Anytime you can work on a players conditioning while you are also working a basketball skill like shooting, ball handling, etc. you maximize your time. This is a basketball mid range shooting drill that is going to allow you to work on your shot, but it is also going to let you work on building up your conditioning as well.
Another great thing that this drill will do, is help the player learn to shoot when they are tired, and to stay mentally strong as their body gets fatigued. The more tired they become the more their shooting fundamentals will struggle, so it is important that the player locks in and shoots the correct way, regardless of whether they are tired.
