제가 사용하는 라켓은 325g입니다. 라켓 무게는 적당한 것이 좋은데... 너무 무거우면 손에 긴장을 계속 유지시킵니다. 적당히 무거운 것이 좋습니다. 따로 레슨은 하지 않고 두달마다 한번씩 오프라인모임을 경북 군위 또는 대전에서 하고 있습니다. 시간되시면 한번 나오세요.
You might be basically (or ideally) correct in your fundamental analysis. But it is incomplete and misses some crucial aspects and details as regards Federer's forehand swing. First, it is precisely Roger and nobody else who does take care not to over-rotate in any of his swings and thus his hips and torso rotation come to a halt before the contact point. Thus, Fed's swing Is - yes - relaxed and balanced (and based on the "whole body rotation" in this sense) but it does not happen as a single unit.Roger never rotates from the lower body at the moment his racquet strings meet the ball. You ignore the conservation laws in your analysis and don't consider the dynamics of a whip in any relevant detail. Secondly, an implication of the previous point, you dismiss Roger's trade-mark footwork employed in a stationary enough open/semi-open stance baseline rally swing, that is the *back foot pivot*. There is certain irony and a solid teaching here to be discerned that whilst Roger's swing is balanced and fluid rotating around the spine he nevertheless is more pedantic than anybody about not rotating around from his lower body thus managing to freeze the previous kinematic chain preceding the contact. Thus, it is Roger who you see swinging his forehands pivoting on his rear foot more frequently than any other ATP player.
Thank you for your comment. My theory is to give players a bigger swing radius and a way to use their hands and forearms like a whip. Of course, it can't be the same as the Federer swing. However, it can be implemented almost similarly. Give me and my disciples time. In a year or so... you'll see just how much better they swing as amateurs.
@@jultennisgolf4970 Yup. Great, even ground-breaking work & workable methodology. The Chinook posture - clever! I enjoy watchng your videos and they have widened my scope and deepened my view about Fed forehand also. The stretch reflex for example is an interesting notion. Roger - does he rely on that - he says he goes from "1" to "2" in grip firmness just prior contact (and then back to "1" after It) implying he does not (not completely to say the least); 1 = completely loose grip - 10 = rock hard grip). Keep on training and uploading these eccellent videos, Kim! ;-D Thank you.
@@jultennisgolf4970 but it's not similar at all, you're basically teaching yourself how to do it exactly wrong, your left hand is flinging into overrotation and as you yourself pointed out the crucial thing is SIR, exactly the thing you're using with over rotation you get zero shoulder internal motion..
I absolutely understand that concept. Great to watch both of you - but this guy does not feel this concept. He is trying so hard with his arm. And that tension kills that idea. Hope to se an update from this guy. Thank you so much for sharing this great video Greetings from Austria
probably the most underrated video of Tennis instruction on RUclips. Never learned so much. Thanks for putting this together!
영상작업하느라 고생하셨습니다~
무사도님, 뜬구름님 포핸드 엄청나네요^^
두분 모두 거의 완성단계로 진입하셨군요~
축하드립니다^^
영상잘봤습니다
2013년도 레슨받을때 어깨가 먼저열리면안된다고 하도 그래서 힘들었는데..몸통회전을 하게되면 왼어깨쪽..몸통이 돌아버리는거네요..설명이 시원하십니다..레슨장소가 어디세요?ㅎ
그리구 라켓은 제가 프로스태프 315그램쓰고있어요....교수님께서는 무얼쓰니나요?...몸통회전으로 치게되믄 무거운것도 수월할듯해요.!!
코치들도 이동영상을보고 반성했으면 하네요..팔로만 쳐왔으니..
무거운라켓이 힘들죠...체력이 떨어지면은...

네알겠습니다..그리구 저는 무거운 라켓이 좋아요..주변에서 쉬운라켓으로치라고 하도 그래서 생각중에 있지요...답장감사합니다

Federer also doesn't pull back both arms as he teaches here, there is no chinook pose.
It‘s perfect ! that is what I want to say!
I absolutely understand that concept.
Great to watch both of you - but this guy does not feel this concept. He is trying so hard with his arm.
And that tension kills that idea.

Don't turn your head away from the ball... That's the opposite of what rog dies..
