One of the most common things we see with students is that they hit down on the ball instead of swinging up and out.
This often leads to hitting into the net as well as other problems.
The big question of course is how do you avoid hitting down and how can you hit up and out.
Nadim has helped a lot of students recently with a very simple drill that is all about what you do with your non-hitting or tossing arm.
This is really interesting, and even I had never seen this drill before!
