Do you often hit overheads into the net? If so, you may have forgotten an old, but useful, piece of advice. The next time you hit an overhead, reach for the sky with your non-hitting arm, point at the ball, and keep your arm up until a few moments before you make contact with the ball, as you would on a serve. This prevents you from dropping your shoulder or head too early and should ensure that your overheads clear the net.
