Abstract: An exercise unit for applying a rectilinear vibration and a swing vibration to the user. The exercise unit is divided into a lateral vibration part and a swing vibration part which are driven by two separated driving motor respectively. The lateral vibration part converts a rotative motion of the motor into a rectilinear vibrating motion to provide the user with the rectilinear vibration. The swing vibration part converts the rotative motion into a swing vibrating motion to provide the user with the swing vibration. The two parts may be selectively driven by a single driving motor.
