I'm a bit confused about pronation. Is it the twisting of the racket using the wrist, elbow, or shoulder?

ADVthxANCE.

Pronation refers to the motion of the forearm/wrist. But don't think about it too hard. Concentrate on developing your other mechanics, and keeping your arm loose and active throughout the stroke, and pronation will take care of itself.

I didn't even know about pronation for about the first fifteen years I played. And when I saw a number of instructional pieces in a short period of time saying things like, "notice how the pro pronates his forearm during this part of the serve," I thought, OH ####! I DON'T DO THAT AT ALL!

Then I saw some video footage of myself, and discovered that I did.

If you tighten up, your body won't allow natural pronation. That's bad, and will rob you of power. But the root probelm won't be that you aren't pronating. It'll be that you're tight. Pronation is an effect, not a cause.

the whole arm anchored in the shoulder. there's flexibility in every joint though.

however, the max contribution to pronation is in the forearm.

I didn't read the thread in the link, but pronation of the wrist and forearm is definitely not just for the flat serve. In fact, you have to pronate your arm more drastically on a kick serve than a flat serve.

Pronation is another buzz word that tennis players like to refer to.. Supination, and so forth.. I like to call it the counter clockwise motion of the forearm, or rotating the palm down.

Thanks for all the feedback guys. Much appreciated it. I'm gonna be practicing my serve tomorrow morning some more and wanted to get a little more info before I started.

I taught my 9 year old daughter how to pronate with the forehand and 2handed-bh in 30 minutes... and she doesn't play tennis. The secret is you have to start the forward swing from pronation, then supinate and finish back in pronation. If you don't start from pronation, you won't end in pronation.

Same for the serve. All the strokes are the same swing in different places.

Roddick, for example, does not do this on his backhand. And therefore he doesn't have much of a backhand. No racquet speed.

I have never pronated purposely or drastically on any serve. Leave pronation alone! Your swing path, toss location, and the place you are SUPPOSE to hit the ball will put the desired spin in motion!

It starts with the forearm, and then the shoulder as you go through it.

Pronation is pretty good, on flat serves as well as kicking out the opposite way. My JV coach had a mean pronation. I tried to copy it, but obviously failed.

Here's my pronation -->

I honestly never knew I pronated that much until I videotaped myself. You might be pronating and not even know it. I never knew I pronated, until I took video heh.
