1. An aerobic exercise training apparatus comprising:
a motor configured to apply a first rotational force in a first rotational direction;
a variable axial piston pump having a swash plate configured to be driven by the first rotational force;
a fluid motor having a rotatable component and defining a first aperture and second aperture, the fluid motor in fluid communication with the variable axial piston pump through a fluid loop, the fluid motor configured to rotate the rotatable component at a second rotational force in a second direction when a first fluid pressure is applied through the first aperture; and
a linkage configured for communication with a user and in mechanical communication with the rotatable component, at least a portion of the linkage configured to rotate in a third direction when a user applies a third force;
wherein the second direction and the third direction are the same direction or the second direction and the third direction are opposite directions.
