Claim Text:
1. An exercise device comprising: a flexible base member having a first surface and a second surface, and a plurality of periphery edges, the flexible base member configured for placement between a seating surface of a seat and a buttock area of a user, and dimensioned to extend at least substantially over the entire buttock area of the user, the flexible base member including one or more reinforced apertures as attachment points proximate to and located inwardly of at least two of the periphery edges of the flexible base member, wherein the flexible base member is capable of being folded, crumpled and rolled for portability and ease and flexibility of storage; and at least one resilient resistance member having two opposing ends, a handle end and an attachment end, the attachment end removably attached to the base member only at one of the one or more attachment points at the periphery edges, whereby during use, the configuration and dimension of the flexible base member provides substantially full immovable contact with substantially the entire buttock area of the user on the first surface and with the seat on the second surface without need for fasteners, and to thereby grip at the handle end and extend the at least one resistance member against its natural resistance by virtue of the connection of the attachment end of said at least one resistance member and the attachment point.
