An electronic physical trainer system which produces periodic tone signals at an adjustable rate to establish an exercise rhythm and which senses the calisthenic activity of a performer in response to this rhythm to evaluate and improve his performance. The trainer system includes a position sensor in the form of a light beam directed toward a photodetector in a path traversing an exercise area to produce action pulses which reflect the movement of the performer as he alternately blocks and clears the beam path. Also included in the system is a pulse generator whose frequency is adjustable to produce exercise pulses which activate a tone generator whose output is amplified and reproduced to provide the tone signals. The exercise pulses and the action pulses are compared in a coincidence network which yields a "hit" pulse each time an action pulse overlaps an exercise pulse to a degree exceeding a set value and which otherwise yields a "miss" pulse. The hit and miss pulses are separately counted and displayed to score the performance.
