The coach sets up two targets, one in the deep corner for the players forehand cross-court, and another one shorter on the other side for the players inside out shot. On the other side there will be a cone in the center of the court on the baseline, to make the player run around it.
Practicing with the coach:
The first ball the coach feeds goes to the players forehand. It can bee deep, but not too deap, as we want the player to be able to hit the ball with an agressive topspin cross-court shot.
The player sidesteps behind the cone. Once the player reaches the cone (a little bit before that is also ok), the coach feeds the second ball short to the players backhand side. Give the ball some higth on this feed as we want the player to go for an agressive inside out winnter.
Repeat for around 10 times (20 balls), give the player a small break and repeat (do 3 sessions). You also can repeat if for more than 10 times.
Practicing with friends:
You can either rotate the feeder and do excactly as described above. Or you can make a game out of it:
The winner of each point starts the next one (don’t bee to mean on your feeds ;P). Play the first ball exactly as described above, the player on the other side plays a forehand cross-court, the feeder plays a short slice. Like in the exercise the player tries to finish the point. If the other player gets to it, play out the point.
Play up to 11 points. Or choose how many points you want to play up to.
