If you’re a doubles player and you struggle with anticipation, then I want to invite you to pick up a copy of “The Little Black Book Of Tells,” because inside there are 52 tells that will allow you to predict where the ball is going to cross the net, so you’ll know whether to poach, cover the alley, or cover the lob.

A “tell” is something your opponent does that tips you off about where they’re about to hit. And the 52 tells from inside the book come from some of the greatest players and coaches of all time, including Martina Navratilova, the Bryan Brothers, and Gigi Fernandez.

But you don’t have to be a world-class athlete to use them because it’s just about recognition! Check out the video above and I’ll show you one of my favorite tells so you can see if it’s right for you.
