Please keep in mind that I advised the OP not to employ a kick serve (in post #14) if he cannot figure out an implementation that doesn't tax the back.
Don't know much facet joints
Don't know much about history
Don't know much biology
Don't know much about a science book,
Don't know much about the french I took...
Doesn't matter whether I am familiar with facet joints or not. I do know what stress to the lower back feels like. As mentioned, I have a history of lower back problems. A lot of bending forward (to pick up things) can stress my back. Some other activities that include twisting and extension of the back can stress my back. I can perform an implementation of a kick serve that will also stress my lower back...
However, I have also developed an implementation of the kick serve that does not appear to stress my lower back. I know other players with back problems who can execute kick serves without repercussions to the lower back. It appears that Federer can also do this.
Pushing the hips forward, as Jeff Salzenstein advises (post #5), is one of the ways to implement the kick serve motion w/ very little stress to the lower back. Also, heels UP.
Hm, it's seeming like you don't know much about the lower and mid back facet joints. Your personal observations don't mean anything. The stress on those joints that I'm talking about would not be visible. Also, the lower-mid vertebrae are already arched in their natural resting position.
It isn't really a meaningful discussion. You're going to believe what you believe based on your implementation of the kick serve and watching a Federer video. That's fine. In these times, I don't really get involved in trying to convince anybody of anything. Nobody believes anything anymore.
But my advice to OP still stands. Ditch the kick serve. Develop a good slice. If OP's back doesn't like the kick serve, I encourage him to save his back, not injure himself further, and think about his future health.
