One of the players (A) is at the baseline, the opposite player (B) begins the drill inside the service box; both players use only half court (doubles alley included).
Player A is allowed to hit only lobs; player B must tap the net with his racquet after each overhead.
Drill:
A starts the point with a lob; B will return it and the two play the point out keeping the ball only inside the half court.
Considering that player B will have to run up to the net to tap it after every shot, this can be an exhausting drill for this particular player.
Play first to win 7 points then switch sides and roles.
Drill recommended to advanced players.
