ABSTRACT:
An exercise device is disclosed that properly optimizes body mechanics to create a safe and effective lower body or combination upper body and lower body workout. The invention is comprised of a pad for the user to lay on and a foot plate to press the user's feet against. A lift arm is provided with handles at the user's sides. As the foot plate is pressed away from the body and the lift arm is pulled from the user's sides upward toward the head. A linkage connected to the arm supporting the foot plate and a linkage connected to the lift arm both work to rotate a center frame, which supports the pad thus doing work by vertically displacing the same and therefore the body weight of the user. Additional resistance can be added by an elastic spring which is situated to apply tension to oppose the rotational movement of the center frame relative to the base frame of the invention. Minimal resistance can be applied thereby creating an aerobic activity or increased greatly to provide an anaerobic, muscle building activity, each with minimal stress placed on the lower back of the user.
