Add variation to your overheads by using grip adjustments to create spin, making the ball harder to defend and allowing you to recover the net position.
The coach talks about adding variation to your overheads, especially using grip changes to create spin. This is useful because spin makes the ball harder for opponents to defend and gives you more time to recover the net. Learning to adjust your grip for different types of overheads, like an 'umbrella style' spin, can significantly improve your offensive options.
