How to train the coordination of left and right hands?

There are several ways: 1, hold the ball, face the wall, pat the ball with your fingers, not with your palm. Practice your left hand more. It's best to practice every day. 2. Do fake movements with your left hand. Don't put your right hand behind your back. Only use your left hand. It is normal for your hands to become stiff. Just practice more. (The same is true for the right hand) 3 Practice the shot put with the left hand (lead the team, ask the PE teacher if you don't know) and practice the finger flexibility. After more than 4 times of practice, you can hit the ball with your left hand or push it against the wall just like playing tennis. The most tired one is coming, dribbling back. First, turn around before school, dribble low and lean forward slightly, which is helpful for sprinting. But to tell the truth, I have been practicing on the school team for three years, and I am still prone to mistakes. Anyway, I have to keep practicing my basic skills, and there will be room for improvement.
