An exercise machine includes a frame having a horizontally extending seat mounted thereon. A foot restraint assembly is pivotally mounted about a first horizontal pivot axis to the frame. A motion translation arrangement has one end pivotally secured about a second horizontal pivot axis to the frame, and an opposite end extending beyond the frame. An arm, back and head support is pivotally secured about a third horizontal pivot axis to the opposite end of the motion translation arrangement and is moveable forwardly relative to the foot restraint assembly. The second horizontal pivot axis and the third horizontal pivot axis enable a sequential, compound, articulated abdominal exercise movement as the arm, back and head support is moved towards the foot restraint assembly.
