This definitely works. I'm surprised it is so controversial. When you look at most of the top servers in pro strokes, they are leaning back and hitting the ball over their head in this fashion on both first and second serves. You're the only guy I've seen recommend it, much less explain why it works. Nice work.

A simple experiment of racket head speed like this against a wall is hard to argue against. The concern I would like to note is that serving this way may "overly" isolate the shoulder muscles in the serve risking to contribute to some chronic tennis shoulder injuries e.g. anterior deltoid shift (shoulder sits too far forward), decreased shoulder internal rotation (limited range of motion due to overuse from hitting serves and forehands), outright pain or discomfort due to impingement in these muscles due to adaptation in the muscle over time e.g. hypertrophy. How to manage this? The simple answer I believe is to apply the concept of the kinetic chain fully - ensuring that the tennis player focuses on having power and impact forces transfer thru the body instead of having then isolated in the shoulder unit. In my own case I focus on actively contracting my upper core muscles (rectus sheath etc.) as part of my pre-serve ritual to ensure that they are turned on and that they will take some of the impact forces during the service motion itself. Practitioners interested in knowing more can see a recently released article on rehabbing tennis shoulder injuries: http://bjsm.bmj.com/cgi/content/abstract/42/3/165

Great insight on how to get more power instead of reaching as high as you can. Once again, Jim gives us great insight on how to really play the game, rather than old false beliefs.
