Abstract: An exercise assembly for assisting a user in performing squats and other exercise maneuvers is presented herein. The exercise assembly includes a substantially planar base platform, at least one riser bracket fixed to a top surface of the base platform, and a plurality of risers each selectively and removably disposable in a vertically stacked orientation within a channel of the at least one riser bracket to define a height-adjustable support block. Selective removal of one or more of the risers from the vertically stacked orientation within the channel will serve to lower the height-adjustable support block for the performance of more challenging squat exercises.
