To provide an exercise system in which device miniaturization is achieved for simplifying the process of controlling interactive images.

This system comprises an exerciser 2A and an audiovisual device 3A controlled by wireless signals transmitted from remote controllers 1, 1A, with the remote controllers 1, 1A connected to the exerciser 2A. The exerciser 2A has operating condition detection means 20, 20A which output detection signals according to the operating conditions detected. The remote controllers 1, 1A automatically transmit control signals according to the detection signals inputted from the detection means 20, 20A of the exerciser 2A, to control the images projected on the audiovisual device 3A, and sound is outputted.
