Left Foot, Right Foot is an improvised song by Randy Newman about the Griffin family in "Da Boom". He survived the Y2K fiasco, and writes songs about his surroundings.

Passive exercise machine

In a signal processor 18, a calculation unit 181 calculates a center point of a load applied to a left-footrest on the basis of partial loads detected by left foot load sensors 160 and 161, and calculates a center point of a load applied to a right-footrest on the basis of partial loads detected by right foot load sensors 170 and 171. A judgment unit 183 measures a deviation between each of the center points calculated by the calculation unit 181 and the center point indicated by ideal characteristic curve stored in a storage unit 182. The judgment unit 183 determines a normal exercise when the both deviations are less than a predetermined threshold (5% of a distance from an original point to the center point indicated by the ideal characteristic curve). The judgment unit 183 determines an abnormal exercise when at least one of the deviations is not less than the predetermined threshold. A control unit 180 counts the number of times the deviation is not less than the predetermined threshold. When the counted number of times is not less than a predetermined number during a predetermined time, the control unit 180 deactivates a drive device 50. Accordingly, an exerciser's muscle is trained effectively.
