ABSTRACT:
This invention directs itself to a portable exercising system (10) which includes a stabilization mechanism (24) for contact with a resistive force load applying mechanism which may be a user's feet (22) or a stationary rigid object such as a door (62). The stabilization mechanism (24) is coupled to a force load application mechanism (38) through an adjustable securement mechanism (46) which adjusts the displacement distance between the stabilization mechanism (24) and the force load application mechanism (38) in a transverse direction (30). The force load application mechanism (38) contiguously interfaces and contacts the front of the user's thighs (14) while the user's feet (22) are mounted to and hold the stabilization mechanism (24) against a base surface (18). In this manner, a wedge type force action is applied to the user and during particular exercises such as sit-up type exercises, the user isolates a particular muscle group such as the abdominal muscle group which enhances and maximizes the efficiency of a particular exercise.
