Abstract
An abdominal exercise device includes a first U-shaped frame member pivotally attached to a second U-shaped frame member. Each frame member includes a pair of spaced parallel legs and a cross section extending therebetween. A head rest is mounted on the cross section intermediate the legs of the first frame member. An adjustable pivot tube is telescopically mounted within each leg of the first frame member to adjust the length of the legs. The legs of the first and second frame members are pivotally attached to each other generally adjacent the free ends thereof. A pair of spaced flexible straps extend between the cross sections of the frame members. A spring-biased detent pin is mounted within the hollow interior of each of the legs of the first frame member and is selectively engaged in holes formed in the legs of the first frame member to provide linear adjustment to the first frame member. A user lies on a support surface between the frame members and the user's head is positioned on the head rest and the second frame member is grasped by the user. The free ends of the second frame member pivots on the support surface as the user performs a sit-up or an abdominal crunch. The device can be flipped upside-down and used to perform reverse crunches. The device is collapsible for compact and easy storage.
