GC187 Hit and Run (with targets)
This drill will handle a large group and it can be used with a cardio tennis class. Start by dividing your players into two lines starting behind the slash mark on one side and on the singles side line on the other baseline. The players near the singles side line can start with a courtesy feed or the pro can feed a running forehand to the first player(X1).  The first player hits it crosscourt to the target area and the player on that side (X2) tries to return that shot down the line to the other target area.  Players receive points for hitting through the targets. Players can either rotate to the other side of the court or back in their line after each hit.

Variations: Players receive more points for hitting the targets from the live shot.
