ABSTRACT:
An exercise block comprises a unitary body fabricated from compressible material that returns to its original shape after being compressed. The unitary body has front and rear end walls, opposite side walls, and top and bottom walls. Pairs of spaced apart flexible hand straps are attached to some of the walls for manipulating the block during a wide variety of exercise routines. An inner core also fabricated from compressible material that returns to its original shaped after being compressed is removably associated with the unitary body. Both the unitary body and the inner core each have a particular density whereby the overall compressibility of the exercise block is changeable depending upon the particular density of the inner core, and a plurality of inner cores of varying densities are provided for that purpose.
