Athletes sometimes sit on the ball, and sometimes lift the ball for jumping. These interesting movements make the whole process very entertaining. Thirdly, the exercise of fitness ball helps to train the balance ability of human body. In the past, fitness exercises were carried out on the ground or on stable equipment, so athletes did not have to think too much about the balance of their bodies. Fitness balls are different. Athletes leave the ground with the help of fitness balls. For example, sitting on a ball is a balancing exercise. Lifting one leg will increase the difficulty of balance. It will be more difficult to move the raised leg a little. When doing push-ups with legs on the ball and hands on the ball, athletes should first keep the balance of their bodies and prevent the ball from rolling, so they have to rely on the strength of their legs, waist and abdomen to control it, which makes the coordination of their bodies and the ability to control their muscles effectively trained.

The movement design of fitness ball exercises should make the human body fully contact with the spherical surface as far as possible, and the fitness ball is made of soft PVC material.

At the same time, the elasticity of the fitness ball can be used to correct the sitting posture. Therefore, sitting on the fitness ball, athletes will involuntarily straighten their backs and stretch their shoulders backwards.

Note: it is best for athletes who come to do fitness ball sports to wear tight clothes, because when doing sports, the human body will often touch the ball, and loose clothes will make the action invalid. At the same time, it is best to choose non-slip soles for shoes. Of course, this also needs to be considered according to the ground conditions of the fitness center.
