ABSTRACT:
An exercise machine and a method for its use in training selected muscle groups by controlled use of brakes to resist crank movement adjustably at specific and adjustable controlled positions in the rotation of a crank. A control system may be incorporated to cause brake mechanisms to apply varying amounts of resistance to a pair of pedal-driven cranks to simulate the efforts required to ride an actual bicycle over a course including various upslopes and down-slopes.
