Abstract
A device for pacing a series of exercise repetitions whereby, in one mode, the user interrupts a light beam with each repetition and a light signal indicates if the period for each repetition is longer than a preset value. In a second mode, the user performs a single event beginning at a position remote from the light beam and finishes the event by interrupting the light beam and a signal light indicates if time for the single event is longer than a preset period.
Claims6
An exercise apparatus which comprises:
- a photocell light source having a photocell beam;
- a photocell sensor on which shines said photocell beam which is located so that a user performing repetitions of an exercise interrupts said beam shining on said sensor when he assumes a desired position during each repetition and so that a repetition period between successive interruptions of said beam is the time required to perform each repetition;
- means for preregistering an arbitrary pacer period;
- means for comparing each said repetition period to said pacer period;
- a signalling means which emits a signal each time any said repetition period is longer than said pacer period.
