I've noticed that virtually every pro has their chest angled upwards as they during the cartwheel motion of their serve (moving the front shoulder down and the back shoulder up).
Example from Djokovic: http://www.youtube.com/watch?v=NO1X4m7FOuI
This activates different muscles than if the chest not angled up. To me it seems like the same muscles that would be used if a person were to throw a javelin.

It's also similar to if you put your arm to your side, kept your arm straight, and threw a tennis ball using your chest muscles to use your whole arm.
I really don't think most players use their chest muscles during the serve (including myself).
