Live Arm 2.0

[2022 Edition] 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.
