Players put a hat on their head, while the coach feeds balls to the player. They must execute a forehand volley without the hat falling off their head.
In this drill, the player works on their head stability. Having a hat on the head is a visible indicator of success or failure. Firstly, the player learns how to hit without moving, before potentially adding movement to the drill to make it more challenging.
Having an unstable head is a reason for many mistakes, not only at the net but also when executing strokes on the baseline. Controlling the head is a necessity to improve body control and the effectiveness of the stroke.
