1. An exercising device including elements movable by the user to rotate an alternator means connected to absorb energy expended in operation of said device, means reacting proportional to the rotational speed of said alternator for controlling the force expended by the user, means for detecting the output of the alternator corresponding to the rate of expenditure of energy transferred to said alternator by said user, said detecting means producing an output;
- means for converting said output of the detecting means into electric pulses, each of said pulses having a magnitude proportional to a predetermined increment of said absorbed energy and an impulse advanced counter means for counting and visibly displaying the number of electric pulses produced by said converting means.

- 8. In combination, an alternator having a field winding and an alternating current output producing a voltage proportional to the rotational speed of said alternator, means for applying a rotational force to rotate said alternator a one shot multivibrator connected to one phase of said alternator tripping in synchronism with each alternation thereof, a rheostat in said multivibrator circuit manually adjustable to set the width of each pulse of said multivibrator, and means coupling said pulses to the alternator field winding producing direct current in said field winding having a magnitude proportional to the product of said alternator frequency and said pulse width.
