Live Arm 1.0

There are two ways to serve faster. The first way is to improve your technique, which is what most players try to do. The second way is to develop a "live arm" -- imagine being able to accelerate your arm like a Formula 1 racecar. The 10 exercises and 4 stretches in Live Arm will make your shoulder and arm more flexible, explosive, and stable at contact, which means very soon you'll be serving much, much faster.
