Fitness ball is one of the traditional health care devices in China. There are stones, steel, copper and others that only use two walnuts as balls. The reason why fitness ball is beneficial to physical fitness lies in the moderate movement of fingers and palms when playing, which regulates the meridians of the body. Playing fitness ball has the following advantages:

1. Fitness ball makes fingers, palms and wrists flex and stretch flexibly through the movement of fingers and palms, promotes the movement of upper limb muscles such as fingers, wrists and elbows, and prevents and corrects symptoms such as numbness, trembling and decreased grip strength of upper limbs caused by degenerative diseases of the elderly.

2. The fitness ball stimulates the second and third metacarpal bones of the palm, which is conducive to regulating the function of the central nervous system, achieving the effects of calming the nerves, strengthening the brain and improving intelligence, thus enhancing the physiological functions of internal organs and exerting the physiological effect of "moving is not bad".

It is an indisputable fact that hand exercise is good for the brain. When people play fitness ball, they can concentrate their thoughts on their hands, eliminate all kinds of distractions, eliminate tension and relax their brains. When playing fitness ball, the ball rotates regularly and makes a soft sound, just like sweet "music", which will undoubtedly balance the excitement and inhibition of brain nerves and relax appropriately. Moreover, hand movements can make the blood supply to the brain more adequate. Therefore, playing fitness balls regularly can effectively protect the brain, slow down brain aging and avoid the occurrence of Alzheimer's disease.

We should be patient, confident and persistent in playing fitness ball, and try to alternate with traditional fitness programs such as walking, practicing Qigong and playing Tai Ji Chuan to enhance the fitness effect.

Playing with young people is also good for your health.
