The main source of strength for mid-distance jump shot is not the arm, but the four main sources of strength for running, stopping and jumping. Wrist and fingers, as well as a small amount of arm swing strength, are only needed in the case of long-distance jump shot.

The jump shot should be steady, and the four important items are shooting in situ, foot muscle strength, emergency stop action and step jump action. The basic in-situ shooting should be reasonable, or the in-situ shooting percentage should be at a certain level, so that you can reach a certain stable level in the moving jump shot; This is just like the old saying: if you can't walk, don't learn to run. Secondly, when your foot muscle strength is not good, the jump shot will be unstable when you want to jump, so your jump shot can't be stable; Again, if the muscle strength of your foot is poor and you stop suddenly, your jump shot will be unstable; Even if the muscle strength of the foot surface is not good, it will definitely be badly padded when preparing for the jump shot. In this way, your body must be in an unstable state, so, of course, your jump shot will not be stable.

And when you shoot well in situ, but you don't suddenly stop, the moving process will definitely not stop well, so your jump shot will definitely not be very stable. Then when you shoot in situ, it's good, but when you want to jump shot, you jump up and down, so your jump shot will not be very stable. Finally, I remind you that the more stable your arm is when you jump shot, the less you need arm strength. If you add the step of emergency stop, it is also very stable. At this time, the stability of jump shot is only a matter of the ball feeling of your wrist and fingers.
