1. An exercise apparatus comprising:

  • (a) a frame;

    (b) a carriage, suspended from the frame for oscillatory motion relative thereto; and

    (c) a motor, adapted to receive at least some of its required input energy in the form of human motion, connected to the frame and the carriage so as to urge the carriage to move relative to the frame, wherein the motor includes;

    (i) an input transducer for receiving energy in the form of human motion;

    (ii) an actuator having a cylinder with a piston and connected to the frame and the carriage so as to urge the carriage to move relative to the frame, wherein the cylinder is double-acting having;

    I. an extension port; and

    II. a retraction port, whereby hydraulic fluid supplied to the extension port urges the piston to extend from the cylinder and hydraulic fluid supplied to the retraction port urges the piston to retract into the cylinder; and

    (iii) a hydraulic pump connected to;

    I. the input transducer to receive at least some of its required input energy therefrom; and

    II. the cylinder to exchange hydraulic fluid therewith.
