Second, the specific steps are as follows:

1. There is an air plug on the yoga ball, which is basically white. First, use air to pull out the "white air plug" on the ball;

2. Gently insert the air pump into the air hole;

3. Keep pressing the air pump until the yoga ball bulges slowly. When the size of the ball is close to the full ball scale, it is the appropriate size of the ball;

4. Pull out the trachea;

5. Quickly insert the air plug;

6. Plug hard and move quickly, or you will run away. Generally, yoga balls should not be inflated too much. Seven or eight achievements are enough. Because the ball will become very hard when it is full, yoga will not work, and it is easy for people to fall down against the ball.
