Provided is an exercise information display system including a sensor unit attached to an ankle of one leg of a human body to output data on a motion state of the leg and a control unit processing the data. The control unit acquires a parameter based on data output from the sensor unit in a case where the human body performs a calibration motion for acquiring the parameter expressing at least one of an attachment orientation and an attachment position in the one leg of the sensor unit and a posture of the one leg in standing on the one leg, generates a reproduction image where a motion state of the leg during the exercise is reproduced in pseudo manner based on data output from the sensor unit in a case where the human body performs exercise of moving the leg and the parameter, and displays an image including at least the reproduction image as exercise information on the display unit.
