Do you know why you should not look back when your partner is hitting the shot? It seems like the thing to do because you have to know where the ball is at all times don't you? The answer is yes, you must know where the ball is at ALL times, but you must also know where your opponents are at ALL times. The ball and your opponents combine tell you where to go on the court. If you do not know where the opponents are how do you know whether you can attack or defend. Let me give you a couple of examples: I. You are at the net and the ball is hit deep to your partner at the baseline and the opponents rush net. You should back up and play defense. 2. You are at the net and the ball is hit deep to your partner at the baseline, but your opponents stay back at the baseline. You should stay at the net and keep the attack position. So you see it is important to know where your opponents are as they are part of the answer as to where should I go while the ball is traveling to my partner. Looking at your partner hit the ball and ignoring the opponents will not allow you to be in the correct position every time. This is a hard habit to break, but trust me, once you do you will be amazed at how much better you play.
