ABSTRACT:
An abdominal exercise machine is provided which includes a seat, which is pivotally linked to a base frame. At least one link includes a handle that can be actuated by a user sitting on the seat. The user presses the handle away from the seat by flexing the trunk muscles of the user. This curls the user's body into a flexed trunk position. As the handle is actuated forward, the linkage arrangement causes the seat to displace upward. This pushes the center of gravity of the user up, thereby doing work and thereby providing resistance to the movement caused by the exercise. The handle may be adjustable in position relative to the link, thereby varying the load used by the user. Foot supports may also be provided either in front of the seat or behind the seat. The foot supports may be mounted to the frame of the seat frame which supports the seat.
