Net Gain is my name for Alejandro Ciffoni's series of net drills in the May/June 2014 issue of
TennisPro Magazine. You will need at least four players.
Two players are at net. The other two are across the net at the service line. Goal is to rally 8-12 times with the player straight ahead of you. Net player is aiming for a spot (real or imagined) in the middle of the service box. Net player should attempt to hit a variety of shots to the returning player's backhand and forehand. Once rally goal is met, players switch spots.
When all players have met the first goal, move returners location to halfway between service line an baseline. Net player is now aiming for service line area. Repeat exercise until all players have had a chance at both positions.
Finally, move returners to baseline. Net players are aiming for the mid-court area.
Remind your players this is a cooperative activity to achieve the rally goal, not an opportunity for the net player to blast winner after winner.
If your players are not to the level where they can return these volleys effectively and maintain a rally, set up a generous target for them to aim at instead and make it a target goal rather than a rally goal.
