The exercise bar is attached near the wedge's apex and extends lengthwise parallel to the device at a predetermined distance from the wedge. The physical exercising device has its base formed from a lightweight material and additionally may have its body support surfaces covered with a layer of carpet or foam padding. The spring which has its one end attached to the exercise bar has its opposite end secured to the end panel of the wedge-shaped base to provide a biasing force.
