sampras has the best motion in the game............wait............yep he does (or did).
Trying to imitate the Sampras motion is a recipe for disaster for the average player. Sampras uses all the techniques that make the "classic" motion effective, and exaggerates them beyond the abilities of common mortals.
Where most try to get a little sideways in their starting positions, and more radical (McEnroe) style servers get the whole way there, Sampras actually goes beyond this and almost turns away from the net to start.
Where most try to toss/lean into the court, and the more amazingly athletic incorporate a lean and explosion up from the court that almost launches them forward, Sampras's lean and explosion was at a nearly 45 degree angle...at full extension...and airborne. Most people try that, and they won't just stumble, they'll fall flat on their faces.
Where most try to incorporate a shoulder turn, and a few of the best REALLY turn their torsos before unwinding, Sampras practically twists himself till he faces the other direction. Unless you're a pro-level athlete with yoga training to boot, you're asking for a ruptured disk and chronic lower back trouble if you emulate him.
Sampras was one of tennis's most finely tuned athletes EVER. His raw athleticism, and more importantly his FLEXIBILITY put him in the top percent of the top percent. His body was made of rubber. His service motion, if executed in an exact copy by the average 4.5 level player, would have him in traction.
The ELEMENTS of Pete's serve are worth studying and emulating. But if you try to re-produce his results, you're either going to fall far short of them and wind up with an exaggerated but ineffective serve, or you're going to hurt yourself. Unless you're willing to spend your days on the physical training aspect of developing an elite pro-athlete body, a Sampras-style serve remains out of the reach of mere mortals.
Something like Federer's, which incorporates the same elements, but without the rubber-bodied exaggerations, is much more practical for everyone without physical abilities in the 99.99th percentile. Even something like Roddick's, which is far less mainstream, is still not as physically demanding to reproduce.
