This drill will help you become the best shooter around, tust me. It involves a rigorous amount of movement, and shooting under pressure.
Take 50 shots from anywhere on 1 half of the court (# of shots you want do can be changed if you want it to). Keep track of the ratio of shots hit:total shots taken (this is why you need partner). Try to do this drill at full speed.
If you do not hit at least 50% of the shots you have to do 3 push-ups/ every shot you took, and didn't make 50% of your shots.
DO NOT CHEAT. YOU WOULD BE ONLY CHEATING YOURSELF.
Can be done with 1, but I suggest 2.
