Patent ID: 8162809

Claim:
An exercise device, which comprises: a) a flexible base member that is removably positionable between a seat and body of a user, said base member having opposed surfaces and being symmetrically configured about a generally central axis, and having opposed tapered sides such that one end is greater in dimension than the other, the longer side having generally arcuate corners and the shorter side having generally obtuse corners, said base member having surface dimensions sufficient to extend at least substantially over the entire buttock area of the user, whereby during use, the configuration and dimension of the base member provides substantially full immovable contact with substantially the entire buttock area of the user on one surface and with the seat on the other surface without need for fasteners, said base member being made of a material which is foldable, yet of sufficient strength to withstand tensile and shear forces; b) a plurality of apertures located inwardly of respective peripheral edges of said base member to facilitate attachment of resilient resistance members for exercise purposes; and c) at least one resilient resistance member being attachable to said base member through a select one or more of said apertures so as to extend generally outwardly from said base member, each said resistance member having an attachment end and a free end, each said resistance member having a gripping device attached to the free end thereof to facilitate exercise movements by the user, whereby a user may position said base member between a selected portion of the body of the user and the seat to provide firm and immovable contact therebetween and to thereby grip and extend selective ones of said resistance members against their natural resistance for exercise purposes, said flexible member further being capable of being folded, crumpled and rolled for portability and ease of storage.
