Do not stop at contact but rather time your feet so that you land with the back foot, hit the ball, and then land with the front foot. So on a forehand volley, you want to make contact as your left foot is still steppping forward, before it comes down. Does this make sense?
good advice. many players think "I have to get at least to the service line for the first volley" and then keep running no matter where the ball is.
of course it is better to hit the first volley in front of the serve line but it is better to hit a volley 2 feet behind the line that overrunning it.
