Abdominal exercise device
First Claim
1. Device for performing abdominal lift exercises comprising:
- a flexible body belt adapted to be fastened adjustably and removably about an exerciser'"'"'s waist, said body belt having a centrally disposed opening, said opening facing and corresponding in size and position to the exerciser'"'"'s abdomen;
an expandable pocket mounted on said body belt, said pocket being affixed to the periphery of and surrounding said belt opening, sadi pocket being in the form of a bellows capable of being expanded outwardly and having an opening toward, facing sand corresponding in size and position to said belt opening and the exerciser'"'"'s abdomen;
an air-tight infaltable bag attached to the lower edge of said pocket, said bag being contained completely within said pocket when not inflated, said bag being shaped to protrude through said pocket opening and to press inwardly and upwardly directly against the exerciser'"'"'s abdomen through said belt opening and said pocket opening when inflated;
adjustable control means for regulating the magnitude of air pressure directed against the exerciser'"'"'s abdomen, said adjustable control means being mounted on said body belt and being characterized by the ability to limit and control selectivelythe expansion of said pocket and said bag outwardly from said body belt, thus directing more of less of said air pressure against the abdomen;
a bellows-type air pump adjustably suspended from said body belt, said air pump being adapted to rest against the exerciser'"'"'s thighs and to be operated by hand pressure thereagainst; and
flexible conduit means connecting said air pump and said inflatable bag for transmitting air therebetween.

Abstract
A device for exercising abdominal muscles by intermittent stretching and relaxing, and for massaging internal organs in the abdominal and thoracic cavities functions by applying adjustable intermittent pressure inwardly and upwardly to the surface of an exerciser'"'"'s abdomen. The exercise device comprises a body belt fastened around a user'"'"'s waist and having an opening covered with an expandable inwardly-facing pocket positioned over the user'"'"'s abdomen. An inflatable air-tight bag located within and attached to the pocket is connected to a hand-operated bellows-air pump, the pump being suspended from the body belt and resting on the user'"'"'s thighs when in use. At rest, the air-tight bag is collapsed and lies flat within the pocket; hand pressure against the bellows-air pump forces air up into and inflates the bag so that it protrudes through the pocket opening and exerts pressure inwardly and upwardly against the abdomen and forces the abdominal muscles to be stretched into the abdominal cavity. As the bellows pump is released, air is withdrawn from the collapsing air-tight bag and the abdominal muscles are relaxed until the exercise cycle is repeated. Adjustably overlapping flaps are provided on the belt to be closed over the pocket, thus limiting the outward thrust of the inflatable bag and selectively controlling the force exerted against the user'"'"'s abdomen.
