This is a great workout for developing a player's reflexes and reaction time. In a game there are what we call "50/50 balls," and these are lose balls that either team has the ability to get. This quickness and speed workout is going to helps with your reaction time, so that when you see a lose ball you will be able to react quicker and get to the ball before the other team. It is also designed to work on the players over all quickness and reaction time. Whether it is for a lose ball or something else, it is important to be able to quickly react and get moving.
