There are several reasons for poor jumper:
1. A bad sense of the ball means that you can't feel the ball sticking to your hand, which is the same as a breakthrough dribble. Therefore, if you want to find a sense of ball, practicing dribbling often is the best way to find a sense of ball.
2. Bad rhythm means that you have no sense of rhythm when shooting. Whether it is an emergency jump shot or a fixed-point jump shot, you must have your own rhythm. Look at Pierce, the jump shot is not very high, but people just can't get it. This is your own sense of rhythm. You often practice shooting and emergency jump shots.
3. The posture is not standard. Although some people are not allowed, they are still very good, but most people still choose the standard shooting positions. The standard shooting posture is three 90 degrees, wrist and forearm are 90 degrees, forearm and forearm are 90 degrees, and shooting arm and body are 90 degrees in space. Practice more by yourself.
4. Just because your waist strength is not good enough, strengthening your waist strength is the basis of air body coordination, which can be strengthened by doing 100 sit-ups every day.
