Claim:
An abdominal exercise machine comprising: a frame supporting a seat forming a first plane; at least one support bar extending from a first end to a second end and mounted to the frame through a first pivot axis extending transversely through the first end of the at least one support bar; a head support forming a second plane pivotally supported at the second end of the at least one support bar through a second pivot axis extending substantially parallel to the first pivot axis; a back support supported by at least one of the head support and the at least one support bar proximate to the second pivot axis; a third pivot axis formed between the back support and the head support and extending substantially perpendicular to the first pivot axis and the second pivot axis to allow the head support to rotate transversely to the first pivot axis and the second pivot axis; and wherein the back support is moveable with the at least one support bar and the head support relative to the frame and the seat to support a lower back of an individual seated on the seat through a range of motion undertaken by the individual during an abdominal exercise process causing rotation about the first pivot axis, the second pivot axis, and the third pivot axis.
