ABSTRACT:
An exercise device for doing crunches that has a frame that includes a head rest support to support the back of the head, two wings extending outwardly from opposite sides of the head rest support and a torso support. The wings each accommodate stacking of weights. The head rest support and the torso support cooperate with each other to stabilize the relative position of the head and neck by preventing their relative movement with respect to the upper torso.
