Exercise discs

Abstract

A pair of exercise discs which will allow the wearer to engage in cardiovascular type exercises. The discs have a smooth, slippery surface on the bottom and a rough, textured surface on the top. In addition, the bottom has a pair of “wings” to prevent sidewise drifting of the discs.

What is claimed as my invention is:  
     
         1 . An exercise device adapted to be worn on a user's feet, said exercise device comprising: 
 a platform made from a compressible material which compresses when a user stands on said platform, and    said platform having a top surface, a bottom surface, a front, back and sides,    said top surface being relatively flat and having a roughened texture,    said bottom surface being relatively flat and having a texture that is more slippery than said top surface,    said exercise device adapted to be placed on a user's feet,    said exercise device being secured solely by said roughen ed texture on said top surface, and    wherein said bottom surface has at least two projections depending downwardly from said bottom surface,    said at least two projections being unitary with said bottom surface, and    said at least two projections being positioned only on opposite sides of said bottom surface, and    said bottom surface that is more slippery than said top surface extending only across a width of said bottom surface between said at least two projections.    
     
     
         2 . The exercise device as claimed in    claim 1   , wherein said front of said platform is curved upwardly from said bottom surface toward said top surface.  
     
     
         3 . The exercise device as claimed in    claim 1   , wherein said back of said platform is curved upwardly from said bottom surface toward said top surface.  
     
     
         4 . The exercise device as claimed in    claim 1   , wherein said roughened texture on said top surface is a paint having sand dispersed therein.  
     
     
         5 . The exercise device as claimed in    claim 1   , wherein said roughened texture on said top surface is a knurled surface.  
     
     
         6 . The exercise device as claimed in    claim 1   , wherein said roughened texture on said top surface is a plurality of score lines placed along said top surface.  
     
     
         7 . The exercise device as claimed in    claim 1   , wherein said bottom surface has at least one projection depending downwardly from said bottom surface.  
     
     
         8 . The exercise device as claimed in    claim 1   , wherein said slippery texture on said bottom surface is a coating having a low coefficient of friction.  
     
     
         9 . The exercise device as claimed in    claim 8   , wherein said coating is Teflon.  
     
     
         10 . The exercise device as claimed in    claim 1   , wherein said exercise device comprises two platforms, 
 one of said two platforms being used on one of a user's feet, and    another of said two platforms being used on another of said user's feet.
