Serve without a return player: Practicing wide high bouncing kick serves to the ad side.
In this drill the player only practices wide kick serves from the ad side. The player tries to give the ball enough spin so that it passes through a target set up at an appropriate distance on the baseline or over a string stretched over the net. This controls the learning objective.
A total of 3 series with 20 serves each are to be performed. After each series there will be a short break. This way the players get a relatively high amount of training. Of course, this can also be done in groups of 2. Then, for example, a player can do some useful mobility exercises for his shoulder or elbow during the break.
Practicing the serve in isolation to a specific target area from a fixed position (like here from the advantage side) serves as a base for further tactical training.
Although the focus is on the second serve, it can make sense to practice the combination (first and second).
