Master the Serve Kinetic Chain ft. Jeff Salzenstein

[@TomAllsopp]

It was great working with Jeff, and there will be a great backhand video on his channel shortly. His continuous serve motion helps with basic fundamentals. The loading the back leg is something I hadn't associated with the racket drop, and I'm excited to go experiment with it.

[@JimArthurVanWyck]

The back and forth between the. 2 coaches is wonderful..

[@ronwest8499]

Loved the video. I find that at 64 years old I get the most benefit from the guy who keeps it simple. 😀

[@dougtennis5147]

This conversation was ABSOLUTELY AMAZING. Coached fifteen years and you two coming from different sides (in a way) and meeting in the middle, and not necessarily fully agreeing, while providing in depth ideas about the biomechanics that ALL MADE SENSE, and was full of thought provoking instruction. I often would bring a football (American) to a lesson to teach kids how to throw one on the plane to me, and then show them how the serve itself was more of an upward throw (that still goes forward). Elbow, wrist, racquet. This helped them get the continuous throwing motion down. As for me now, I've really been working on the wrist movement that Jeff spoke of at the top of the trophy pose. Kyrgios actually starts that wrist position at the beginning of his serve take back. (another channel pointed that out recently.) For some reason doing that move has helped me loosen up a lot. I think I can serve almost 80 now! (JK, 95, lol).

[@mayabergom]

Yes, I'd love to see more back-and-forth like this! It's really cool to hear the coaches' different approaches. And the interesting thing is that they agree a lot on what good serves do - and indeed their own serves look super similar - but how do you get someone there? That's where some of the differences become more stark.

[@dougtennis5147]

@@mayabergom What Tom did so well is explain how the serve is taught to different levels with different approaches. What works to get the 3.0/3.5 on track won't be the same for an advanced 8+ UTR, but the fundamentals taught early can lead to the possibility of a more advanced serve. The frying pan grip and square faced bump serve will obviously get no one there. At the advanced level, it is amazing how serves are like finger prints, each one different. What Sampras,Goran and Becker were doing in the 90's could not have been farther apart, and yet we consider all three to be some of the best serves of the time. Becker, for example, used an eastern forehand grip and his right leg actually came forward (while in the air) whereas most players kick their right leg back. What I like about Tom is that he is always teaching to find the mechanics that work for your particular "fingerprint" while staying true to what actually works. Your question of how do you get someone there, in Tom's case, requires him to have multiple answers at the ready knowing there might be very specific answers that work for specific players.

[@mayabergom]

@@dougtennis5147 Well said. Totally agree.

[@lavanchung9428]

Super excited! In my opinion, I prefer your throwing motion to Jef style. For me, Jef style is a little old and more advanced to practice.

[@barisay7244]

Yes Jeff's style is too advanced for most players, but it still is the better serve. Very Sampras-like.

[@Johnstage]

You can’t go from a panhandle grip serve to Sampras serve motion in one shot. All about progressions. Both emphasize steps. Excellent video!

Two good coaches with self confidence to show that there's more than one way to teach tennis. Well done.

[@grantdelmege2724]

Interesting video guys. This just goes to show that there's more than one way to serve. In ny opinion the Sampras racket drop technique is the best but it is more advanced as you need more flexibility to do so. However Stan Wawrinka has an old school back scratch racket drop and he can serve well over 130mph. I think as long as you have good fundamentals and a good throwing motion, it doesn't matter too much how you drop the racket behind your back. But to add fuel to the debate, Rick Macci does say that the racket drop is a dynamic movement due to the leg drive and hip rotation. This is how Roddick served over 150mph whilst only being 6ft 2. Great debate and tutorial.

[@ryanmitchell9460]

Great idea to do this guys. Really enjoyed you bouncing tips of each other

[@omarsultanov362]

This is my dream vid on tennis. For everybody else it's a recommended MUST VID ON THE SERVE. JS was the 1st who did clear the mess with my serve. This mess was partially due to the instructional mess and not only in the KZbin but amongst pros as well. Believe me I got a lot of lessons and advices from the the former and present ATP and WTA PLAYERS alike. The result - two broken tendons of my shoulder and USD54K operation with Dr. LaFosse in Geneva. Though 40 min drive to his personal clinic in France to Aneccy could spare me more then USD30K..But I was not aware and it's not highly relevant here and now. Conclusion - if the one serves really well that one not necessarily can teach the serve not even well but even at all. The cheetah 🐆 can run, who argues? Can it teach you to run? Doubt it... So the experience with JS was that you need the COACH and not the player. Prior I bumped into TA and his TPA Tennis JS was the only authority. Now they are two. And both made the unbelievable session in this vid. What is absolutely fantastic they address the slight nuances of their attitudes and this is besides being awesome by itself helps enormously to better understand the nature of the serve for the more facets you are aware of the less dogmatic and more flexible you are becoming in the comprehension of what really suits you...Awesome unsurpassed vid. Bravo 👏 👏 👏

[@insighttennisacademy9421]

Nice to see two coaches discuss in public without having the same way of teaching. I would say the throwing motion and continious movement drill are quite the same and both a nice base and crucial before developing advanced stuff. I would like to add that the throwing motion itself isn’t the hardest part. It’s throwing the racket at the bal (at the right time and place) which is the hardest. So just like on the groundstrokes rhythm, timing and spacing is crucial. So drills with a bigger ball (volleyball serve) or lighter ball wich travels slower so its makes the timing less hard, will help make the transition from a throwing a ball to throwing the racket at the ball. Finally, hitting the ball in the “small” box hinders the free throwing motion. So serving against the fence or between just in the singels court is crucial for this transition! Best, Paul

[@TomAllsopp]

Thanks for the great comment. I wish I could make things as easy and slow as you do in Europe. There’s a stigma here that slower balls etc are a hindering growth rather than helping. Players unfortunately find it patronizing.

[@tepian2]

Love the side by side slow motion comparison at 0:31. You can see the differences in how the racket drops "on edge" vs a more "open face" motion and how they relate to the teaching mechanics of throwing/leading with the elbow vs loading the back leg. Great discussion and insight!

[@TomAllsopp]

One difference I noticed was the guy on the right drinks a lot less beer haha

[@jeanb.3493]

Great video and discussion. Made me think about criticism in the comment sections on some of the shorts that Moratouglou has put out, and the thing most of these criticism have in common: they fail to see that teacher's advice has to be seen in context, which has to take into account the person in front of him, and what piece of advice will be most effective. Teaching a novice tennis player that is a highly skilled football (soccer) player will be very different from one that is a highly skilled frisbee golf player. One will have great movement skills and ability to leverage the legs and hips into the kinetic chain, the other will have great throwing skills and ability to leverage the upper body torso rotation.

[@mayabergom]

Yes, I totally agree. Tips like "don't break the plane" or "load on the back leg" might be super helpful or supremely unhelpful - it all depends on where the player is in their development

[@TomAllsopp]

Working with people, not on people is what coaching is all about!

[@omarsultanov362]

PM is perhaps one of the greatest coaches ever and for sure now amongst live ones. Two things though with his serve teaching embarass me - the left arm not being tucked in but artificially going with the whole body anti-clockwise. Allegedly a-la Thiem. But Thiem does it after he INITIALLY TUCKES IN THE LEFT ARM TO THE CHEST. After and not instead. Secondly, the idea of PM that for the slice serve ONE MUST AVOID PRONATION. With this regard I don't have the slightest idea how to comment this - so absurd and unreal the whole idea is...I am very much afraid that PM does teach the topspin serve without pronation as well OMG, though I'm not 100% sure. But JS does. And if this is the case, then they are both IMHO wrong, and wrong very very seriously. Tom teaching in this regards looks the most modern, natural and up-to-date - one does pronation at any f... serve, as simple as that 💪🏿👋😊

[@nekobx2094]

So, another Coach and myself was chatting about this today. Everyone has their own natural abilities that lends to each player. That is somewhat why professionals look different on their service motions. Some have more shoulder usage, etc. However, there is something about developing a throwing motion. Just throwing a lot....whether it's a football or baseball dramatically helps the service motion. I think because it's the most natural way to use the body if your throwing an object. Sometimes, I feel that as coaches we over analyze how a particular professional does something in their own natural state (however somethings are manufactured). But lending to a student's very own abilities is sometimes lost and learning something can get too "technical". There was a lot of nice tidbits and gems in this video. I really appreciate it. Also, I made my own weighted throwing object but it's so cheap it breaks all the time. 🤷‍♀️

[@swalterstennis]

Tom, GREAT video. I agreed a lot of with how you teach the serve to intermediates and some of what Jeff says which applies to high performance players. There are different efficient ways to get a nice serve and win the point. People’s bodies and skills are different and there are multiple ways to help people. I’m a former ATP coach and have extensive USTA HP training and I’ve taught 60,000 hours and I’m constantly learning. I’ll continue to watch and learn from you. Keep it up.

[@TomAllsopp]

Thanks Steve. Great points. Totally agree. It’s about working with people, not on people, figuring out what they need and helping them in the simplest way possible. Always learning, and definitely learned a few things from Jeff.

[@swalterstennis]

Awesome. Merry Christmas champ. And, I agree with you. First get them a good throwing motion, and then add the legs and the grip.

[@NamesAreRandom]

I took the throwing motion you essentially taught me and used that, it has worked very well to give me basic a flat serve with pronation, a top spin serve where I throw without rotating (so stay side on) only straightening up and pronating afterwards, and a slice serve using the topspin motion with side cut. I can even have a go at whipping the pronation like a pro at the cost of some accuracy on my flat serve. As long as I keep varying the serve type and direction it's good enough to win me points at my level, it doesn't wreck my body and it's a great start for "proper" serving so big thanks to you. However my motion however is far too compact to give me anything close to a 100mph serve. I have been using RacquetFlex's serve videos to take it forward from there (in my opinion they are clear and helpful). Suggest you have a look at them - they basically talk about the same thing Jeff does using the rotation/leg push to get the racket to drop along with a number of other helpful hints such racket angle in trophy phase, body angle and angle of arm in relation to body as you hit the serve.

[@vectorthurm]

3.5-4.0 player here with my own perspective. I believe Salzenstein style is more feel based and using big (lower/core) muscles that can lead to more relaxation upstairs. I’m personally experiencing better results with this than thinking about throwing mechanics, etc. For me, focusing on throwing leads me more into trying to “manufacture” the stroke rather than relaxing and “allowing” the stroke to happen.

[@Better_Call_Raul]

The idea that improving the throwing motion will translate into a better serve is clear. Practiced throwing tennis balls from baseline to baseline. Eventually able to hit the back fence after two months. And over the back fence after three months. My 3.5 serve improved from 75 mph to 90 mph.

Amazing video, Tom and Jeff. Thank you for the outstanding dialog showing abundant mutual respect, and understanding that there is more than one way to get a great serve. Very much depends on the student, and a great instructor will help him/her get the what works optimally for them. Tom - on a separate issue, I’d like to ask you about your perspective on feet positioning on the platform serve, given your excellent grasp of biomechanics whilst also possessing an advanced level golf swing. Traditional teaching has the feet closed to the line of serve direction for platform stance. This is completely at odds with modern golf swing ideology where the idea is to create resistance by differential shoulder and hip rotation going back to facilitate faster torso uncoiling on the through swing (“X Factor”). If the same concept applies, would it not be more efficient to start with the feet less closed for the platform stance? Interested to hear your thoughts on this, not necessarily now but perhaps when you have the time and you feel it worthwhile discussing (if ever). For whatever it’s worth, I serve platform with feet closed in classical manner. However, I also played scratch golf for many years and the difference in concept has always been at the back of my mind.

[@Mickey_McD]

Great to see a collab between Tom and Jeff. Interesting how they do come from different places for serve technique. I think that Tom is right that leading with the elbow is critical and that working on good throwing motion is how to get there. It was interesting that Jeff mentioned keeping a loose grip to enable the racquet drop -- I've been experimenting with Tom's idea in a previous video that it's OK to have a firmer grip as long as you keep your elbow loose. This seems to work for me. Not sure how it affects my racquet drop, however.

[@TomAllsopp]

I think there’s a balance, so depending on who I’m working with it I might say the complete opposite thing haha. But basically I approach it like my old fashioned cocktails, the perfect balance of sweet and bitter, or in this case loose and firm 😆

Your Jeff impression gave you more rotation. It's the one thing I noticed in your serve you weren't doing. You opened up quite a bit more trying to serve like him. Your left shoulder finished behind your right because of that more complete rotation. It looked really good, really natural.

[@TomAllsopp]

That’s not an issue I have with my serve. If anything, I open up too much when I serve. I stay more sideways doing Jeff’s motion

[@mightbefire]

@@TomAllsopp Yeah, after watching some more videos, I see what you're saying. Your rotation looks good. In the first few I saw you weren't rotating much.

[@dadmaxx8127]

Interesting that you talked about the shoulder because, for me, once I took the shoulder out of the power equation, the power was easier and my shoulder never hurts from serving. My shoulder rotates, but I never try to use it for a power source...for me, the shoulder rotates, the elbow brakes (slows way down) and this sequence allows the forearm to pronate at a super quick rate which gives me the power I desire.

On every high level serve the racket on the drop is away from the body not close to the head and body, which is the result of acceleration and opening the shoulder, body. A big misconception, in my opinion, is learning the serve with the racquet drop close to the head. I see the racket close to the head on the trophy pose but on the drop, I don't see any high-level tennis player doing that, for example, Fed, Djokovic, Nadal.

[@marktace1]

I think you are a little off on your understanding of how to throw a fastball. Most pitchers have external rotation much more similar to what Jeff was showing. Some older pitchers who have less external rotation range of motion will compensate by flexing the elbow more. Take a look at young vs. old Roger Clemens for example. Infielders will also flex the elbow (cock the ball by their ear) when throwing, but they are gaining quickness at the expense of speed. That’s not a good trade when serving.
