Okay, I hear you...
I learned from World Tennis magazine as much as I could. That's all well and good. A player from my high school team went to Macci's academy for 4 months. When he came back he had a kick serve ( no one else had one) proper footwork etc etc it was unbelievable. And that was only four months.
I'm basically a self taught 4.0. We practiced a ton in high school in a cold weather state (NY). All the "awesome" high school players I ever saw at the time had instruction all of them. Not one did not.
I still do not have a kick serve with any reliability. Every player in Macci's camp had a kick serve it's one of the first things they taught him.
...I agree that for most people, self taught will only take you so far. You want help with a kick serve? No problem, I'll tell you what I know. Just FYI, my background is that I'm 61, have been playing tournament tennis since I was 10, stopping playing for a while and got into bike racing, got back into tennis seriously about 5 years ago when I was fortunate enough to have the Head and Assistant Men's coaches at Colorado University, Boulder, and subsequently, the #2 player, as my coaches.
They didn't do it for free, but they put everything they had into working to help me improve my game, which is what happened. I taught skiing for 6 years, and am an Alpine L3 certified PSIA instructor. 20 years ago, I got into Masters Alpine racing, and have had a ton of good coaches in that arena. I am now USSA Coaches Level 1 certified and coach in my Masters training program. I don't yet have any official tennis coaching certification, but I've done a bunch of it, and the players I've coached really like my approach. I'm probably going to get certified and coach, because...well, I like coaching and I really want to help people play better tennis.
Hard to do any wholistic coaching over the net, but I'll give you some concepts on a kick serve that my coach last summer used to jack up my kick serve:
- The ball toss has to end up coming down about on the top of your head. That's because initially you have to hit
up at the ball, then snap and bring it down into the court. Think of it as you're trying to throw your hand up above a shower curtain rod, then snap your wrist and hang your wrist on the curtain rod. Most people try to snap out and down. The first move has to be up through the bottom of the ball,
then out and down.
- A kick serve isn't a casual, easy stroke. It's a different motion than a flat or slice serve, but you have to really put a lot of oomph into it...legs, torso drive, wrist snap at the end, the whole package. Otherwise, you may not get enough top to keep the ball in the service box (it needs to go deep) or it may kick up softly...and become a helium ball that the opponent can whale on. As Pancho Gonzalez once said, put some heft into the serve, every time. True of kick serves, particularly.
- Until you get the motion and the results you want, don't worry about placing it. Just blast the ball right down the middle of the service box...which, if you aim right at your opponent's right hip, isn't a bad shot, either...
