Patent ID: 7704199

Claim:
A device for exercising the muscles in one's body, said device comprising: a base comprising a first base portion and a base member supported by the first base portion so that at least a portion of the base member is positioned above the first base portion, the base being supportable by a support surface, the support surface defining a normal axis that is perpendicular to the support surface; a plurality of openings formed in the base, each opening configured so as to define a first axis disposed generally axially through at least a portion thereof; and two resilient members, each comprising a first end portion and defining a second axis disposed generally axially through at least a portion of the first end portion thereof; wherein: the openings are each configured to provide a removable support for the first end portion of the resilient members, each resilient member being supported so that the second axis of the first end portion of the resilient member is generally aligned with the first axis of the opening providing the removable support and so that the resilient member extends from the opening in a cantilevered disposition; each opening is configured so as to prevent the first end portion of the resilient member supported by the opening from rotating relative to the base about an axis that is generally perpendicular to the first axis of the opening; each resilient member is configured to produce a resistance force when a user exerts a force thereon so as to deflect at least a portion of the resilient member from the longitudinal axis of the relaxed position of the resilient member, effecting an exercising of one or more muscles in the user's body; at least one of the plurality of the openings is formed in the base member and is oriented at a first angular orientation such that the first axis thereof is non-parallel to the normal axis; at least one of the plurality of the openings is formed in the base at a second angular orientation that is different than the first angular orientation; the base member defines an angled surface and at least one opening perpendicular to the angled surface configured to support at least one resilient member at the first angular orientation; and the device is configured such that the angular orientation of the centerline of at least a portion of each resilient member is adjustable from the first angular orientation to at least the second angular orientation without deflecting the resilient member from the longitudinal axis of the relaxed position of the resilient member by varying the opening defining the removable support of the resilient member.
