Good video.
What he is talking about called timing.
Timing wrist with the rest of kinetic chain.
But there is not much of the forearm muscles action. It is purely timing wrist with legs.
And yes he is right saying the kinetic chain learning should be started with the wrist. No wrist no kinetic chain.

How can I like him if he says "Now I literally move just my wrist..." and then demonstrate this:

Funny stuff, when a guy demonstrates live and is unaware what exactly happens, it's understandable. But when he films himself and publishes a video... cmon

Great video.
Feel the weight of the racket head!!!
A guaranteed way to get rid of muscle tension and stay loose.

Wish some of the "big muscle" pundits around here would watch. And the 2 handed Polish guy needs to watch this and there is a part where he shows the concept of MgRi without stating it (where he is swinging like a golf club).

Well done


Hey, those are the courts where I usually play! I have seen many coaches there but not this gentleman. He has great insight, but sorry folks, I will have to quickly forget what I saw, lol! I am just beginning to appreciate the joys of being very relaxed and loose, and don't want to start muscling the ball with my forearm.

This guy is a hack. Most of what he says is total bs, and he periodically blind squirrels onto a nugget of truth.

Weird man. Stalk him and find out. I dont think he is saying to muscle or to stop being loose.

I will keep an eye out for him. I got the impression that he was emphasizing using the small muscles of the forearm consciously to generate racket speed, which would involve too much retraining for me because I make the whole arm go limp during the stroke (at least, that is my intention). By the time I get the timing with his method, my wife will have confiscated my tennis equipment and limited my exercise regime to just walking with her... ha ha!

Hack. Try using only your wrist on the run hitting 5 balls at pace at a advanced tennis level. Say 5.0 . The reason the coaches stress big muscles kinetic chain is to be able to move fast, stop, and hit properly with a repeatable contact point.

But yes there is elements of wrist in any shot. It is part of our arm after all.

MgRi huh? Have not seen this term prior to this.
Racket physics? Is this what you're talking about?

Yes this looks funny but his video on Cracking The Whip is very good and his interview with a Stanford player on how he became great without home schooling and going to a academy is amazing.

We can always find some little bit we don't agree with, esp in tennis.
 
Some movements look like wrist movements and are rotations of the forearm and arm, although it is not totally pure and the wrist will be less laid back at contact than at max lag.

I believe most of the wrist movements are arm rotations but I also don't believe into those extreme robot models that say the legs and trunk rotates and everything else is just elastic energy.

A lot is elastic energy but if it was 100% passive you could just tell a beginner to rotate his body, relax his arm and his mechanics are going to be fine.

Sure a lot is elastic energy but there are also some well timed active contractions needed to control the stroke but this doesn't mean you muscle the racket with the arm.

^ Yup. Much of what coaches and TV tennis commentators attribute to the wrist are really pronations & supinations of the forearm. These are not articulations of the wrist -- at all. It's the muscles of the forearm are turning the hand. The wrist can be flexed, extended or (radial &ulnar) deviated but it is not responsible for turning the hand.

Exactly, in a good stroke you use lots of smaller muscles to control timing and channelling of power produced by big muscles, as well as set up your body before major power generation phases.

That’s quite legit, and I also think one can learn from what he demonstrates, but not from what he says. The key issue I see is possible when a player tries to bump up the power: if he’s convinced to “use” his wrist, he’s likely to do wrong stuff to get more power. If he’s instructed to use leg push and torso rotation while keeping loose/smooth wrist action to time and channel that power for the right moment via flip (lag and release), he has chances to succeed.

To the extent that tennis strokes are similar to throws (or similar to underarm pitches as in softball for the forehand), one can consider how much and what the body & shoulder contribute versus the wrist. By being limp (except maybe for an initial/unconscious activation to get things going), the wrist just absorbs the power from the body, and the associated muscles should just get out of the way lest they slow things down... at least, that is my "working" model now. I know it is more complex because the small muscles kick in for control and stabilization, but luckily all of it happens without us having to "think it out."

You don’t consciously control your movements to a high or low level. You train the movement. The swing happens too fast for you to fire a muscle a ‘x’ moment for something to happen.

Your brain trains the sequence that you consciously and unconsciously put in there but you don’t control it. and when you throw a ball your conscious mind knows what it is supposed to look like and your brain self corrects as you go and repeat.

You may select the shot to fire, you may influence the calculation through thought but you’re on muscle memory most of the shot. That’s why shadow swings and progressions are important training and habit breaking tools

I wouldn't have thought it possible to fit that much wrong instruction in 16 minutes.

When he was showing how much power he could generate on put away balls and was being fed mid court sitters and they were bouncing twice before the fence, that should be a clue that whatever you are doing isn't working.

Dude basically said I can relate to you guys because I can't play tennis either.

You mean like voting for the guy you would rather have a beer with? In my analogy here ... are you an irritating elite or a skilled surgeon?

Its a fair point. He is not a tennis god but did you see kyrios in that vid? I think there is something to that small muscle thing and you can hear in the vid the ball tags the fence off the bounce.

1st off this is some hack who mowed his back yard and hand drew lines on the ground. Probably lifted the net from the public courts.

Did you see the kyrigios fh in that vid. iT was NOT The normal fh. It was his "I wish I could hit like j011y and here is my attempt" fh. Was a rocket.

BBP,

Are you so bored and so good with tennis craps that you have to entertain yourself with other things?


Me too. LOL



How the phukkkk do folks constantly find technical things to talk about? :) It's the same stupid ground strokes, server and volley that they been doing for years, no?

I am a bit anal/funny phukkkker bipolar ... hence the range between lame ot jokes and the 12 reasons a hand might move in a tennis stroke.
