According to the theory of traditional Chinese medicine, the human body is a whole interconnected by the meridian system from the inside out. Each hand has six meridians connecting the head and chest, and from there leads to the whole body. Moreover, there are many sensitive acupoints on the meridians at the ends of fingers, palms and backs of hands. Stimulating these acupoints can improve and enhance the physiological function of human body, and the fitness ball produces different degrees of rhythmic stimulation to related acupoints and meridians through the activities of hands and balls.

Traditional Chinese medicine research has also proved that long-term exercise with fitness balls can not only regulate the central nervous system, enhance memory, develop intelligence, improve thinking ability, eliminate brain fatigue, but also reconcile qi and blood, relax muscles and tendons, and strengthen the internal organs. Regular use of fitness balls for exercise has a good therapeutic and health care effect on hypertension, neurasthenia, hand neuritis, muscle spasm, upper limb (especially hand) dysfunction after stroke, fingertip paralysis, arm fatigue, upper limb arthritis, poor blood circulation in hands and other diseases.
