A multi-functional, portable, lap-based exercise device comprising:
- (a) a first pair of spaced-apart, elongate parallel members defining a substantially uniformly, linear trough which has a proximal-to-the-user torso first longitudinal end and a distal second longitudinal end;
- (b) a linear channel disposed lengthwise of the inner surface of each of the opposing first pair and both serving to provide a dual channel track;
- (c) a first rigid cross strut which straddles the linear trough and being located variably therein between the parallel members of the first pair;
- (d) a lower first transverse member secured centrally thereof to the inner longitudinal ends of the parallel members and which first transverse member has opposing arcuate intermediate segments that extend upwardly, which segments are substantially parallel, and with the upper longitudinal ends thereof arrayed for straddling the chest of the device user;
- (e) an upper second transverse member secured at the longitudinal ends thereof to the upper longitudinal ends of the first transverse member;
- (f) a single rigid spanning bar connected pivotally at the upper longitudinal end thereof to about the midpoint of the upper second member with said bar being anchored functionally at the lower longitudinal end thereof to the first cross strut;
- (g) a third transverse cross member secured transversely of the distal second longitudinal ends of the first pair of parallel members, and adapted to provide a manually grippable means, serving to activate the exercise device;
- (h) a track-follower assembly pivotally attached to the first strut, and being secured centrally thereof, which assembly operatively traverses the dual channel of said first pair of members, as driven by the second transverse member;
- and,
- (i) a variably connectable, axially-movable, resilient tensioning band with the distal band segment thereof, being anchored at one longitudinal end to the track follower assembly and with the proximal band segment being anchored at its other longitudinal end to a point intermediate of undersurface of said linear channel of the first pair;
- and, whereby upon drawing inwardly the second transverse member along an inherent arcuate range of motion towards the third transverse member in the second member thereby moves the track follower assembly somewhat distally against the counter bailing tension imposed thereon by the tensioning band, and upon user release of the second member, such conversely permits the track follower assembly to return to its at rest position.
