Clinically, it has been proved that fitness ball has a significant effect on the treatment and prevention of hypertension, neurasthenia, cervical spondylosis and other chronic diseases, which is conducive to the prevention and treatment of nervous system diseases of hands and arms. Because the palms and fingers of both hands are closely connected with the internal and external organs of the body, all organs of the body have reflection points (or projection areas) on their hands. Pulling the ball with your fingers will cause the ball to massage and stimulate many parts of your palm. Finger activities involve several main meridians of your hand and some organs related to your fingers. So the fitness ball seems to be a local exercise on the surface, but it is actually a whole body fitness exercise. When choosing a fitness ball, it is mainly based on the size of the palm. Generally speaking, medium and small sizes are suitable for beginners. After proficiency, you can increase the model or increase the number of balls. Single-ball spin throwing: take a fitness ball in one hand and spin it in your hand, left or right. You can also rotate up and down. Take the ball with one hand and throw it up gently, so that the ball can be caught after leaving the palm of your hand, which increases the sense of space and the times. One-handed rotation and throwing are the basic movements in the initial practice, and both hands can practice with a ball at the same time. Double-ball rotation: hold two balls horizontally with one hand and turn them left or right with your fingers. You can also rotate up and down. You can practice with two balls in one hand, which is the most commonly used method. Three-ball rotation: Hold three balls horizontally with one hand and only rotate left or right. Practice alternately with your hands. Four-ball rotation: Hold three balls horizontally with one hand. To increase the weight, put another ball on it and turn it left or right. Practice alternately with your hands. Two-handed ball rolling: hold three balls or four balls in a string with one hand, and the two hands should have a proper distance and height to roll from one hand to the other. Throw two balls with one hand: hold two balls with one hand, throw one up, throw another ball when the ball falls, put the first ball in your hand, leave only one ball in your hand, and throw the other ball into the air above your hand repeatedly, and repeat the practice. This is the advantage of regular exercise with fitness balls. If you want to stay healthy, you can also treat your body through other therapies besides fitness balls.
