Exercise device and methods of using the exercise device

A system of exercise devices, comprising:

• a plurality of exercise devices, each exercise device of the plurality of exercise devices including:
• a top face;
• and
• an open framework body permanently connected to said top face, said open framework body formed as a plurality of bar-shaped hand grips defining a plurality of planar faces, such that:
• a respective hand grip of said plurality of hand grips is formed at each intersection between two contiguous faces of said plurality of faces;
• said plurality of faces include at least two faces, each of said at least two faces extending from a different side of said top face, and each of said at least two faces being substantially perpendicular to said top face;
• said plurality of faces further includes a bottom face substantially parallel to said top face;
• each respective face of said at least two faces is defined by a different edge of said top face, and by hand grips of said plurality of hand grips formed at each intersection between the respective face and each contiguous neighboring face of said plurality of faces;
• and
• each face of said plurality of faces being open between said plurality of hand grips, with at least one face of said plurality of faces being completely open between respective hand grips of said plurality of hand grips;
• and
• the exercise device configured as a right rectangular prism with each of said at least two faces of said plurality of faces extending between said top face and said bottom face, intersections of each of said at least two faces with said bottom face forming a hand grip at an edge of said bottom face, said bottom face configured to rest directly on a support surface;
• at least a portion of said top face being a solid, closed surface permanently connected between two opposite faces of said at least two faces of said open framework body;
• and
• each exercise device of said plurality of exercise devices having the same physical dimensions as the other exercise devices of said plurality of exercise devices and being a different weight from the other exercise devices of said plurality of exercise devices.
