ABSTRACT:
An exercise machine for exercising the total abdominal zone and muscles of an exercising person. The machine's chassis is comprised of base members and upwardly extending members which support a downwardly arcuate seating member for the exercising person. Back support apparatus is provided which includes a frame rotatably attached to the rear end of the seating member, a back rest slidably affixed within the central area of the frame, a pair of handles extending from the top of the frame and weights which are movably affixed to the rear of the frame for adjusting the amount of lever force required to be applied by the exercising person to the handles to move the back support forwardly during exercise use of the machine. The machine also includes leg support apparatus consisting of an extensible tubing arrangement attached at its rearward end to the front end of the arcuate seating member, and pedals attached to the forward end of the tubing arrangement for receiving and supporting the feet of the exercising person.
The exercise machine is operable so that abdominal muscles are exercised by: (a) movement only of the arms and upper torso of the exercising person through levered rotation of the back support apparatus through pulling action of the arms (the leg support apparatus being maintained stationary); (b) movement only of the leg support apparatus through levered rotation of the leg support apparatus (the back support apparatus being maintained stationary); and (c) rotative movement together of the back support apparatus and the leg support apparatus.
