An apparatus for testing and teaching the lifting capacity and technique of a user includes a brake or clutch for resisting user input force which is controlled by feedback from sensors through a computer. Several operating modes can be chosen, including isometric, isokinetic, isotonic and a special accommodating isotonic which simulates lifting a real object as long as the user exerts enough force, but decreases a resisting force when it is more than the user can handle. A motor is used to substantially eliminate inherent system resistance.
