Push up trainer

Abstract

An apparatus for performing pushups thereupon, comprising: two arcuate side pieces each comprising a gradually sloping front section and a sharply descending back section terminating in feet; each back leg being telescopically extendible from a back section of an arcuate side piece, and incorporating a locking means to keep the back legs extended by a desired amount; the front and back feet for supporting the apparatus on the ground; the apparatus further comprising a rectangle of struts coupling the arcuate legs together, and an upper cross bar for coupling the arcuate side pieces together near the highest point thereof; such that a user may alternatively: (i) grip the gently sloping front sections and ergonomically support his arms thereby to perform moderate press ups, or (ii) support his ankles on the upper cross bar and hands on the ground to perform demanding press ups.

1 . An apparatus supported on a substrated configured for performing pushups thereupon, the apparatus comprising:
 a framework comprising two arcuate side pieces each comprising a front section, having a gradual slope and a sharply descending back section, said two arcuate side pieces configured to facilitate a palm-facing grip for a user grasping said two arcuate side pieces to perform a pushup; the front section of the arcuate side piece terminating in a front foot and a back section terminating in an extendable leg section with a back foot thereupon; each of said back legs being telescopically extendible from a back section of an arcuate side piece, and incorporating a locking means to keep the back legs extended by a desired amount thereby adjusting said slope and said palm-facing grid of said user, said front and back feet being arranged for supporting the apparatus on the substrate.   
   
   
       2 . The apparatus of  claim 1  further comprising a rectangle of struts coupling the arcuate side pieces together, including a front strut for spanning between the two front sections of the arcuate side pieces at substrate level, a back strut for spanning between the two back sections of the arcuate side pieces above where extendible part extends out thereof, and a pair of side struts that span between the front section and the back section of each side piece to provide rigidity thereby; and, an upper cross bar for coupling the arcuate side pieces together near a highest point from the substrate; 
   
   
       3 . The apparatus of  claim 2  wherein said back sections are substantially straight telescopic tubes comprising piston like inner extension pieces that are useable to extend the back legs and to adjust the height of the upper cross bar from the ground and thereby adjust the slope of the angle of the gently sloping front section of the side pieces, such that said user may alternatively:
 (i) grip the gently sloping front sections and ergonomically support his arms thereby to perform moderate press ups, and   (ii) support the user's ankles on the upper cross bar and the user's hands on the substrate to perform demanding pushups.   
   
   
       4 . The apparatus of  claim 1  wherein said framework comprises tubing. 
   
   
       5 . The apparatus of  claim 1 , wherein said apparatus is fabricated from a material selected from a group consisting of aluminum, steel and plastic. 
   
   
       6 . The apparatus of  claim 2 , wherein said piston like inner tube is telescopically extendible from the cylindrical back leg and lockable in position by a peg. 
   
   
       7 . The apparatus of  claim 4 , wherein the peg is spring loaded for springingly engaging holes in the cylindrical outer tube of the back legs. 
   
   
       8 . The apparatus of  claim 1 , wherein said gradually sloping front sections of said arcuate said pieces are provided with hand grips. 
   
   
       9 . The apparatus of  claim 8 , wherein each said hand grip is an extensive tubular foam sleeve covering a length of the gradually sloping front section. 
   
   
       10 . The apparatus of  claim 9 , wherein said handgrips are arranged at an angle of from 20° to 60° to the substrate. 
   
   
       11 . The apparatus of  claim 1 , wherein said arcuate side pieces are separated by a distance of between 60 cm and 80 cm. 
   
   
       12 . The apparatus of  claim 1  wherein said feet comprise rubber grips to prevent the apparatus from slipping backwards. 
   
   
       13 . The apparatus of  claim 1  wherein a plurality of said apparatuses are stackable to be stored in a small space.
