Push up apparatus and methods

Abstract

One or more aspects comprise an apparatus comprising: (a) a base component comprising a flat lower surface and a concave upper surface having a first curvature; and (b) a handle component comprising a convex lower surface having a second curvature; wherein the first curvature and the second curvature conform sufficiently to allow the handle component to rotate within the base component, and wherein at least one of the concave upper surface and the convex lower surface comprises means to allow the handle component to rotate within the base component. Other aspects and embodiments, including methods of use and manufacture, will be apparent to those skilled in the art after reviewing the description and drawings provided herein.

We claim: 
     
         1 . An apparatus comprising:
 a base component comprising a flat lower surface and a concave upper surface having a first curvature; and   a handle component comprising a convex lower surface having a second curvature;   wherein said first curvature and said second curvature conform sufficiently to allow said handle component to rotate within said base component, and   wherein at least one of said concave upper surface and said convex lower surface comprises means to allow said handle component to rotate within said base component.   
     
     
         2 . An apparatus as in  claim 1 , wherein said handle component has a concave upper surface. 
     
     
         3 . An apparatus as in  claim 2 , wherein said handle component comprises a handle that extends between opposite sides of said concave upper surface. 
     
     
         4 . An apparatus as in  claim 1 , wherein at least one of said concave upper surface and said convex lower surface comprises a plurality of conveyor ball transfer assemblies. 
     
     
         5 . An apparatus as in  claim 1 , wherein at least one of said concave upper surface and said convex lower surface comprises a non-stick coating. 
     
     
         6 . An apparatus as in  claim 1 , wherein at least one of said concave upper surface and said convex lower surface comprises one or more hook-and-loop fasteners. 
     
     
         7 . An apparatus as in  claim 4 , wherein each of said conveyor ball transfer assemblies comprises a single ball having a first diameter, which rides on a plurality of balls having a second diameter. 
     
     
         8 . An apparatus as in  claim 7 , wherein said single ball is a nylon ball. 
     
     
         9 . An apparatus as in  claim 7 , wherein said plurality of balls are steel balls. 
     
     
         10 . An apparatus as in  claim 1 , wherein said flat lower surface of said base component comprises a non-skid layer. 
     
     
         11 . An apparatus as in  claim 3 , wherein said handle is enclosed within a foam grip.
