This drill comes to us from Mr. Frercks Hartwig who is currently associated as a tennis coach and player devepoler at TMS - Die mobile Tennisschule in Baden-Wurttemberg, Germany.

Thank you, Mr. Hartwig, for submitting this drill to CAtennis.com. We hope that all of you take the time to incorporate it into your tennis development process. The drill is as follows:

1. Draw a line about 1meter (3ft inside each baseline).

2. While the ball is in play, the doubles-players may not over-step this line.

3. The players are encouraged to take the ball early - either off a half-volley, regular volley or swinging volley.

4. The coach alternates feeds from A to B and points are played up 12. Feeds are to be mixed in terms of height, depth, pace and spin in order to put the receivers in the position to make a variety of adjustments [Editor's Note: there may or might not be "re-dos" for missed feeds; coach's choice depending on the level of the players]

5. Immediately after the feed, both teams proceed to move in and engage in a volley-volley exchange. By being forced to move in, the "volley-shy" players learn that it's more effective to win points at the net than at baseline.

6. This drill can also be performed by either (a) having the A-B team hit a groundstroke first; (b) having the teams sprint in from behind the baseline at the same time or (c) by moving the "artificial" baseline forwards or backwards to take into account the skills of the players.
