Work on speed and positioning with these hand-fed drills from former World No. 1 doubles champion and USPTA Professional Emilio Sánchez Vicario. Taught at the famed Sanchez-Casal Academy, these exercises allow you to work on your forehand and backhand groundstrokes both offensively and defensively. There are three main drills, all of which can be broken down into smaller exercises ranging in difficulty, that combine to form one intense exercise that will improve your tennis game. They improve your balance, control, footwork and stamina, which is great if you want to go that extra step further than your opponent.
