ABSTRACT:
An exercise machine for isolating and strengthening the abdominal muscles has a horizontally-movable plunger having a convex-shaped back contacting pad for linearly applying the force of a weight stack to resist back flexing of a seated user, and also has arm and leg immobilizing structure to arrest reactionary forces during such flexing, thereby minimizing hip flexion. The plunger is attached to a carriage mounted for horizontal movement on rails. A cable connection between the carriage and the weight stack includes a cam for varying resistance with changes in the degree of flexing.
