Playing basketball, the footwall is unstable, the body coordination is poor, and the flexibility is not good. How to practice?

Hehe, your situation is quite special. There is a good exercise method for poor physical coordination, which is skipping rope. Jumping rope can enhance the coordination of the body. You can bounce back, tie a sandbag and run every morning (as long as your weight suits you). Then I started dribbling and running. Personally, I feel that the crotch needs to change direction. If you dribble well with both hands, you can change direction quickly. Then I feel that there is nothing under my legs. Mainly dribble more and practice your hands. Hehe, extra points
