Two players position themselves at the net opposite two players standing at the baseline. The coach/feeder stands with a basket of balls at one of the net posts on the same side as the net players.
Each point starts with a feed from the coach/feeder to the baseline team.
The baseline team will have 2 minutes to win as many points as they can against the net team. The net team doesn't count their points; they merely try to prevent the baseline team from accumulating too many points.
As soon as a point is over, the feeder will put another ball in play right away.
When the 2 minutes are up, the teams will switch sides - the net team moves to the baseline (while the baseline team will move to the net) and try to beat the other team’s (now play at the net) score.
Note: good drill for volleys under pressure; work-out. The players can also take turns rotating one spot clockwise after every 2 minutes.
