Twisting exerciser

Abstract

A twisting exerciser includes a base with a tubular extension and multiple first adjusting holes defined through a periphery of the tubular extension. A cushion has a cylindrical bottom received in the tubular extension and provided with multiple second adjusting holes defined to correspond to the first adjusting holes and multiple legs extending out therefrom. A pin extends into one of the first adjusting holes and one of the second adjusting holes to secure engagement and a relative position between the tubular extension and the cylindrical bottom. A stepping board is securely mounted on and supported by the cushion. The stepping board is able to be twisted and rocked so as to provide an exercising effect to a user.

What is claimed is:  
     
         1 . A twisting exerciser comprising: 
 a base with a tubular extension formed on a center of the base and having multiple first adjusting holes defined through a periphery of the tubular extension;    a cushion having a cylindrical bottom received in the tubular extension and provided with multiple second adjusting holes defined in an outer face of the cylindrical bottom to correspond to the first adjusting holes of the base and multiple legs formed on a top face of the cylindrical bottom and extending out therefrom, wherein the cylindrical bottom has a height larger than that of the tubular extension so that the legs extend out outside the tubular extension;    a pin extending into one of the first adjusting holes and one of the second adjusting holes to secure engagement and a relative position between the tubular extension and the cylindrical bottom; and    a stepping board securely mounted on and supported by the cushion,    whereby the stepping board is able to be twisted and rocked so as provide an exercising effect to a user.    
     
     
         2 . The twisting exerciser as claimed in  claim 1 , wherein the stepping board has a protrusion formed on a bottom face of the stepping board and the cushion has a recessed area defined in a top face of the cushion to receive therein the protrusion.  
     
     
         3 . The twisting exerciser as claimed in  claim 2 , wherein multiple cutouts are defined in a peripheral edge of the stepping board and a securing rod is securely mounted in a corresponding one of the cutouts.  
     
     
         4 . The twisting exerciser as claimed in  claim 1 , wherein the stepping board has multiple oppositely formed handles on a peripheral edge of the stepping board.  
     
     
         5 . The twisting exerciser as claimed in  claim 2 , wherein the stepping board has multiple oppositely formed handles on a peripheral edge of the stepping board.  
     
     
         6 . The twisting exerciser as claimed in  claim 3 , wherein the stepping board has multiple oppositely formed handles on the peripheral edge of the stepping board.  
     
     
         7 . The twisting exerciser as claimed in  claim 3  further comprising a pair of elastic elements oppositely and detachably connected to the securing rods on the stepping board.  
     
     
         8 . The twisting exerciser as claimed in  claim 6  further comprising a pair of elastic elements oppositely and detachably connected to the securing rods on the stepping board.
