The Science of the Serve WRIST ACTION ("Wrist Snap" Myth BUSTED) 

This is a fantastic explanation of the wrist action! I’ve never understood the radial deviation part of the racket drop - so I’ve gone into wrist extension early. Your simple explanation of radial and ulnar deviation is amazingly helpful Coaches focus mostly on pronation but the earlier movements are subtle and important too. With much appreciation for your content and humor!

You're very welcome, you deserve all the kind comments. Not only are you both tremendously talented, on and off the court, but one gets the clear impression that you're both good people! Humble. And knowledgeable. One or both of you must be a kinesiologist/physical therapist/sports trainer, etc. as your knowledge of anatomy and biomechanics is solid. And your video production savvy is unparalleled, certainly the best among the tennis channels, hands down! All in all, you guys reign supreme, aka ROCK!!! Keep up the good work. Please! 😄 P.S. Love from Canada!

Definitely want that kick serve wrist action video: you are putting out the best biomechanics details available. Informative & usefully applicable.

Hi, buddies ! I need to thank you: after I watched this video I was able to understand and execute a serve with the fluidity necessary to be effective. Thank you so much to you guys for being the best on the internet. Bruno Lopes, Rio de Janeiro, Brazil.

Best tennis technique videos on youtube hands down!! Keep up the great content!

I'd love to see some match play videos of you guys in either, practice, UTR, USTA, or Interclub if it's ever possible. Everyone uses the pro's as examples which I understand, but it's always nice to see you guys plays as well.

Amazing lessons packed with gems and insights that I think only a few amateurs can actually appreciate and understand everything said in your videos. Keep up the great work. Cheers fro Brazil.

All your videos are so insightful! Your presentation is also lively and fun to listen to. As an additional visual enhancement, I’d like to see you pause the video at certain portions of the motion to see exactly what is being emphasized. Having it in slo mo is helpful, but pausing in places you are describing would Wally facilitate the illustration! Thanks fir all your great work!

You guys rock! Love the technical and in depth discussion in your videos.

OFC we want the kick video. You guys are the best!

You guys are simply awesome. I've learned so much from each of your videos. Please keep them coming. Cheers

Best video on proper technique for power serves ever! GOAT on Tennis serve video series hands down!

Thank you for sharing your expertise! Learned a lot! 👏🏾👍🏾👍🏾

Kick serve wrist action video? Yes please!

It’s a very useful tip and good lesson for the improvement on my serve. Thanks a lot

Your videos and your enthusiasm are inspiring.

Very professional video. Thanks for the great tips.

Amazing!! Fabuloso análisis. Excelente trabajo!!

Fantastic video guys. As a tennisplayer subscriber you've actually helped explain some things I didn't fully understand

Thia is such a piece of in-depth informarion!! Thank you very much! Congrats!

Thanks for your free teaching,I learn so much from your channel,your channel enhance my tennis technique a lot,i am so ecpecting your kick serve video will coming soon

Great video. Love your informative content. Thank you!!

So much great video footage from different angles. Nice.

Very informative video. Thank you!

Very informative video and yes, I would like to watch a video on the kick and topspin serve. Thanks

Fantastic lesson. Thanks!

Excellent analysis!!!!

thank you coach. your charisma and way to explain things is an inspiration for me as a coach6

Hello Guys, I am really enjoying you videos. Please, make some videos specifically for kick and slice serve technique. Your tips already making my serve better - especially leading with the elbow as Fed. does.

One important element to address is the angle between the racquet long axis and the arm, and the angle between the forearm and upper arm approaching contact. If either or worse both of these angles are not large enough, the internal rotation can put a lot of stress into your shoulder It will feel like the racquet is putting your arm in an armbar and you can't swing through smoothly.

Great video once again , I look forward to seeing a video on of the kick and if you could cover the slice serve which is more difficult ,that would be great

Send this video to Patrick Mouratoglou 😄

You're the best, Dude. I've learned soo much from you!! I've 'liked' all your vids

I would love a video on wrist action in the kick serve. Actually I love all your videos.

Great explanations.

Great video!!!

this is real! I have never heard like this detail explain. THanks!

Awesome explanation!

Can’t wait for the kick serve video! I can pronate on my flat serve but for some reason I stiffen my wrist on the kick serve

Would love to see a kick serve video on wrist action. I have a pretty good serve and I do actively pronate. And you are so right. The key to proper pronation is approaching the ball on edge. And you should aim straight for it. Any change in the path will lose power. You guys are the best in dissecting technique. Thanks.

You guys have awesome content! The best I would say.

Brilliant guys, thank you!!

Explained and demonstrated as good as anyone else, if not better. Now don't disappoint (lol), and do the kick and slice too. Simply put: extraordinarily well done!

AMAZING VIDEO!!

What a lovely, positive human being

Best video around!

I don’t know where you were hidden for all these time I was struggling, man you are so amazing, thank you so much

Yesss I'd be really nice a kick serve wrist snap video

we need kick serve content! amazing as always

Terima kasih atas tekniknya...👍👍🙏

Thank you, thank you!

Hi thanks for this video sir

Great lesson. 🎾👍 The graphic at 01:05 showing Fed to be "pronated" at trophy position is incorrect. The wrist has only 4 movements: flexion, extension, radial deviation and ulnar deviation. Pronation and Supination are forearm movements. Pronation is *NOT* a wrist movement. With regard to flexion/extension, Fed wrist position at trophy is neither flexed nor extended. Wrist is roughly in a neutral position. With regard to radial/ulnar deviation, Fed wrist position at trophy appears to be in a slightly ulnar deviated position.

Great video thanks, best explanation I've seen. So the wrist goes from ulnar deviation at trophy pose, to radial deviation at racket drop and as it goes through contact does flexion and also ulnar deviation again?

Your actions of service is very nice. Even the explanation is good. I would like to follow the same and apply in my game and see the results right from today. Thanking you, Yours regards.

Very nice....keep it up

This vidoe is a realy high level vidoe Thanks

Great video

Excellent analysis. My wrist fell apart 20 years ago, due to failure of the scaphoid-lunate ligament (after 30 years). The stubby ligament could not be repaired, it is surgically wired and pinned to prevent further damage. As a result, I have zero (0) wrist flexion, and about 2/3 the normal wrist extension. I still have moderate ulnar and radial deviation. My point is -- I had a very good serve, and thought for sure this operation would ruin my serve. False ! You don't really need any wrist flexion in the serve, almost all of the power comes from the other movements/sources that RacquetFlex describe in their serve videos. I used to wear a bowling wrist guard with a metal insert, (to lock my wrist) when I was in therapy, and was amazed how hard I could still serve (and the spin I could generate) with a "neutral" wrist. Yes, you need to maintain a loose wrist and relaxed grip, but that's so the arm, shoulder, etc don't also tighten....so don't be too rough on Mouratoglou !

Can’t wait for the Kick serve video tbh.

Buenisimo!!!! Exelente!!!!!

Can you elaborate more on the possible wrist injury in tennis? BTW, just subscribed your channel. Great knowledge and even better communication skills!!

Love your videos and instruction guys. Curious if you have kinesiology or biomechanics/medical training as your instruction is heavily laden with great tips that include this.Thanks again for your instruction and expertise.

Excellent bio mechanics. Next part the load of legs and horse kick. Well done.

Pls make a video on slice serve, thanks!!

Thank you !would you recommend if any step-by-step drills to build a "relax arm" serve? I got some pain of arm always on my serve, as you said I used to more arm to actively making the pronation , thanks in advance,

good stuff

Took the uspta cert with you guys, little did I know that you are making the best tennis videos RU-vid has to offer!! Keep it up, ps daytri commands that kick serve, no matter what Simon says;)

Please do the video about the wrist action in kick serve its really necessary

Bagus sekali untuk diikuti...👍👍

Hi guys anychance on doing a vidoe on the optimum volleys .or on optimal return stance

Ah it looks so easy, just a matter of managing to get there without completely wrecking your wrist, elbow, and shoulder. The most useful thing in that video by the way is when you said how it should feel. It's really difficult to copy instructions for something happening that fast, any time you can translate those into instructions into saying how it should feel in a way we can understand is very helpful.

Let's do that kick serve video !!!!!!

Love it😊😊😊

Also, you two look really good in this video!

Loves your videos. I’m coming back for that beautiful hair tho

I have a student (many, actually) who just cannot get out of their head the idea that the hand is supposed to go straight towards the target. They move their hand towards the box, then flex their wrist straight over, rather than rotating their entire racket, hand, arm, shoulder system. I try to explain to them that the hand goes one way, and the strings go another. I try to get them to swing with the edge, and explain that only the racket goes towards the target, the hand, arm, throwing motion goes off to the right (for righties). But they just keep turning towards the target. Any drills for someone who seems to have the waiter's tray pattern deeply ingrained? Not just waiter's tray purely, but also a hybrid where it's not totally waiter's tray, but it's only wrist flexion and no shoulder rotation, so it's still fundamentally pushing the hand towards the target then "snapping" (probably what they were taught to call it, at least; it's not very dynamic) the racket over the hand. (I'm not sure how well I explained this.)

Amazing

Catchy title but the wrist does snap into contact even if keeping the wrist relaxed allows more snap than trying to snap the wrist. I believe Elliot showed 30% of racquet head speed is transferred through wrist snap/flexion even though the wrist is still short of neutral at contact. The wrist flexes past contact also pretty much in all cases regardless of long axis rotation past contact or not but I’d hesitate to call it a snap. Mostly semantics, I just don’t like people saying there is no wrist snap when wrist extension and flexion is such an important part of the serve. There are people who will consciously try to keep their wrist from snapping after seeing “no wrist snap” or “wrist snap myth busted”. Personally, the feel I try for is radial deviation knowing that will lead to wrist snap.

Hi, just started learning tennis for past month and whenever I learn serve I always afraid that I will throw the racket, any suggestion?

What do you mean about pinky Flexion in the trophy Position?

Great and deep analysis of the serve details. What do you think guys - why many tennis pros don't even know about pronation and deviation(etc.) but hit precise bombs over 125mph? Because they just have it in muscle memory from childhood elite training?

Are there drills to achieve this?

kick serve wrist action video please @RacquetFlex

would you please make graphic explain percentage weight +power from leg ,hip, arm , trunk,wrist from toss until hit serve (in video clip)

Break down RF techs

yes kick please

YES!! KICK SERVE PLEASE..THIS IS COMPLEX!!!

yes, kick serve !

Please do the kick vid.

Kick Serve video plz!!

Guys thanks alot for your hard work, enthusiasm and kharisma ! Can you cover one day how to properly approach the ball And what is the proper way to move around the cort Thank you!

My favourite tennis channel though I gotta say I'd also subscribe if you had a hair channel 👌🏽😁😁

Thank my video coach sir I recovery my mistake please reply me sir I wil be waiting and one more thing please make video with right hand players and tell this comment on another video please 🥺🥺

Q.

0 thumbs down holy

Unlike your video on the wrist "action" on the backhand. This video was very helpful. The "shake the racquet" trick is an easy way to teach the wrist orientation and the looseness required. It really makes learning and teaching the "whip" part of the serve much easier

I thought that was Serena until he turned around

How come you're not a pro?

i think your racket grip size is waayyy too big
