If you struggle with anticipation, you might be interested in “The Little Black Book Of Tells,” because inside there are 52 tells that show you how to predict where the tennis ball is going to cross the net, so you know when to poach, cover the alley, and cover the lob.

A “tell” is something your opponent does that tips you off about where they’re going to hit. Inside the book we share 52 tells from Martina Navratilova, the Bryan Brothers, Gigi Fernandez, and many other doubles experts.

These tells are the perfect complement to the plays Martina is about to show you in her “Rule The Net” poster, so if you want to increase your anticipatory powers, click the button to add it to your order.
