1. A device to aid a user in exercising abdominal muscles comprising:
- An elongated rigid member being mechanically coupled to the user'"'"'s upper body whereby rotational movement of the upper body imparts rotational movement to the rigid member, wherein the rigid member comprises an arcuate portion designed and configured to accommodate a back portion of the user'"'"'s neck to facilitate stable positioning of contact between the user'"'"'s neck and the rigid member, andat least one extensible resistance member having a first end and second end,wherein the first end is attached to the rigid member and the second end is attachable to at least one location isolated from the movement of the user'"'"'s upper body,wherein rotational movement of the elongated rigid member causes chance in extension of the extensible resistance member and the extensible resistance member exerts a force on the rigid member opposing the change in extension,wherein the extensible resistance member is adjustable to vary at least one of the length of the extensible member and the degree of resistance to changes in extension exhibited by the extensible member, andwherein the moment of inertia exerted by the rigid member on the upper body of the user remains substantially constant as the resistance to changes in extension of the extensible resistance member is varied.

Abstract
An article for allowing a person to exercise the oblique abdominal muscles comprises a rigid member, in accordance with a preferred method of use, is grasped in the hands and held behind the neck. At either end of the rod, an elastic member extends downward with the distal end of each elastic member being held against the floor by the person'"'"'s foot. As the user swivels the upper body, the elastic members are placed in tension and provide resistance for exercising the oblique abdominal muscles.

14. A method for exercising abdominal muscles of a person comprising the steps of:
-
coupling an elongated rigid member to the upper body of the person wherein rotation of the upper body of the person relative to the lower body of the person causes rotation of the rigid member relative to the lower body of the person, and wherein the rigid member comprises an arcuate portion and wherein the coupling step further comprises placing the arcuate portion of the rigid member in contact with the back of the neck of a user, coupling a first end of at least one extensible resistance member to the rigid member, coupling a second end of the extensible resistance member to a location that is designed and configured to remain substantially fixed relative to the lower body of the person wherein rotational movement of the elongated rigid member causes change in extension of the extensible resistance member and the extensible resistance member exerts a force on the rigid member opposing the change in extension, and using the abdominal muscles of the person to force the rigid member to rotate relative to the lower body of the person and to cause the extensible resistance member to change in extension, wherein the extensible resistance member is adjustable to vary at least one of the length of the extensible member and the degree of resistance to changes in extension exhibited by the extensible member, and wherein the moment of inertia exerted by the rigid member on the upper body of the user remains substantially constant as the resistance to changes in extension of the extensible resistance member is varied.
