Plank exercise assistance apparatus

A system for a plank exercise assistance apparatus, comprising:

• a. a body having a frustoconical shape including a base, said base extending circumferentially about a bottom edge of the body, said base having a bottom surface, said body having a front side and a rear side;
• b. slidable coasters mounted under said bottom surface of said base, wherein the slidable coasters are hemispheres with a flat portion mounted to the bottom surface, said hemispheres being smooth to reduce friction when traveling across a surface;
• c. a receptacle in a center of said body, said receptacle including a cavity that extends from an interior edge of an open top portion to an interior central U-shaped portion with respect to the body, the interior central U-shaped portion adapted to receive both feet of a user;
• d. a front side opening of said front side adapted to be of a size larger than both feet of the user so as to allow said both feet of the user to pass through and be entirely housed within said receptacle with an exception of a heel of the user;
• e. a heel stopper extending vertically from said rear side adapted to prevent the heel of the user passing beyond said heel stopper, wherein said heel stopper creates a convex extension of a top edge of the rear side;
• and
• f. a leg support protruding laterally from the front side, wherein the leg support is located entirely between the heel stopper and the base, the leg support extending away from said base towards said user, said leg support adapted to cradle a shin of the user, said base extending further than the leg support.
