(and how to increase your arm speed, simply two requirements " soft arm and big arm" a soft arm makes it easy for you to do a perfect throwing mechanics and we can understand easily what a big arm is used for.) (how to increase your body speed. what you need is a strong leg and good command on your upper body ( the upper body rotates late but quick, and reach the max speed at the moment the ball is rereased) --
