You proposed to tighten so that the ball feels the mass of the body. Become a human wall with as rigid arm-racquet structure for contact as possible.And here there is his video about "loose wrist". He says the same what the guy in the first video in this thread. At the beginning the grip cant be completely loose and before the contact with the ball it should be tightened to stabilize the racket. Of course you shouldnt block the movement of the head of the racket in the vertical direction. If you tighten the grip before the contact of the ball with the strings your grip will stay tightened at least to the moment when the head of the racket rises to the level of your left shoulder. As you see it is not throwing the racket at the ball. Nobody proposes tightening all muscles during the stroke.
Nothing has changed. Tigtening the grip helps to sabilize the racket during the impact and we can recover more kinetic energy from the approaching ball. We should seek compomise between the speed of the racket and tightness of the grip because tightening the grip we may slow down the head of the racket. The slower approaching ball is the more we use inertia of the racket so the speed of the racket is then more important but it doesnt mean that the grip is loose. This looseness can be applyed only to possibility of the racket movement upward.You proposed to tighten so that the ball feels the mass of the body.

If you’ve been actually thinking of simply getting some control over RF orientation and not letting it fly away, what are we arguing about? That’s trivial.

What does swingweight mean ? Both my rackets weigh 315 g without strings but additionally they are weighted onto the racket head by a lead strap. About 2 g.What swingweight are your racquets?
Proces of uploading videos on YouTube is the longer the longer uploaded video is. That is why usually my videos last below 5 minutes. I can show you longer video but from 2017 when I used my old two handed forehand. My left hand was over the right hand. I play here with International Champion of Poland in +35 category. I taught him play tennis. Now he is favourite in National Championships in +40 category. I used my old camera so the quality is not good.His theories aside @grzewas seems to hit the ball very well on both wings.
I hope there’s no cherry picking in his videos though. Can you post a video of a whole set you play with all the points, errors included?
Why do you think that when we use muscles we are tense ? Are you tense when you walk or run ?
Swingweight is a measure of MOI with the hand at 10cm from the butt end of the racket. It tell us something about the mass distribution of a racket. It tells us quite a bit more than providing just the mass and the balance point. As a physicist, you should be well acquainted with MOI.What does swingweight mean ?

As @SystemicAnomaly posted. In tennis practice it covers how well racquet reflects the ball power/plows through the ball, given everything else is equal.What does swingweight mean ?

Of course I know what moment of inertia is. To increase moment of inertia I added lead tape to the head of my rackets.Swingweight is a measure of MOI with the hand at 10cm from the butt end of the racket.

Ok, but that still doesn't tell us the swingweight of your rackets. TW measures & publishes the strung swingweight of rackets that are sold on this website. But, since you're adding lead to the head of your rackets, you are altering its swingweight. TWU provides a way of measuring and calculating the SW of your rackets:Of course I know what moment of inertia is. To increase moment of inertia I added lead tape to the head of my rackets.
I am not convinced that the current prevailing method of teaching the forehand (emphasing wrist layback then release) leads to best results. I think this is the downfall of the NextGen at the pro level, as well as the fatal flaw of many a 3.5 player. I think keeping a stable wrist angle through the hitting zone leads to more accuracy.It's difficult to talk/write about tennis form without causing some confusion simply because terms and phrases are not commonly defined/trained. Here goes:
To stay "relaxed" when hitting a forehand really does just mean "use the appropriate muscles at the appropriate time without unnecessary tension elsewhere in your body. Train well enough that this becomes automatic." JMO.
The essence of a contemporary forehand is to generate racquet head speed by getting the hitting hand/racquet back with the body in a fully coiled-back position. One of the points of that posture requires having the hitting upper arm (at first, before forward lauch) well up/out from the body so that there is a degree of locking: left relaxed at the start of forward rotation the hitting upper arm cannot sag farther back if the elbow is high enough. You can relax the arm and shoulder without losing the rotational momentum/speed that the upper body is going to transfer to the hitting upper arm, setting it in motion without any arm flex. The forward swing starts with the flex of muscles, and which ones you take advantage of depends somewhat on your position, preparation. Ideally you extend your legs from the flexed position, which pulls on the leg-to-hip (pelvic arch) pair of muscles and thus pulls your hips into line with your upper legs. This action then pull on the pair (left and right) of hip-to-rib cage muscles (obliques) triggering their contraction, which sets your torso rotating. This sequence is called "uncoiling," and it results from the fact that you flexed your knees and coiled back in the first place stretching the relevant muscles.
Uncoiling launches torso rotation. Your hitting shoulder/upper arm are relaxed and won't sag back, which sag would bleed momentum transfer from the torso to the hitting upper arm. At the instant of first forward motion of the hitting arm you perform ESR, rotating your hitting upper arm in the shoulder socket. This does several things: It gets the racquet back and low, and typically is the moment a player first extends the wrist back, taking advantage of the racquet's momentum backward. (I'm not interested in arguing whether the ESR and wrist extention "just happen" or whether you "do them," though my opinion is that you do them with minor muscle effort until the dual actions become automatic.) The most relevant result of The ESR and wrist extention (usually called, as a pair, "lag") here is this: Once you ESR your hitting upper arm, the new ESR'd orientation of your upper arm takes over the role that getting your hitting upper arm up and away from the side had originally: The ESR'd arm want yield (sag back) as your torso rotation forces the hitting upper arm (and the forearm and racquet...) around. The arm is still relaxed.
Somewhere around the torso hitting 45º from facing the net, your torso is still driving the hitting arm. (This is also true in the serve, typically.) At that point you'll flex the forarm muscles (and the lats...) to bring the still-lagged wrist, and the racquet, around to contact well in front. You want to perform ISR up into contact, the opposite of ESR. You'll find that if you squeeze your grip just up into contact, it will boost the ISR action. That flex won't slow down the racquet (if your wrist was still fully back, lagged) into contact, but will just help intensify the ISR. The ISR accelerates the racquet forward a good bit (so don't do it too soon), causes the racquet to rise in the plane of the stringbed (for spin...), and causes slight forward tilt of the racquet fact (which also boosts spin, provided your racquet face is generally moving low to high).
So be relaxed, except for flexing the muscles needed, and at the correct instant. There, laugh, I'm done.

I disagree that it leads to best results at advanced levels. It works for the Big3, but the generations after them have tried to copy their techniques and failed.Leads to best results at advanced levels. Maybe not the appropriate technique for every level.
When I visited Ecuador last year, the former ATP player that I played against a few times had a forehand technique almost identical to Hewitt. It was the most accurate forehand I’ve ever played against. This guy was only 5’9”, not much of a serve, not especially athletic or fast, but he’d beaten Delpo in an ATP tour match.Ah yes, Hewitt and his famous forehand...

Good enough to make top 300 and stay on tour for 9 years.He was accurate playing at your level, doesn't mean it was a good forehand at ATP level.
Good enough to make top 300 and stay on tour for 9 years.
But the reason he peaked at 300 was not because of his forehand. He was slow, small, unathletic, with a weak backhand and weak serve.Exactly
I would never even suspect that relaxation of jaws is so important in modern tennis.
Yes.
Now you know, as this video was posted by Gregory Diamond in 2018
Do you suggest that I am Gregory Diamond ? I didnt know. That would explain why his Youtube channel is the same as mineNow you know, as this video was posted by Gregory Diamond in 2018
Theres nothing wrong with Greg's mouth. The most relaxed muscle on this forum...[emoji16]Keeping the jaws loose is important in any sports including tennis, it is an indicator that will show if you are tight....
I had you figured from the first post GD.Do you suggest that I am Gregory Diamond ? I didnt know. That would explain why his Youtube channel is the same as mine

To be honest I wasnt sure whether Seles was having a laugh but then your unique communication style gave it away!Why didnt you tell me ? I would know who I am from the beginning.
I listen but I tested almost all techniques. I just know answers. That is why I have won so many tournaments.
Today when I was playing tennis I tried not to clench my jaws and tried to hit backhand with loose grip. No power and no control. I dont like to lose so I tightened the grip and won 6:3 6:1To be honest I wasnt sure whether Seles was having a laugh but then your unique communication style gave it away!

Who were you playing? The win is only relevant to the standard of opposition - and trying to stay relaxed after years of stiff jerky pushing may take months to get out of the system. Also, winning using poor technique does nothing but provide a false sense of security and offers no incentive to improve. You have repeatedly drilled home how your style has got you so far but never quite to where you want to be - champion of Poland in the whatever age category you now compete in. I know you'll disagree or repeat some of your dogma, but try some of these recommendations seriously and you will get some benefits. Its not your muscles that are tight and unbending, its your mindset.Today when I was playing tennis I tried not to clench my jaws and tried to hit backhand with loose grip. No power and no control.

I practiced long rallies before my first match in Polish Championships. I will play against one of two major favourites. He was Polish Champion in doubles when he was a professional.Who were you playing?

You have to do more on that return of serve against the low pace in the video. I get going down the middle deep of a good fast first but those are two very slow seconds.I practiced long rallies before my first match in Polish Championships.

The tighter my grip was the better I played.
I didnt want to attack his serve because I wanted to practice long rallies. That is my tactics for the first match in Polish Championships. I play against former professional. Polish Champion in doubles(as a professional) and runner-up in last year Polish Championships in +50 category. The only chance for me is to tire him so that he began to hate tennis. Usually his matches are short. He's not used to playing too long matches.You have to do more on that return of serve against the low pace in the video.

Edit: did you relax your jaw or tuck it in behind your elbow?
I join the 50+ next year so will be looking at playing a few tournaments work permitting - thats a big caveat. The UK is very strong in this category so will be looking to play more singles tournaments to beef up that mental sharpness.I didnt want to attack his serve because I wanted to practice long rallies.

Not the player in this video but my opponent in the second round of Polish Championships.... at something other than tennis.
