Disclosed is an exercise management device using a hula hoop having a device for measuring the spinning direction and exercise amount, which enables balanced exercise in both directions and can automatically store exercise data and perform analysis. The exercise management device using a hula hoop comprises: an annular body part； a sensor unit comprising (a) a gyro sensor, provided on one side of the body part, for measuring an angular speed, (b) an acceleration sensor for measuring acceleration, and (c) a gravity sensor for detecting the direction of gravity； a hula hoop comprising a control unit comprising (1) a MICOM for receiving and analyzing a data value detected by the sensor unit and thus calculating the spinning speed, the spinning direction and the number of spins, thereby obtaining exercise information, or for transferring the data value, (2) a communication unit having a Bluetooth chip for transmitting the exercise information or the data value to the outside, and (3) a power unit for switching on/off the control unit by supplying or blocking power； and a wireless communication device having a dedicated program, installed thereon, for receiving the exercise information or the data value transmitted from the communication unit and then displaying the exercise information or displaying exercise information obtained by analyzing the data value and calculating the spinning speed, the spinning direction and the number of spins.
