Should come as no surprise, but in our focus groups, the serve continues to be one of, if not the weakest part of a club-level player’s game (basically defined as USTA 5.0/5.5 rated players on down). We charted a match the other day between two high ranked USTA men tournament players (details are not important, and not posted in an attempt to not hurt anyone’s feelings). Bottomline — we don’t remember either player getting a single first serve in! Truthfully, maybe 1 out of 10 or 20. Second serves though were quite reliable but were ”fluffed up” to avoid a double fault and most any high level competitor would have killed either 2nd serve with return winners. We note for the record that even at the highest WTA levels of play, the women don’t count on their serves as a weapon but often just try to get the point started and try not to get hurt by their serve.
Here’s a summary of the biomechanics from one scientist. How much each body part and exertion contributes to racquet head speed and power. Obviously, you also need to master, integrate, mesh, and time the various exertions. The torso/trunk and legs are used to support these exertions and to add range of motion and pre-stretching to increase overall power.

Without starting an argument, we can probably all agree that a sound throwing motion (like a baseball pitcher) is an important part of the serve. Within the overall throwing exertion, we can isolate the shoulder and bicep and the proverbial external/internal shoulder rotation. Many, if not most, club-level serves suffer from poor mechanics which can be traced to a fundamental lack of throwing mechanics. Of course, one of our themes at eSticks.com is, once you “get it”, you need to “trust it”. There are many info resources for sound throwing mechanics, exercises, and tips for injury prevention. We will add details on the site to save time hunting around if needed — let us know.
