Fitness device provided with heating device

The invention discloses a fitness device provided with a heating device. The fitness device comprises a pair of massaging apparatuses, wherein the pair of massaging apparatuses are rotatably and symmetrically arranged on a back cushion; each massaging apparatus comprises a shell as well as a motor, a gear set, a heating device and a massaging rotary disc which are arranged in the shell; the gear sets are connected between the motors and the massaging rotary discs; the massaging rotary discs protrude the shells; the motors, by virtue of the gear sets, can be used for driving the massaging rotary discs to rotate; the heating devices are arranged under the massaging rotary discs; and the motors and the heating devices are electrically connected to an external power supply. Since the massaging rotary discs, which can be used for implementing rotary massaging on a human body, and the heating devices, which can be used for conducting thermal therapy, are integrated, a neck or shoulders can be massaged through rotat
