The controller can judge what state the supine plate is in the first, second and third states according to which one of the first, second and third light receivers receives the light emitted by the laser emitter. And when the exerciser is supine, the head touches and presses the pressure sensor, so that the measured value of the pressure sensor is changed from a state smaller than the set threshold value to a state larger than or equal to the set threshold value, thus the exerciser is supine once, and the supine time is recorded as the first state supine time, the second state supine time or the third state supine time by combining whether the first, second and third light emitters receive signals or not. Namely, each supination time is marked with time information and state information (a first state, a second state or a third state) to be stored in a storage unit, so that subsequent inquiry is facilitated. When a time period is selected, the total number of supination times of each state in the time period can be inquired.
