Abstract:
A portable abdominal muscles and hip fitness exercise device adapted to be positioned during use on a conventional chair support, while being temporarily anchored thereto by the weight of a user seated upon the chair-seating component of the device, comprising:(a) a generally rectangular rigid frame having a first and a second transverse members, with the frame adapted to be positioned firmly upon planar element of a conventional chair support with the second member axially mounted so as to permit axial rotation; (b) a generally planar seating means sized to overlie the rectangular frame, being secured along its rearward edge to the rearward second transverse member, and secured along its forward edge to the forward first transverse member of the rigid frame; (c) a pair of spaced-apart, elongate handles anchored at the inner longitudinal ends thereof, conjoined to the longitudinal ends of the second transverse member of the rigid frame, forming rearward corners with such handles projecting forwardly at an angle relative to the rigid frame; (d) a third transverse member bridging the space between the paired elongate handles and being positioned therebetween, being spaced apart from and below the second transverse member, and being journal-mounted so as to permit the axial rotation thereof; (e) a single L-shaped, lever arm secured pivotally at the one proximal elongate segment thereof to one longitudinal end of the third member, with the lever arm having its distal longitudinal segment aligned both transversely and horizontally, and spaced apart substantially from and above the level of the associated underlying seating means; and, (f) a tensioning means positioned under the seating means and being anchored thereto, which tensioning means is operatively associated with the proximal elongate segment of the single transverse lever arm, with such tensioning means being adapted to provide a variable resistance to the upward motion of the transversely positioned distal segment of the lever arm, the arcuate motion of which is induced by a drawing in, thigh action of the device-seated user.
