IMPROVE YOUR RADAR - USE LASER TRAINING FOR FAST BALL TRACKING. As tennis has gotten faster, it has gotten harder to track the ball at high speeds. You may find yourself in a situation where guessing is taking the place of anticipation. Carlos Teixeira, fitness coach to top ATP and WTA players, shows you a simple drill that can increase your reaction speed and hand-eye coordination to stay sharp on the court. Using a laser pointer, have someone point the light at a wall and try to react and catch the light as soon as you can. This will train your eyes to react quick and your hand to get the message from your eyes faster!
