The player (A) is just inside the service court. The coach (F) is on the opposite side of the net, inside the baseline, having a basket to feed balls from.
Drill:
The coach will feed only lobs for the player to practice overheads following these rules:
– for every ball (overhead) the player hits in, he gets +1
– for every ball he hits into the net or out, he loses 1 point (-1)
– the goal is to get to +5 and avoid -5 points.
Note:
For more advanced players they could be required to hit the ball to certain targets, more pace (hit the fence after one bounce in), or lose 3 points for a miss (out or into the net).

plus 5 minus 5 overhead
