1. An exercise assist method, comprising:
receiving a user input signal from an external device;
measuring, in response to the user input signal being received, a joint angle of a hip joint of a user wearing an exercise assist device configured to assist the user in performing a leg movement; and
controlling torque of the exercise assist device to be applied to a leg of the user based on the measured joint angle,
wherein the controlling of the torque of the exercise assist device comprises,
controlling the exercise assist device to operate in an exercise assist mode and increase a magnitude of the torque for a first time period whenever the measured joint angle corresponds to the joint angle of the hip joint of the user at a time point at which the user input signal was previously received, and
controlling the exercise assist device to operate in a standby mode and decrease the magnitude of the torque for a second time period whenever a standing posture of the user is recognized based on the measured joint angle.
