CROSS-REFERENCES TO RELATED APPLICATIONS [0001]This patent application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/814,996 filed Jun. 20, 2006 for Ab Spinner Abdominal Exerciser, which application is incorporated here by this reference. TECHNICAL FIELD [0002]This invention relates to devices for aiding exercise of the abdominal muscles of a user. BACKGROUND ART [0003]In today's fitness conscious society, people are often interested in exercising their abdominal muscles. Currently, there are many ways this can be performed, some requiring equipment and some requiring the resistance of the exerciser's own body. Popular abdominal exercises include the sit-up, the crunch, reverse crunch, stability ball pull-ins, and the bicycle abdominal exercise. However, such exercises are often difficult to do with proper form. Additionally, these exercises are generally performed on the floor or by using complex gym equipment. As such the exercises can be uncomfortable or inconvenient for some persons. Furthermore, many existing devices for the abdominal muscles focus on a single primary exercise, such as the crunch. [0004]Therefore, there exists a need for an exercise device upon which a person can perform multiple abdominal exercises and to further ensure the exercises are done with the proper form. There exists a further need for an exercise device to allow the user to perform abdominal exercises off of the floor, in a comfortable position, and without the need for complex gym equipment. DISCLOSURE OF INVENTION [0005]The invention is directed to an exercise device having a seat, a spine, a hoop, a connector, and preferably at least one flexible rod. The spine extends upward from the rear edge of the seat, and the length of the spine may be adjustable. The hoop is connected to the spine by way of a connector, such as a dual-axis joint, at a circumferential portion of the hoop. The connector permits the hoop to rotate or pivot relative to the spine. The flexible rod extends outward from the hoop proximate the connector and is attached to a tensioning mechanism via a resistance cable at a second end of the flexible rod. The tensioning mechanism provides a tensile force in the resistance cable, permitting the flexible rod to provide a force to oppose the pivoting of the hoop. [0006]By sitting on the seat, enclosed by the hoop, and grasping the hoop with both hands, a person may perform a number of exercises, including an oblique twist, an abdominal crunch, a radial abdominal crunch, and an infinity abdominal crunch. The exercise device helps to ensure proper form and may provide resistance to the person's motions in order to provide a more strenuous exercise of the person's abdominal muscles.
