The next stage is the movement stage. Starting off from the last step of the preparation phase you have your elbow and the ball tucked into your side. A constant could be looking at the back of the rim, or the so called, "back of the iron." Next, you want to elevate the shoulder to where the ball rises above your head and shoot, while always focusing on the back of the iron. The story goes, feet shoulder width apart, elbow tucked, BEND the knees, extend the arms, and wave good-bye to the ball (the release of the ball). Notice I highlighted upon bending the knees. Bending the knees allows you to get into a rythm and to generate some force to help in the movement of the ball.
Scientific Terminology:
The movement stage has your neck in a slight extension looking up at the rim of the basketball hoop. Keeping both feet in anatomical position you want to flex at the knees slightly. While doing flexion at the knees you also want to have flexion at the glenohumeral joint parallel to the ground. Your upper extremities and the ball should be superior to your head.
The motion should occur in the sagittal plane and not break the mediolateral axis also known as the frontal-horizontal axis which is perpendicular to the sagittal plane.
