Thereafter, when the raised weight is lowered, the number detection sensor changes to ON and OFF again, and at this time, the number of training is recognized as one.

  These two types of sensors output the weight of the used weight detected by one number detection sensor and the number of training times detected by the other number detection sensor to the terminal as signals.

  The terminal includes a control unit that receives signals output from the two types of sensors, a display unit that displays a training status, and a recognition unit for recognizing a user. The terminal includes a host computer. It is connected to the.
