If the hand is not big, the practice method is the same as above, but it should also match the grain of the ball, so that your hand (mainly these three fingers) can buckle the two grains and practice more.
In addition:
First: if you want to catch a player, you must be big enough, that is, there is a lower limit.
Second, holding the ball really needs to hold the ball. When holding the ball, the hand fully touches the spherical surface, and at the same time, the ligaments of the hand are stretched, just as people who practice gymnastics and martial arts must adhere to leg press. If the practice is interrupted, the flexibility of the ligament will be reduced.
Thirdly, the quality of basketball also affects the stability of catching the ball. Generally speaking, the PU material, that is, the material of the game ball, is easier to grasp by hand. Moreover, the sweat on your hands and the dust on the ball will affect the effect of catching the ball. Therefore, it is best to keep your hands dry when catching the ball.
