An isometric exerciser formed by a pair of spaced bodies joined together by a link associated with a transducer and ensheathed in a cover to define a structure having a generally oblong configuration. By grasping the ends of the exerciser in his hands, a user is able to exert a compressive or tension force on the transducer. The transducer converts this force into a corresponding electrical value that is applied to a pulse generator coupled to a loudspeaker housed within the structure, thereby producing a train of audible pulses whose repetition rate, tone and amplitude depend on the applied force. Thus the user receives a continuous audible feedback, permitting him to adjust the applied force to a desired level. By means of a counter responsive to the output of the pulse generator, one is able to score the user's performance.
