PUSH UP APPARATUS AND METHODS

摘要

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 three-dimensionally 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 three-dimensionally 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.
