I just started to play tennis in the park at the age of 40 and You pushed me forward with this video 2 years :) :) :) Thanks. Many aces are landing against novice mates. Amazing video. Thanks
Michael Biggins same here, i watched the other day the serve drill using half full water bottle. I love it, can hardly wait to start practicing these drills!
Yes I agree 100%, I see a lot of coaches fail to explain these details fearing too much information. I believe every player is different, some require detail and some may pick it up faster with less detail. I'm the detailed type, thank you for the excellent detail and practice example! James you are awesome at this!
Throwing "only the elbow" with the rest of the arm coming along for the ride instead of throwing the "whole arm" has been a major factor in improving my serve. And this critical aspect has mostly been de-emphasized or omitted by most other instructors. Thanks.
James, thanks for another really interesting video. Big kudos for making the vid short and to the point unlike so many others who talk talk talk with only a minor part of the vid allocated to the actual demonstration.
worked on this today.my serve didn't go in a lot.stuck with it for the second set oh what a difference a first serve makes.James you rock man.thx so much for your marvellous skills. best Haydyn
This video has helped me with the right to left movement perhaps more than any other video. I hadn't realized that the elbow begins bending and leading forward as the racquet is over the head, and I had instead been allowing the racquet head to travel past the left side of my head which produced an awkward movement nothing like what I see gracefully executed in the videos. Thank you.
The 2 videos I watched from you explain in detail the mechanics and progression of movement of the service motion so much better than anything else on the internet, even the ones from professional level instructors. Thank you so very much. I'm 52 years old 5 foot 7 and I can now crank out 100+ mph serves with ease.
Hi James... Mick here... met you on an OTI weekend in Abingdon a few years ago. Great vid Mate... very useful. The water bottle one is fab too. Cheers!
I noticed my tennis partner with the misconception of the right to left move bending at the wrist instead of the elbow and sent your perfect explanation and drills. Thanks again lets hope he doesn't start serving me of the court.
Thank you so much for posting this video. I took the 10 day serve and return challenge; it completely changed my serve game. I can’t wait to get back on the courts and show off!! This was a great follow up to the 10 day challenge. I love OTI!!!
I've been trying to undo my abbreviated takeback for a few months, but my focus has been on the racquet head, not the elbow. And I've been trying to fix this on the court. This exercise should really help me memorize the elbow position I've been unable to achieve doing hundreds of practice serves. Great job. Thank you.
Going to try this tonight, looks like a great tip to help keep that optimal angle of the arm! I know I tend to get lazy and drop my elbow too low. I'm ignoring the comments from the wanna-be coaches who can't seem to grasp this is one tip to help a certain aspect of the serve, if you want to go into depth regarding the total biomechanics and kenetic chain etc. get the OTI service course.
Oh my gosh thank you so much! I'm a futbol (soccer) player trying to keep my tennis player daughter in shape. I know nothing about tennis so your instructions are so helpful and clear and I can easily work with her on this. Thank you from Hawaii!
Great tips James. We are quite often rained out of lessons here in Atlanta, but I am going to tell my students to do this practice next to the wall at home on rainy days. You are right; the mechanics are easier to learn off the court and will eventually be a habit that carries over to the court with the proper technique.
This video is exactly what I needed to see. I love the way it's broken down to the most basic form. You completely answered my question about the starting position with the serve. Thank you so much, I know it will help my serve .
Really well done video! I think Jeff Salzenstein had a similar idea called "elbow the enemy", but I don't think even he realized that the tip helps not only with keeping the upper arm level with the shoulder, but also to keep the upper arm in a straight line with the shoulder line.
Hey James - nice to see you in front of the camera. I’m worried about my serve deteriorating during the pandemic - this is a great drill to help me keep grooving on key fundamentals. Thanks for posting!
Awesome insight on the serve! I was one of those player who drop the elbow to my body for 30 years. However, this tip will help me overcome my terrible habit that I have engrained in me. Wonderful tip!
Fantastic Video, think you saved my elbow, been serving the wrong way for a long time, and it was causing elbow problems. Much more power now with less effort. Thanks
Thank you. This works. After practicing, I went out and used it on the court today and I could feel the difference in the motion and the speed of the ball. love it.
Thank you. I subbed. It is easier to follow the motion you describe without a racket than with one. Good job to break it down into the two "bite size" elements.
fantastic explanation... i wud love this guy to also suggest a drill to improve ball release from the left hand. wud be really nice and useful indeed !
I am trying to improve my 1st server. I used to be with my body, with 45 degrees to the court. I am 64, for me is dificult to corret. But I keep on trying. I did not use the momentum, before. But one thing I notíced is that my right leg, as I begin to move my elbow and twist my body, goes in the direction of the other leg. Before my legs stayed in the same position. I am doing more mistakes, but I am looking foward to improving my first server. I liked your tips. Studing and practicing.
Happy to have found your videos. You have a clarity and simplicity that goes a long way. Can't wait to try the swing up and elbow motion tips! Thank you!
This is great instructional video for the hardest thing in tennis i.e. serving. However, sometimes getting beginners to concentrate on more than one thing at a time can be confusing and just too technical to remember. Great for more advanced club players but difficult for beginners to learn and grasp the nuances. The best basic instruction I've seen for 'beginners' to learn the service motion (for the racquet hand) is essentially to just throw a tennis ball as if you were throwing it as fast as you can but with a loose arm as this motion virtually replicates (but not totally) what the racquet hand should be doing in the service motion (not including the other key aspects like, the throwing hand, foot placement, body pivoting, etc). Simple I know but quite effective. A more advanced version of this is to go to the park with an 'old' tennis racquet and essentially just throw the tennis racquet (on grass and without hitting anyone!) forward as you would if you were throwing a ball. Try it it really does work.
Sorry Dr Ken...This instruction is 'TOTALLY'" wrong for execution of the serve.. As you know ..If some one had held a Hammer as flimsily as this guy holding a racquet...one would THUMP their THUMB 9 of 10 times..!
@@braxtonshrianandan2438 If I wasn't shut in at home, I'd go out immediately and try it. Everyone's biomechanics are a bit different. My question has been when do I begin to move the elbow forward and he seems to have answered that.
I’ve watched 100 videos on serving. I still don’t get the racquet drop loop thing. I can do it it all day without tossing a ball. The minute the ball is part of the equation my brain locks up. Your video gives me hope. I’m hoping I can get it now. I’m 70. I’ve been playing steady for 30 yrs. So I have a lot of bad muscle memory to change. What’s funny is I’ve been happy with my serve till 5 yrs ago. I videotaped my serve and I was shocked how horrible I looked. It’s like thinking your face is beautiful. Then you look in mirror and your totally disfigured. Wish I never had looked in mirror.
Please send me an email at florian@onlinetennisinstruction.com and I will give you something very important to help with your serve transformation free of charge!
Your serves are so much better than mine although my swing is faster, I have a jump and more forward movement. I've been trying to get this right for years and done lots of the online courses including the OTI serve blueprint. But.. it just ain't happening. My fast serves just hit the next, my top spin is too fluffy. Do you offer private lessons? I could do with spending a day with you !!

@@josjochems8368 There is no dispute about it, but once you finish what is called progression one in the video you can make simple throwing motion in horizontal direction. Why to push your elbow forward? You need to involve back muscles, not triceps.
@@liborstanislav3648 I agree with your last sentence about the back muscles. But I try to avoid that the recreational players have to think that the serve is a throwing motion. Because for a serve the movement and the elbow need to be UPWARD (not forward ). The HINGE is the SHOULDER for a serve , not the elbow or the wrist ( turn the underarm for pronation). It's more as throwing a broom and not throwing e.g. a ball or a stone. And one must feel the momentum of the racket head by not squeezing the racket (let the racket do the work).
Thanks for the feedback! :) Yes, when you bend from the elbow, it will move very slightly. But we want to strive towards keeping it on that imaginary post as stated in the video until the racket moves over your head approximately...then the elbow will begin to come around and lead to contact
Good morning! English is not my native language as my name can not hide. So maybe I make some mistakes. First of all, very good, excellent. I'm trying to improve my serve. But you could talk about the bent of the pulse also. And also grip the racket more far from the head. Good tip. I'm trainning like kata karete. I have broken some vases yet. I subscribed.
Thanks for the feedback Pedro :) May i quickly clarify your question, when you say 'bend of the pulse', do you mean the bend i have with my wrist? the way it is bent forward. please let me know. Thanks :)

Everything perfect till about 5:06. You should not move your elbow forward before shoulders rotation. The elbow is supposed to go forward as the consequence of shoulders rotations. The serve is still throwing motion.
