Abstract: A counting device for counting repetitions and timing a push-up exercise includes a device body and a counter assembly having a display and a plurality of actuation buttons thereon. The counter assembly fits within a deformable foam ring that forms the top of the device. During exercise, a user depresses the foam ring downward with their chest a given distance so as to trigger at least one sensor in the counter assembly to register a repetition count on the display, along with an elapsed time of the exercise. The counter assembly can be fixed within the device, or a display unit thereof may be removable so that the device and display unit are configured for wireless communication.
