A signal processing part (18) has a calculation section (181) which calculates the center point of the user's left foot by use of the detection results obtained by respective weight sensors (160, 161) for the left foot and calculates the center point of the user's right foot by use of the detection results obtained by respective weight sensors (170, 171) for the right foot. A judgment section (183) measures the displacement of the center point calculated by the calculation section (181) with respect to the center point of the ideal characteristic of the storage section (182) by each foot of the user. When the displacement is smaller than apreset threshold (5% of a distance from the origin to the center point of the ideal characteristic) in both of the right foot and the left foot, the judgment section (183) judges the action to be normal. When the displacement is not smaller than the threshold in at least the right or left foot, the judgment section (183) judges the action to be abnormal. A control section (180) stops a driving device (50) when the frequency of displacement not smaller than the threshold per a fixed period becomes not smaller than a preset frequency. This trains user's muscles effectively.
