Preparation Phase

When preparing for a jump shot the player will bend slightly at the knees.  The throwing arm (depending on if the player is right or left handed) will be flexed 90 degrees at the elbow, elevated and placed under the ball.  This placement will allow for the player to better control the direction of the throw. The support arm (depending on if the player is right or left handed) will be flexed about 45 degrees, elevated and placed lightly on the side of the ball as a guide when throwing.
