Jannik Sinner Forehand Analysis | The Secret To Gigantic Power 

Sinner has reportedly Confessed in a church about the source of his forehand gigantic power...where it comes from.

Good analysis on the racket position, etc.. But we forget that there is a big difference in the leg movement between the slow and fast forehand. He steps forward into the court for the fast forehand, whereas he remains static on the slow one.

Fantastic analysis! Really interesting.

one of the best tennis channels on youtube by far ! Great Job man !

All you need to do is listen to Sinner's shots to know he's operating at a more efficient level than most pros. It sounds different - it pops. Rublev punishes the ball but he exerts far more effort, and I'd argue Sinner gets way more power based on the technique you break down in this excellent analysis. it's incredible to watch - i would love to see him play live.

4:10 note that he doesn't force this position... The body/shoulder rotation gets his racket in this position... That's how he gets power

Astonishing mate!

Just to mention it: on the fast vs. slow forehand comparison sinner is getting a slice ball from the opponent on the faster forehand, which forces him to go more into the knees and lift the ball more from the ground and on the "slow" forehand he gets an normally high spin ball from the opponent, which could also explain some of the differences.

another great video !!👏👏

Excellent presentation. Lucid analysis.

Great video. In my opinion the match between him and Carlos US open 2022 was a defining match. When we look years from now and have to identify one match that changed the future of tennis, it will be this one. Kinda similar in concept to " the changing of the guard match between Roger and Pete decades ago" These two played a brand of amazing tennis never seen before or never thought possible!

Fascinating!

Fantastic, highly detailed scientific analysis!👏👍THANKS. He’s only 19 and he’ll definitely get even better in his twenties.👍

Great and useful analysis

Sinner gets unbelievable racket head speed!

One thing I see Jannik Sinner doing different than a lot of the pros is his more frequent use of the neutral stance forehand. Just to resolve terminology differences, some people call neutral stance a closed stance. What Jannik is doing in the video I would describe as a neutral stance. A neutral stance forehand will let you transfer much more forward momentum which comes from moving your whole body forward. Semi-open stance and open-stance rely more on body rotation, and so your position is a bit more static. But with the neutral stance you have a foot in front of you that you can transfer your weight to, therefore it's much easier to get forward momentum into the shot. The drawback, of course, is you have to work your feet harder to get into a neutral stance position vs semi-open/open stance. Also, it's harder to respond to faster incoming balls with neutral stance. But, if you want to generate power, and you have the time, neutral stance is the way to go. You can see in this video example Jannik does a shuffle step into his neutral stance forehand. This adds even more forward momentum. His racquet lag is pretty extreme in this shot, but I do see other pro players getting that much racquet lag, e.g., Nadal.

Great analysis.

Perfect 👌👌 thanks for sharing 🤗

Great analysis 👏🏽👏🏽👏🏽

great analysis

Great job Jason! 👏🏼👏🏼💪🏼 This is a greaat video! I think his is a semi western close to bevel 3, with a small grip size to his hand. And great point on his more wrist extension while petting the dog to later have that massive lag for bomb shots. Great eye and analysis Jason!

Thanks Jason This morning I tried this and I was able to keep my wrists 3/10 tension first time ever and got a lot of racket head speed Many thanks

Super interesting!

Great video❤

I loved your explanation. I converted my Simona Halep forehand to the Sinner forehand in 30 minutes thanks to you!

Excellent teaching! Comparing different shots from the same player! Please compare above shoulder v hip level double backhands. Some players jump, others stay grounded on the above shoulder height balls. Thank you

1.first time viewer of your content and i absolutely love it. 2. Basically if we could generate whip like in badminton, this would be a future.3 maybe you could do osaka forehand analysis, because she really impressed me in ao. Women were in right sight of court just m from ball, but couldnt reach it.

well done respect

Great vid ! 🙌

He has a closed stance and steps forward more than some of the other atp players with good forehands. I tend to catch mine late when they hit a heavy ball to shoulder height because my backswing is too loopy. I will try to shorten it more like this but without the racquet head flip

Pause @ 3:45 and that is the key to his effortless racquet head speed. All the top players have extremely live wrists. The last second whip is so important. There's no tension in his arm.

Jason really nice work! Can you do one for the backhand also?

The coiling is especially huge in the fast one because of the the plyometrics of the forehand karaoke step that he makes into the ball. That said, he also has a lighter racket than almost all of the other pro’s...

Good analysis

Thanks for the video. My forehand is even more extreme..pretty much same elbow height but a bigger tilt, dropping the racket even more and huge lag behind. If I get the timinig and speed right, the forehand is high quality but it's highly inconsistent. It's very hard to correct and make it more simple (at least how Sinner is doing it) but I'm trying

This is 2 years ago. Now he is even better crazy

Hi Jason, a question: At 04:20 the stringbed faces the back fence at first and then, when Sinner starts the forward motion, the racket flips and the stringbed is pointed forwards. Does this change of the stringbed orientation happen naturally because he is moving the racket forward or is he doing the flip on purpose/actively with his wrist? I'm trying to copy some elements of his forehand, but always struggle on this part of his motion, because I try to turn the wrist so that the stringbed faces forward. I guess it should happen naturally instead?

Amazing

The tip of his racquet is "flipping" back BECAUSE of the looseness of his entire arm during the powerful leg and hip driven initiation of the forward swing. It is not something he is "doing". It is a result of everything he did prior to starting the forward swing. The reason Sinner (as well as Kyrgios, Sock and Tiafoe) lift the elbow and allow the tip of their racquet to point forward (the forward "tilt") during their preparation is because they are maximally pre-stretching the rotator cuff bands in their hitting shoulder which will also help accelerate the arm and racquet.

Excellent level of detail. But what is the reason for the tip having to be below the hand at impact to get spin? What is the physics of that? I would think that it's simply the upward momentum at contact that matters.

Sinner’s forehand is an absolute rocket. Does he have the best forehand of all the next gen players?

I tried this today just hitting out of my hand, it added pop and spin. Great tip I'm definitely going to start hitting this way.

Just found this channel. Have you guys done this for the Wrarinka backhand?

just to confirm, the transition of the racquet flip to the point where Sinner hits the ball is done using supination of the arm right (the parts where you talk about his elbow movement) - it's not simply using the wrist because you can see the whole arm turn in a clockwise manner (supinate) in order for the racquet face to flip properly. also regarding the tip of the racquet being behind the elbow - it would be good to remind viewers that it's a result of his unit turn and power loading that causes that racquet to 'lag' behind the elbow for his rocket forehand (i.e. the myth of wrist lag / snap) thank you for your analysis!

Incredibile. Orgoglio italiano.

what a wrist, I see now why he hit so many big shots, but counting on it too much might generate wrist problem if not careful. And also on side to side comparison on slow and fast forehand form, eventhough it is really useful, I think it is not a really a good exact comparison, since on the fast forehand you see that ball is going to cross court, compare to slow one which is on the middle, where in generally when you hitting cross court shot you need to also do more longer swing which interpreted in Sinner case by doing prolonged wrist whip move

Great video! Next up Sinner's backhand analysis?

Hi Jason, thanks for your video. For me, when I play tournaments or represent my club team, what is difficult is to plan my day for a lot of things to do. Program my day to get up, eat, digest, warm up, play competitive tennis and recover. I have so much to do, that I do not do what is important. I happened to have three matches in one day and it was not easy to plan my day and prepare to play the semi-finals the next morning. I hope this gives you some suggestions for a new video, which can help a lot of people. Thanks.

the ball on the left bounces higher, therefore his racket tip is below his elbow, whereas the contact point of ball on the right is low. Will be great to do a comparison of his swing on 2 incoming balls with same height, same depth, but diff pace (3 degrees, 2 are the same , 1 diff). that will be a more accurate comparison. Thank you for the analysis.

Keep it simple. It's all about rotating. Coil up and then recoil. The torso should pull the passive (loose) racket arm around, with the racket head coming from below the contact point (for topspin). Check out Powerflail... Most tennis coaches way over-complicate things and don't get their pupils rotating, so they have to use their arms (actively), often leading to tennis elbow problems.

Awesomeness

Jason, You are the tech. digger. If there are 10 levels depth, other coach only can reach 1 to 5 level, you can dig deeper and deeper to the bottom.

After watching your video I tried it for kicks. The ball hit the baseline, server didn't have time to get ready for the return, it was my fastest forehand in 60 years man did it rip. I did feel wear & tear in shoulder something to consider. Watching this after my first rocket launch success I notice Janek has his index finger higher up racket. Another potential point of injury. Make sure you're relaxed, try hitting ball out in front not behind. Del Potro warms up 4 hrs prior to every match to avoid injury on injury. Just saying. I was astonished with power from this forehand but hit as cleanly as possible. Your body will thank you for it!

I'm not very well versed in tennis technique, but I would think the different orientation of the racket in the "cranking shot" with respect to the slower ball, is mostly caused by Sinner bending deeper to find contact with the low ball. When bending deeper, the racket which would normally be facing the floor, will naturally tilt to the back side. This also means there's a kind of "double coil" going on, one due to hip rotation and one due to leg thrust. Somewhat paradoxically, the low position of the ball allows for unleashing more power, using this uncoil & thrust. On higher balls, the power of the legs can't be fully used into the shot because they're already stretched out when going into contact. Finally, the difference between the two shots also lies in the trajectory: the "cranking shot" has a smaller net coverage, so that when the topspin drags it down again, there's less time needed to find the court, plus more power goes into the forward motion. I think it's somewhat misleading to point to the "excessive flip" orientation as the root cause for the extra power. I would say it's more like a symptom of the real root cause, which is the deeper bend. Now I repeat my disclaimer: I'm merely an observant analyst, not having any experience with tennis coaching whatsoever. So I'm happy to stand corrected. PS - with all this, I'm also under the impression Sinner DOES actively add "flip" to the "lag", which I had always thought to be a kinetic consequence of the core movement. In this slo-mo video, it seems that not all of the flip can be attributed to lag only. See comment below.

He has a quick snap on his shot he hits with a lot of topspin. Great player🙌🏼

Hi Jason, great content! Could you analyse Lorenzo Musetti's forehand as well?

I thought maybe the difference is in the stance and the height of the ball in the two forehands. In the slower forehand, he is in almost a semi-open stance. In the first forehand, his stance was completely closed or maybe even past closed. He might not be loading or bending enough so the elbow looks to be lower but on the lower ball, the elbow might be in the same position as the high one but with him bending his knees to get lower for the low ball maybe the elbow seems higher? I think the biomechanics of both swings may be the same but because of the different stance positions, and heights of the ball the two swings may look different. I feel that if you have to consciously cock the racquet to where the racquet head is facing the back fence like in the first forehand, it would be hard to be relaxed and probably have to muscle the shot? Also if you are consciously making these adjustments instead of letting the footwork, stance, technique, and biomechanics of a modern ATP forehand swing do their job unconsciously, then it would be hard to build consistency right? Especially at that level with the big hitters and in long matches where you get fatigued? This is just a theory from an amateur, would love to learn where and what is wrong with my theory so I learn and get better. Thank you.

Also seems different from Sock in that the elbow does not whip forward in the same way. Instead the arm is swung as more of a unit, with all the whipping action in the wrist. In that sense it seems a little more "modern" than "next gen"

This is Jack Sock forehand type, where it has 3 check points, when in power position: 1- the racket is parallel to baseline. 2- racket hitting strings facing back fence. 3- racket head is under hand grip, when it is parallel to base line.

Great analysis and agree with most of it. However, in my humble opinion I think that the difference between the side by side stroke analysis is the ball bounce and not the speed. The racket cannot tilt as much when the bounce is high. Your argument would be more compelling if you were comparing the tilt based on the same ball height bounce.

Thanks! I wanted to change to a more sinner like forehand and I also have a pronounced semi western grip. I thought that he had like a semi western to eastern grip so I was trying to change grip. I’ll stop now 😂

we call that lag in the golf world. But also Sinner uncoils pretty hard. Its not only the flip but the combination of both. He is going to be a great player.

can i ask how does the sideways backswing compare to the regular novak upwards backswing where the racket head is also facing the back fence but pointed up. in my head i think, the novak upward backswing will be way effortless and generates more racket speed cause of gravity, but the sinner sideways backswing helps coil for a more momentum on the topspin ball. is that right? or am i mistaken? whats your point of view on this please enlighten me 🙏🏼 cause i dont know which one is better to copy, i can do both 🙃

Excellent analysis. I was always wondering how he hits so hard. Everyone on tour tries to flip the elbow quickly though. Your point on racquet edge pointing towards the opponent is not common - only a few player does it like federer and Delpo. Can you do an analysis of his backhand? I see him matching or surpassing Agassi and Novak's backhand in the future. It's deadly.

How more stress does flipping the racquet place on the wrist and elbow????

I would like to see both examples with the ball at the same height ... unless he allows drop the ball purpose what I doubt

Nice analysis. I honestly believe his elbow is lower here, because he is setting up to hit a very low ball. High balls, that elbow is going to of necessity be higher to accommodate the set up.

Hi, Great analyze, thanks! I am using a Tecnifibre 315 gr t fight xtc racquet and for my tennis class a Yonex vcore 305 gr racquet. I saw that the sinner technic was easily to apply with the 305 gr racquet. Do you think that since technic is more adapted to lighter racquet? Thank for your answer! Patrick from Zoe coaching

Please do on matter berretini Italy

the modern strings and racquets and stroking patterns have utterly completely changed the game (to state the obvious).

Do we see foresee future wrist problems a la Thiem ??

In short he's super-relaxed while hitting. You can place all the emphasis on the racquet tip bla bla bla. The most important point in his forehand is that he's super loose and and relaxed which allows him to whip his shots

Turning the racquet face to the fence like that seems like a lateral raise where you pour at the top of the movement and could put a lot extra stress on the rotator cuff. Even if you are young and flexible does seem like it can eventually cause wear and tear. Djokovic, Federer... etc much better models in my view.

i think the key is the racquet face at contact, before and after for the low ball. There is no pronation. after contact, the racquet tip was not pointing to the opponent but up. It's misleading in the picture. only that way, he make sure to pick up the ball and get it over the net.

Tennis player Sinner is one of those new crop of very talented tennis players who seem unstoppable, until one of the Big Three comes along in another round. In ladies tennis, Miss Iga Swiatek and Miss Naomi Osaka appear unstoppable and invincible, among a few other new ladies players.

Do you have a Nadal forehand analysis video

The thing that seems to not get mentioned so much is that the flip is a passive movement, not an active movement. The flip is created by the legs, hips, core and shoulder, not that much in the forearm other than to guide the power.

it would be interesting to know how his backhand works too

4 bewel grip, the rest is depends on each player partcilulares.

Interesting! I wonder if it's more likely to get wrist injuries playing this way?

Interesting your point about the next-gen tilt eg Kyrgios. I don't like it as a technique. It seems like something people do because they think it looks cool rather than because it occurs naturally or is particularly effective.

very high speed of the racket head but still quite dangerous with time. The stress it demands on his elbow and wrist can lead to injuries over time.

I say wrong if I say that is similar to khachanov forehand? Ciao from Italy

Can you do Richard Gasquet's forehand?

HALLO...GREAT ANALYSIS AT THE RELAXED FH AND THE STRONG ONE THERE ARE DIFFERENCES AT THE CORP COIL AND THE FOOTSTEP...WHAT DO YOU THING?

Rublev also hits low ball forehand with so much power and pace.

Who’s the first one (or first few) started using these type of flip/whip swings? I don’t think Sampras used this kind of swing but I could be wrong.

Do you think they hit off centre on the racket?

Is there a professional tennis player with the last name of Saint? Would love to see a match between a Sinner and a Saint.

One interesting thing I’ve noticed there’s a lot of players don’t caulk their wrists back at the beginning of the motion.Seems like it would take out one step

Do you talk about hip rotation and core rotation in general? Bc that is where he gets his power. That racquet head tip lagging is just a by product of that. Not something he is doing consciously...

Is it really a semi western grip, it seems a full western to me...

The wrist lag (flip) is an effect, not a cause. It isn’t *why* he’s got such power. Same with small guys who hit the ball a long way in golf. They all have exceptional lag. But it’s an outcome of their kinetic chain. It can’t be manufactured by advise such as “keep your wrist relaxed”. Agree with most of the rest of your analysis.

It kinda reminds me of Fognini’s forehand, is that correct?

So his power is mainly from his wrist flick?

This is an amazing analysis, however all those movements are not consciously done, a big thing coaches forget to mention.

Elbow position has to do with grip type. Elbow up: western, elbow down: eastern. Western grip require good timing and strength to drive the ball, raise elbow create momentum from gravity. Basically, don't worry about tip of racket, butt of the racket, elbow and arm position and focus on body rotation.

its 33% are over 90% mph

I taught tennis in a classic area. I taught the Agassi style forehand and within a few years all the teachers in the area were doing the same since classic can not handle the topspin. The "flip" is just a relaxed wrist that allows the racquet face and handle to keep going back as you rotate the hand holding the racquet forward. The face and rest of handle rebounds like a whip and accelerates forward. When I learned it I thought it would just be like the Agassi forehand vs classic. I expected all the kids to learn it and all the WTA players to learn it, and all the teachers to start teaching it. But that has simply not happened. Partly because most teachers do not know how to do it and also because teachers that do realize it is very hard to play well with it. The boost in racquet speed you get from the flip/whip is substantial. However if your timing is not perfect then you will not have the same whip effect and thus racquet speed and your shot will suffer - short or in the net because your 90 percent power swing was only 80 percent and you did not know it. If a kid does learn it and can do well with it then he/she will get pushback from coaches and other teachers they encounter during tournament training sessions. I remember coaches telling my students you should not rotate you will hurt your hips. But in the case of the current ATP forehand I believe it should be left to tennis academies with exceptional students. It is not difficult to do just difficult to play well with it.

I don't know Jason. I think the difference is in court position and foot position. In his first shot, he moving forward on a short ball toward the baseline. He is in a neutral stance, and typically you can generate a lot more pace with the neutral stance because the racket travels a longer swing path. Now in the second shot, he is further back is in a semi-open stance and just wants to hit a rally ball. This is typical of his court position because if he wants to use the neutral stance and try to crush the ball, it will most likely go out. There are many other power advantages with the neutral stance that I don't want to get into but even in my game, I can crush balls with the neutral stance much easier than open or semi-open stances. I don't think Sinner has any technical advantage over other ATP players in general. Most of what separates ATP players is talent in their biological makeup that they are born with and not any advance technique. Trying to dissect tiny technical differences between Sinner and say a player like Federer is not meaningful. Because Sinner's forehand looks a lot like the standard Modern ATP forehand invented by Federer. And I have seen Fed just crush forehands at 100 MPH without any effort at all. Now pointing flaws in the next Gen forehand like Kyrgios is more meaningful.
