This drill uses the two sidelines of a basketball court. The object is for the players (who are lined up on one side of the court) to get outside of the lines.
First, have the team (or players) lined up on one side of the court. Then blow the whistle and before a player reaches the other side, blow it again. Keep doing it until you feel necessary to stop.
