Waist twisting exercise machine

Abstract

A waist twisting exercise machine includes a substantially rectangular frame, an arm press on the left side and the right side of the frame that is movable up and down, and a leg press on a lower portion of the left side and the right side of the frame that is movable up and down. The arm press and leg press are fastened respectively to a pulley through a draw cable. The draw cable has one end fastened to a ring which can be coupled with user's arms and legs. When a user twists the upper portion of the body, the two arms can pull the draw cable to lift the arm press, thereby to exercise and enhance the strength of the waist, back muscles and arm muscles, and also improve instant burst strength and reaction.

1 . A waist twisting exercise machine, comprising: 
 a frame which is formed substantially rectangular and has respectively two vertical tubes on a left side and a right side thereof;    an arm press which is located respectively on the left side and the right side of the frame and movable up and down; the arm press having a plurality of weights, each of the weights having two apertures to be run through by the vertical tubes and a opening in a middle portion thereof to be coupled by a draw bar, the draw bar having a plurality of holes formed longitudinally thereon, one of holes being inserted by a rod which also runs through a notch formed on an outer side of the weight; the draw bar being fastened to at least one pulley through a draw cable, the draw cable having one end fastened to a ring, the ring being coupled with a user's arm;    wherein the user twists the upper portion of user's body, user's two arms pulling the draw cable to lift the weights.    
   
   
       2 . The waist twisting exercise machine of  claim 1  further including a leg press which has a plurality of weights, each of the weights having two apertures to be run through by the vertical tubes and a opening in a middle portion thereof to be coupled by a draw bar, the draw bar having a plurality of holes formed longitudinally thereon, one of the holes being inserted by a rod which also runs through a notch formed on an outer side of the weight; the draw bar being fastened to a pulley through a draw cable, the draw cable having one end fastened to a ring, the ring being coupled with an upper portion of a user's thigh.  
   
   
       3 . The waist twisting exercise machine of  claim 1 , wherein the ring includes a plurality of metal chain rings and is covered by a layer of elastic pliable pad.  
   
   
       4 . The waist twisting exercise machine of  claim 1 , wherein the frame has a pliable board on the bottom that is formed at a width same as the frame.  
   
   
       5 . The waist twisting exercise machine of  claim 1 , wherein the vertical tubes run through respectively two elastic elements on an upper side and a lower side that are located respectively on a transverse bar located on the two vertical tubes and the bottom of two sides of the frame to provide elastic cushion for dropping of the weights of the arm press and the leg press.
