You think it's rocket science, don't you?! Once again we're talking about the basics of his motion, right?
 
Your temper tantrum of righteousness is noted. You are absolutely 100% self-righteous. A pig name caller using lair and integrity while you

has been on this boards for quite awhile asking questions and improving his game trying the suggestions he has been given. He has posted

If you went to college, it is obvious you failed to learn how to treat others. Dale Carnigie wrote a book on the subject "How to make friends

The fact that you have no provided evidence for your claims says nothing about what I think about how difficult it is to imitate Federer's forehand.

I say you need to back up your claims. You say that me thinking you need to back up your claims = me thinking the forehand is rocket science.

I say the two things are in no way connected.


Now you're playing make-believe about what I think. Did you never learn that Santa isn't real?

I haven't called anyone names. I have only described the categories that people's actions place them within. You actually are the first in the thread to call names by calling me a 'pig'. I love me some hypocrisy in the early morning hours. Delicious and nutritious.

All I've done is tell people what their actions say about them.

Making claims and failing to provide evidence? That means you lack intellectual integrity.

Lying on the internet? That makes you dishonest.

Condemning a person for an action that you yourself commit? That makes you a hypocrite.

Attempting character assassination over technical disagreements? That means you're insecure.

Derailing conversation and making personal attacks rather than discussing the topic? That makes you a troll.



It's pretty obvious here who's actually throwing the temper tantrum. I'll give you a hint: it's the guy calling people pigs, the guy playing the classic "you wouldn't say that to my face" internet toughguy routine.

Now there's some courage!

I wanna see a Federer forehand, and spread-eagle-era Gulbis forehand.

You will have my respect just for attempting. Doesn't even need to be 'correct'.

Courage? I have shown many times before I have no problem posting videos.
Anyway, here you go. Nice and simple. I hear some folks need to spend 10 years to figure this out!!
Reminder: we are talking about Fed's basic motion, don't make silly comments about how it's not remotely identical!!
Next Gulbis fh but I need to study that a little.;)

As idiots I would define 3.0 players who think they know everything about tennis. Watching their movies is the easiest way to verify their real skills and knowledge.
 
Curious said:
Anyway I can copy Fed's fh or Nadal's or Serena's, or anyone else's. But the stupidity is that people would say 'oh your right arm doesnt quite move like it, your head is 10 degrees more deviated to the right' and so on as if it has to be identical!! Can you walk exactly the same way as another person? No. And there is no reason to do that. Again the basics of their forehands are not rocket science and no sane person would need to spend 10 years to figure this out! That's my point.

My point is that you are an arrogant dilettante and do not understand the physical and biomechanical principles of human motion sequences. The movie above is a beautiful example. A guy who doesn't know how to hold the racquet defines new standards for Federer, Nadal or Serena. Rofl.

Show me Federer forehand. I want to verify your competence.

Calm down mr genius! Video already posted above.
 
Curious said:
Hmmm so you have nothing to say whether the basics of the motion are the same or not, which we were talking about, which took 10 years for you to grasp!

Do you want a serious comment? It's simple: you have no idea what you are talking about. Your motion has nothing in common with Federer forehand. You do not understand this sequence. You can't even control the plane of the racquet head and your finish is a pure chaos, what is a clear indication that you try to actively (and desperately) recreate the external form of a motion sequence. From the side, this stroke would be awful. With the ball, it would be even more horrible.

I can also say that your self-esteem is inversely proportional to your real skills.

So, to clarify:

1.) You claim to be able to identify and copy the basic fundamentals of any top forehand

2.) You claim to know how people will respond to a video demonstrating said forehand

3.) You will not post a video because you claim to already know how people will respond

4.) You have provided no evidence for your claims



There's a phrase for what you're doing.

It's called 'making **** up' also known as 'dishonesty'

Dishonesty is usually a byproduct of shame and insecurity, or it's a response to abuse. There's no abuse here... so it follows...


Food for thought:

Maybe if you stopped lying on the internet you wouldn't be so insecure and ashamed of yourself?

Millions of people wanted to copy Federer forehand. Everyone failed, except me. What's more important, I was able to create a solid scientific model for this stroke and use the same physical and biomechanical principles to create topspin backhand. Federer didn't do that, man. So, I definitely have no reason to be ashamed.

I am still waiting for your "Federer forehands" - with the ball, from the side and fully controlled. Don't be shy.

are you saying "half inertial" because while the arm might be loose (ie. the string&bead attached to the drum), non-pro folks typically have a still wrist, and don't allow "lag & snap" to happen?

i'm interpretting his idea of "copy" as referencing the "style" of a player's stroke (or perhaps even just the grip)... not the actual quality (ie. the firing and sequencing of the various points in the k-chain) - because if he was doing all that, he'd be pro.

Inertial serves will be presented after the publication of the book. I am tired of stereotypical behaviours of people, I do not want to read all those "professional" comments of incompetent arrogants.

Please check my experiments with the chain in the movie above. The first example is what I call half-inertial. The second one is inertial in every aspect.
 
jch is pretty bonkers...

But that being said, that forehand is not even close to Fed @Curious

You push the racquet back too much with the tip pointing up,if u check fed he barely does a bit, you have a bent arm not a straight arm, and your grip is wrong.

If you fix these things and make another vid im sure it would look much more similar.

Yeah, pretty close. In a nutshell eastern fh grip, wrist extended during the take back with racket head up, gravity pulling the racket down to the 'pat the dog' position racket face now parallel to the ground and from there leg drive+torso rotation with a loose wrist and grip resulting in the racket flip then catching up to contact. That's about it. But this guy wants to associate it with quantum physics because he spent bloody 10 years to figure it out!

Do you really think your forehand is a copy of Federer? Because going off your videos it looks nothing like it at all haha. All you are doing is a typical ATP forehand without a proper unit turn, next to no torso rotation, and you are dramatically overexaggerating the wrist lag to an unnatural level. How you have not injured your wrist is a mystery to me. Also you seem to alternate between straight arm (ala Federer) and a bent arm as well. You should let the wrist lag naturally happen by moving the forearm foreward, not actually forcing the wrist back. Your video on the first page is proof of this. There is barely any torso rotation as well, and your non-hitting arm just stays clenched to your chest most of the time. It's almost as if you are arming the ball over. If I was to say your forehand was a copy of anyone from an aesthetic standpoint, it would probably be Hyeon Chung.

 
jch said:
Conservation laws work always and everywhere, so they are present in the physics of the monkey drum, too. There are phases of the motion of the md, where they are clearly visible, but generally, this motion is dominated by inertia that doesn't affect the work of conservation laws.
Click to expand...

I'm just a layman with regards to physics. You said there are phases of the monkey drum where there is inertial motion.

1) My question is how do you make the monkey drum 100% inertial. Is is possible?

2) How does that translate to a tennis stroke comparing one that is completely inertial vs. one that is not. What is physically done differently by the player to make it 100% inertial?

That looks more similar to his forehand indeed.

Tho he is still overexagerating the lag muuuuch much more than chung.

in general i do like jch stuff... would have been useful to me say 10-15y ago when i was trying to define the idea of "lag and snap" in my own head... but seems like you guys are arguing 2 sides of the same coin.
 
The ATP forehand, and it's various iterations, are difficult to master for the non-professional. Casual players would be much better off learning the WTA style forehand, or even a more classical linear forehand with an eastern grip... or continental if you never play on court surfaces which promote spin above shoulder height. There is just so much less to go wrong with these other styles, they are much easier to learn. Yeah you sacrifice net clearance and maximum topspin potential but most amateurs would benefit from consistency and accuracy far more than they would from cranking 3000rpm.

Take this clip of Edberg practicing with Fed. Mastering a forehand like this is 100 times easier and more suitable to 9/10 amateur situations.



Or everyone can spend their time trying to master this, and only ever get half as consistent.

Good analysis alltho Federer uses a slightly modified eastern grip and also he doesnt always reach pat the dog parallel position...

See this vid:


1st forehand is quite close to parallel, now if u look at a few others like 0:48 one its not even close to parallel when he initiates the stroke.

Thats why I always find this so ridicilous when people copy a stroke from a pro to every little detail and claim they hit like them....when its not like that for pro players.

For pro players all these lag, pat the dog, pronation, swing finish...whatever.. are the result of a swing/stroke they want to hit, they dont actively pursue these "checkpoints" but they happen as a result and they dont always happen the same because it depends on the ball, contact point, stroke they want to hit etc..
The only things that ideally always remain are fundamentals, leg drive etc..

I already said that it was not and doesnt need to be the exact copy of Fed's motion but the basics/mechanics are the same as I described all the crucial features in my last post above. I'm not surprised to get this comment from you though as you want to copy everything he does.

I don't hit a Federer style forehand so not much comparison for you. Mine is pretty simple, closer to that video of Edberg I posted just now.

It's funny how you are deflecting my arguement by asking for video footage rather than actually addressing my comments..

What question did I ask? Are you confusing me for another poster?

I came across your youtube a while ago. Going off your comments on this forum jch you really do come across as incredibly arrogant and narcisstic and seems to match your obsession with displaying what you perceive as the most amazing and revolutionary tennis discovery of the last decade. Your style of hitting a forehand is a recipe for wrist injury and I hope no one tries to copy it.

edit: And I don't have any videos of me because I don't need the approval of weirdos on the internet to validate my self worth :)

I looked closely at your bh in videos and have a question (yeah, in a FH thread, since you haven't started your inertial one yet). You make a FH-like flip, I guess, with taking the racquet back initially with handle closer to the body plane than tip. Then it rotates 180 deg before forward swing. However, for FH, yours, Fed's or any other ATP-stroke player, the flip "takes place" once torso rotation starts pulling the arm pulling the handle. On BH side you flip over your racquet before torso rotation and arm being pulled forward. Why you think it's effective to flip the racquet such a way with your arms?
 
All this discussion aside, I believe I have matured tennis-wise and moved on to other things than trying to copy anyone. I know the fundamentals of every stroke in tennis (basics ) and try to stick to them, hitting my own strokes now. Other things interest me much more like, placement, game plan, serve and volley, fitness. I'm the only one who serve and volley in my club and for the first time I did that while playing doubles on every single serve for 3 hours and absolutely loved it.

OK. First, I am not arrogant. I spent a lot of time doing many things and I try to share my knowledge between people who do not know this knowledge, do not have advanced tennis skills, but perfectly know how to talk disrespectfully to others.

Second, your analysis of the role of my wrist is so comically wrong, that I will put it in my signature. Time will show your competence better that your movies.

I can't even deal! Please explain to me how your wrist flicking like that is a natural and unforced motion. Have you even considered the ramifications of promoting such a ridiculous technique as being a scientifically proven and safe technique? You are a hack. Feel free to go into as much depth as you like, I am a physics and maths teacher so I will be able to follow on quite easily. Tell me how it is "inertial" :D

Really good question. The answer is simple, the technical explanation - not. Please ask me this question in a few months, after the presentation of the background of inertial tennis. Personally I think that you won't ask, because then the answer will be obvious for you :)

You know, I don't intend to hurt you again, but I frankly find it odd how you came up here with your ideas to only tell that it will be available in 3 months and all our questions will be addressed then. It could be some pre-marketing, but since you claim it to be a concept rather than an explicit teaching metodology (you told earlier it's up to coaches to get kids - and amateurs are the same - understand it), I don't believe you're after earning a fortune by selling your books to tennis crowd. I trust you really have that thing in your pocket which you won't show anyone until right time comes, but cmon, what you expect? You've been told "yeah nice strokes" based on video - but why should everyone accept your concept superiority? No replies required actually for this, if you are not ready to develop the discussion yet - let it be.

Thats not really true, its true he is the model for my strokes but I dont copy his whole stroke and motion but try to make it so its the most natural and comfortable for me, thats why there are some differences with his serve and mine or my fh and his or my bh and his.

The answer = your theory is fake and based on nothing but the aesthetic subtleties because you can't explain it to any sceptics using actual science.
