One team of two players, at the baseline, on each side (team A-B and team C-D).
One feeder at the net on one side (F).
The team on the same side as the feeder is the defending team (team A-B).
The feeder sends balls to team C-D (attacking team) as follows: 1 short ball to bring them up to the net; 1 volley; 1 overhead.
They play each point out. For every point they win, the teams count it.
After teams play the third ball (the overhead), team C-D moves back to the baseline and players switch sides (the player on the ad side moves to the deuce). The cycle repeats with both teams playing the three points (short ball, volley, and overhead).
The defending team (team A-B) switches places after every six points (the player on the deuce side moves to the ad side).
– Play first to 11 then teams switch sides of the court.

Note: This is a great drill to work on net play and defense; and also improve volleys and overheads in a competitive situation.
