The coach (F) is behind the service line, and the player (A) begins the drill on the other side of the net, just inside the baseline (see graphic below).
Drill:
The coach feeds balls for the player to practice:
1. short ball attack
2. forehand volley
3. backhand volley
4. overhead
5. drop shot (after the ball bounces).
The player moves back and repeats at least 5 times before taking a 20-second break.
If there is more than one player, they take turns after each 5-ball sequence.
