I’ve stopped using the expression “racquet back” while coaching. Instead I’m saying “racquet ready”. Here’s the difference. Most of the errors I observe while coaching or observing play come from too much backswing resulting in late hits. Backswing gives us power, but not necessarily enough control. It’s better to prepare for a good consistent stroke in tennis with a “unit turn”. A unit turn involves turning the shoulders and the racquet simultaneously. To do this, pretend you have an eye on your shoulder. As the ball approaches, watch the ball through your imaginary eye on your shoulder. This prepares the racquet more efficiently, avoids late hits, and cuts down on unforced errors. Now, hit through the ball with more confidence and enjoy your game!
