ABSTRACT:
An abdominal muscle exerciser includes a seat and a lever arm which is rotatable in directions toward and away from the seat. The seat and lever arm are attached to a base. A pneumatic cylinder is biased between the base and the lever arm. The cylinder has a resistance stroke which provides significant resistance against rotation of the lever arm in the direction toward the seat. A cross bar is mounted transverse to the lever arm and a pair of foot stirrups are rotatably mounted on the cross bar.
