strut; a lower terminal pulley engaged at a free end of the user support strut, and engaged with the linear support frame, an idler pulley, an intermediate directing pulley, and a cable termination.  
   
   
       5 . The apparatus of  claim 4  further comprising a leg exercise cable medially routed around the raising pulley and thence, at one end thereof, to the idler pulley, the lower terminal pulley and terminating at a hand grip proximal the user support; and at an opposing end of the leg exercise cable, to one of the intermediate directing pulleys and terminating at the elevated end of the linear support frame at the cable termination.  
   
   
       6 . The apparatus of  claim 1  wherein the raising strut and the user support strut are enabled for folding in line with the linear support frame.  
   
   
       7 . An exercise apparatus on a supporting surface, the apparatus comprising: a support frame having an elevated end; a supporting strut depending from the support frame for resting on the supporting surface in maintaining the support frame at selected angles relative to the supporting surface; a user support strut having a user support, the user support strut pivotally engaged with the support frame proximal the elevated end thereof; a raising strut pivotally engaged with the support frame at a lower end thereof; and pivotally engaged with the user support strut, such that when the raising strut is pivoted upwardly, the user support strut is caused to pivotally move upwardly therewith for raising a user's weight resting on the user support.  
   
   
       8 . The apparatus of  claim 7  further comprising: an exercise cable engaged with the raising strut in such manner that pulling on the exercise cable raises the user support strut pivotally.  
   
   
       9 . The apparatus of  claim 7  wherein the raising strut and the user support strut are enabled for folding in line with the support frame.  
   
   
       10 . The apparatus of  claim 8  wherein the support frame is telescopingly extendable for positioning the exercise cable at a selected angle relative to the user support.
