Position 4 cones one or two steps behind the baseline, starting near the doubles line until the center of the court. Post another two cones further behind to run around them after the player has hit his forehand. Watch video above (if you haven’t already done) to check out the cone positions.
Practicing with the coach:
Once the players are ready, player 1 starts moving around the front cones, while the next player gets to the runs around the cones to the starting position (player 1 starting position). Once the player, who is running around the cones reaches the last cone, the coach feeds the Ball and which is to be hit into the target area (deep cross-court forehand). Player 1 then runs around the back cones, while the next player starts to slalom around the front cones.
With only two players this is a very tough exercise and I suggest to repeat this drill from 10 to 15 hits each and then giving them a little rest. With more players, as there will be some waiting time, you can do more than that.
Practicing with friends:
It can be done. If you are only 2, one of you needs to agree to feed the ball while the other does the exercise, and then change. If you do not have any cones you can use something different. But do not use tennis balls as there could be a risk of injury if you trip over them.
