Upper Body Exercise Machine

Abstract

The present invention relates to an upper body exercise machine. The exercise machine enables users to work out multiple upper body muscle groups simultaneously by a simple exercise movement. The machine includes a rotatable arm that is rotated using a handle secured to the arm. The arm is rotated using an axle (i.e. rotated around an axle) that is connected to a resistance wheel. By turning a resistance knob, resistance to the rotation of the arm can be adjusted, and a user can apply force based on the selected resistance. The arm can include a plurality of handle-mounting holes for receiving the handle to change the amount of leverage, or moment arm, applied for rotating the arm.

         5 . The exercise machine of  claim 4 , wherein said first moment arm is greater than said second moment arm. 
     
     
         6 . The exercise machine of  claim 5 , wherein said second moment arm is greater than said third moment arm. 
     
     
         7 . The exercise machine of  claim 6 , wherein said height adjusting holes are in fixed positions along said length of said pedestal. 
     
     
         8 . An exercise machine with a rotatable arm for strengthening the upper body of a user, the exercise machine comprising:
 a rotatable arm connected to a rotating wheel through an axle, wherein said rotating wheel mounted to a vertical pedestal;   said vertical pedestal including a plurality of height adjusting holes for positioning said rotating wheel at a desired height relative to said user, wherein said plurality of height adjusting holes spaced along the length of said vertical pedestal;   said rotating wheel includes a plurality of bearings for supporting rotation of said rotatable arm;   said rotatable arm having a plurality of handle mounting holes to receive a handle, wherein said handle when secured to one of said plurality of handle mounting holes is held by said user for rotating said rotatable arm in a clockwise or a counterclockwise direction to target a majority of the muscles of the upper body; and   said plurality of handle mounting holes includes at least a first handle mounting hole and a second handle mounting hole, wherein said first handle mounting hole includes a first moment arm relative to said axle and said second handle mounting hole includes a second moment arm relative to said axle.   
     
     
         9 . The exercise machine of  claim 8  further comprising a resistance knob configured to be turned to adjust resistance of said rotating wheel to the rotation of the rotatable arm. 
     
     
         10 . The exercise machine of  claim 8 , wherein said bearings are thrust bearings. 
     
     
         11 . The exercise machine of  claim 8  further comprising a third handle mounting hole, wherein said third handle mounting hole includes a third moment arm relative to said axle. 
     
     
         12 . The exercise machine of  claim 8 , wherein said first moment arm is greater than said second moment arm. 
     
     
         13 . The exercise machine of  claim 11 , wherein said second moment arm is greater than said third moment arm. 
     
     
         14 . The exercise machine of  claim 8 , wherein said height adjusting holes are in fixed positions along said length of said pedestal. 
     
     
         15 . A method for strengthening an upper body of a user, the method comprising the steps of:
 connecting a rotatable arm to a rotating wheel through an axle, wherein said rotatable arm having a plurality of handle mounting holes to receive a handle;   said plurality of handle mounting holes includes at least a first handle mounting hole and a second handle mounting hole, wherein said first handle mounting hole includes a first moment arm relative to said axle and said second handle mounting hole includes a second moment arm relative to said axle;   vertically adjusting a height of said rotating wheel on a vertical pedestal, wherein said vertical pedestal including a plurality of height adjusting holes for positioning said rotating wheel at a desired height relative to said user;   mounting said handle to one of said plurality of handle mounting holes;   holding said handle by said user; and   rotating said rotatable arm in a clockwise or a counterclockwise direction to target a majority of the muscles of the upper body.   
     
     
         16 . The method of claim of  claim 15  further comprising a step of adjusting a resistance knob configured to be turned to adjust resistance of said rotating wheel to the rotation of the rotatable arm.
