Patent ID: 8137249

Claim:
A device for exercising the muscles in one's body, said device comprising: a first base portion and a second base portion supported by a support surface, the support surface defining a normal axis that is perpendicular to the support surface; a first set of connection interfaces supported by the first base portion comprising a first connection interface having a first axial centerline and positioned at a first angular orientation and a second connection interface having a second axial centerline and positioned at a second angular orientation that is different than the first angular orientation; a second set of connection interfaces supported by the second base portion comprising a third connection interface having a third axial centerline and positioned at a third angular orientation and a fourth connection interface having a fourth axial centerline and positioned at a fourth angular orientation that is different than the third angular orientation; and at least one independently deflectable resilient member configured to produce a resistance force when a user exerts a force thereon so as to deflect at least a portion of each resilient member from the longitudinal axis of the relaxed position of each resilient member; wherein: each connection interface is configured to provide a removable support for each resilient member so as to support each resilient member in a cantilever disposition; the first axial centerline and the second axial centerline define a first plane; the third axial centerline and the fourth axial centerline define a second plane; and the first plane is not coplanar with the second plane.
