ABSTRACT:
A body extension exercise machine includes a frame, an elongated support connected to the frame and defining a reclined exercise position for an exerciser and a lever connected to the frame for pivotal movement about a pivot axis oriented transverse to and located below the support. A lower end of the lever includes a weight holder for holding a predetermined weight, and an upper end of lever includes a plate. When in the exercise position and reclined on the support, with at least one leg retracted and in contact with the plate, an exerciser pushes outwardly against the plate and against the held weight resistance to pivot the lever with respect to the frame from an initial at-rest position to a leg-extended position. Thereafter, the exerciser reduces the force applied to the plate and allows the lever to pivot back to the at-rest position, corresponding to the legs retracted position. This leg extension and leg retraction simulates a squat exercise, and it optimally exercises the quadriceps and hamstring muscles. In contrast to a squat, this exercise machine eliminates the well known safety hazards of a squat exercise performed with a barbell.
