Four Corners - Short Court

One feeder sends balls from inside the service court, the other player is on the other side of the net behind the service line.
The player executes alternating ground-strokes and volleys as follows: one forehand ground-stroke at right service court corner, one forehand volley (closer to the net), one backhand ground-stroke at left service court corner and one backhand volley (closer to the net).
The cycle repeats.
Do about 7 repetitions.
Note: Good drill for footwork, quick recovery, control on the run.
