An electromagnetically regulated exerciser providing a variable proportioned resistance to the exercising user. A user input device is drivingly connected to a rotatable shaft. Permanent magnets mounted on the shaft rotate within a wound stator. The windings of the stator are electrically loaded by an electronic controller to create proportioned isokinetic exercise resistance. Motion of the input device by the user is opposed by dynamic braking forces generated by the electrical loading device, and the resistance increases proportionally as the user exceeds a preselected reference speed, effectively regulating user induced motion generally at the preselected reference speed.
