Daryl,
Ground forces need to be trained and can't be applied physically, time the message gets from the brain to the feet the golf swing motion has been executed.
Essentially should be applied the first move in the downswing.
We played with the idea of try this physical and measured ourselves and tons of others doesn't work needs to be trained.

Daryl I may up set a few people here. Has a Golf coach ever studied biomecahnics or how human body works in the golfswing.
No.
So they don't know how to teach how the hips are suppose to move effectively.
Truth is they are going on their belief system of how they think the pivot works.
I appologise here I'm a straight shooter and speak the truth.

force vs. counterforce
 

You will get it immediately by making a swing on a rotary chair, which disconnects the ground to your feet.

Cause vs.Effect
 

The body reacts (Action) to what the brain orders (Intention) and moves the club and the ball, regardless of if you know the process.

You eat and the body takes care the rest, during which there is not much you can do about it.

Eat it right and you get healthy. Give the right order and you get happy result.

From what I've read on the WWW, and viewed on You-Tube (search: Golf Biomechanics) it seems that ground forces are used to restrict the Feet, knees and Hips so that the Torso provides much of the Rotational motion necessary to provide Power/Speed. No axis tilt, X Factor, Shoulders lead the Hips post Impact.

Example: http://www.youtube.com/watch?v=QO6x8... A2FA4&index=0

It also seems that none of the researchers have classic golf swing training and I doubt that any of them have heard of TGM. The researchers are soccer players.

There are a handful of very accomplished players you'll find under the Topic of Biomechanics, but it seems that they're being studied or have modified components to their Swing. Otherwise there aren't explanations of-what they're doing different than before or how they benefit.

The more I research the more it seems as if people study the Golf Swing to get their "Degree" in Biomechanics rather than actually contributing to Golf Mechanics. Most seem to be using Biometric Terminology to explain why some players can hit the ball farther than other players. What is obviously and painfully lacking is the mention of "Scoring". Golf is still about scoring, isn't it?

Another painfully obvious observation is the lack of any research methodology that can produce useful results. For example, some compare the Downstrokes of various Golfers to determine the point of maximum speed in the Downswing. The golfer with the Highest speed closer to the ball wins. Correlations between Shoulder Speed and Clubhead Speed are compared and the Winner of the test is said to have had a more optimal Shoulder turn. Garbage. But, collect your Diploma and get out of the way for the next class of Biomechanic Graduates.

Oh, and the new Term: NeuroMechanics and NeuroMechanic Reprogramming. I can't wait. :) Pass Universal Healthcare, then wait in line for "Neuromechanical reprogramming" before your next scheduled Tee-Time.

I guess that all of our golf swings fall under the Study of human motion and Biomechanics. I kind of get the feeling that we're all being reclassified and categorized "Biomechanics: Golf Swing" as opposed to "Biomechanics: Tennis Swing". :) So, I'm a "Biomechanical Golfer".

Bioengine must swing very different than those I've witnessed during my admittedly short investigation.

I wonder if his long TGM training and understanding of Golf Mechanics ("Geometry and Physics", or "Alignments and Work") have somehow adapted some of the Biometrics recommended motion to fit his own way of swinging?

Is there a Video of "BioEngine's" Swing we can study? Until I see that swing, for me anyway, further conversation about BioMechanics is a waste of time. "Show me the Money".

My NUMBER ONE question to any biomechanic type would be . . . . do they understand how the club works . . . . if they don't understand the face and the plane . . . . no need to talk about it. If you ain't got a grasp of the 3 functions and the line of compression . . . all the motion stuff can be compromised in it's ultimate objective in my opinion. You still gotta start with the clubface and ball and work the components from there.

Of course that being said . . . plenty of people have got really good based on some goofball pga manual instruction . . . .so who knows.

Sounds a little like what TGM as a company was trying to accomplish with the Bio-Mechanical manuals. Good stuff for physicians who understand the golf swing. It all has to start with the little yellow book or they've got nada. Just my opinion.

Kevin

What does Homer base his work on Newton's Laws.
In Golf Biomechanics we apply Newton's Laws.
Homer talks in mecahanical aspects in hinges and levers, coming from an engineering back ground. Homer has great information.
Homer has theories and very good theories, although he doesn't tell you application or how to train or how to make the theories work in practice.
So how do you teach TGM and how do you apply it?
In order for geometry work you need physics.
A plane can't fly without an engine.

Sure there are biomechanic companies which just do pure research.

There are also others which look at how movement patterns work and research ways to build programs how to train the body how to create correct movement patterns.

Ok how do you expect someone to get on plane and achieve a flat left wrist if they have a huge lateral slide. Club can't move on plane if it has no axis to move around,Homer says a pivot.
Which is your body.
If your arms are decelerating due to the lateral slide.
How do you prevent them from breaking down and scoping.
Teach them plane line and educate hands? when you have no pivot.(your body)
Or how about simply teach them how to create better lower body mechanics.
Create ground forces and hip rotation so they get rid of the lateral slide. Then they have a pivot,then you can get the club on plane and achieve a flat left wrist.

Here's my question how can you teach someone golf when you don't understand how the human body functions. how your body moves, how your body creates speed, how the muscles work and what your body limitations are so you don't get injuries and so you don't teach people to move your body in ways it's not designed to.

My question is how can you apply homers work. The Pivot(human Body) is the foundation of homers work. So how can you apply homers work when you don't understand how the human body (PIVOT) works.
Good luck, I'd been around TGM all my life and taught TGM as well. I soon learn the that we need a pivot.
I hope one day you all come to realize this as well for the better of the game we all love. The Game of Golf

Good luck to you as well bioengine. With your passion you will be very successful.

Kevin

OK so a couple of things here . . . .

1. I'd say the first piece again is how the club works. There are plenty of people with crappy pivots that can still play golf because instinctively they know how the face and the club works. But I will agree with you that a functioning pivot certainly is important.

2. Sure we want to understand something about how the body works agreed. So let us define a few parameters to again focus the discussion. How much slide? How much turn? And we talk about that . . . in relation to what? The ball? Also . . . . what plane? The plane angle requires different components in the pivot wouldn't you say? Is there an "optimum" plane from a biomechanics standpoint? What type of shot are you trying to hit? Does that have different pivot requirements?

Bucket,
I will get back to you on this, I spent sometime replying to your questions and the site crashed on me.
on a quick note golf is a dynamic and power ballistic sport.
One think I do disagree on is positions and angles. I see other companies speak about the hips being open x amount of degrees etc.
Yeah great thats going to help us, for example one mob beleive the hips are 40 degress at impact, Great so how do you get your hips to be 40 degress at impact??? how do we know where 40 degress is in space.

What's important is how to train the body to create effective movement patterns and dynamics so we create good position and angles.

I will answer your questions further in the next few days.

Thanks I look forward to your reply . . . . I don't disagree with the angles piece necessarily . . . However, I think if you look at swings like Snead vs. Hogan vs. Nelson vs. Jack vs. Palmer vs. Buck they all had very dynamic but very different pivots and sequencing . . . much to do with different ball flights . . . the pivot can have MAJOR implications on launch conditions via differences in the angle of approach and angle of attack.













That being said there are probably common demoninators as well . . .

Good discussion . . . thanks for putting the time in.

Bucket,
Due to privacy agreements with tour players, I can't mention names.
Over the years the boys have provided evaluations to at least 4 former number 1 players in the world over the years.
Interesting enough.
They all had 6-M-1 starting form the ground. This was measured.
They all had an awesome kinetic link (6-M-1).
at impact their hips were open between 20 to 25 degrees.
Hips and shoulders were perpendicular to their spine at impact. So hips and shoulder were square to each other at impact.
With minimal right lateral bending.
Then all had good muscular loading. Fire and load muscle in right sequence in swing.
The way they fired their body in sequence was all very similar.
All had ground forces and stable lower body mechanics, which stabilized at impact, actually their hip counter torque at impact.
Once the upper body was square to their hips at impact and club was released the hips and shoulder turned to finish position as together as one.

Like all these guys above appear to be similar.

This is what is interesting, their geometry all looked different,
even though their physics was the same, they created similar movement patterns. One thing which was the same is their sequence or kinetic link to start the downswing were the same. ( 6-M-1)

Although their plane work around the axis of their spine.

Is interesting even though their physics were identical their geometry appeared different. There swing all looked unique and different to each other.
I thinks it's pretty cool.
Primarily we focus on is creating the right physics and movement patterns. Then create training programs for each person so they can develop effective movement patterns.
Basically what we do is screen a golfers to measure their movement patterns, then create a program to improve movement patterns to create the right physics and develop a kineticlink (6-M-1

Very good . . . . so focusing on the similarities exclusive of geometry (which I think is significant at least to the curvature of the ball) . . . .

I highlighted some of what you mentioned in terms of similarities . . .

1. When you say the hips and shoulders are perpendicular to the spine . . . .what do you mean there?

2. As far as the hips and shoulders, was the center of the hip turn in front of the center of the shoulder turn? If so how much?

3. When you say the hips and shoulders were square . . . you mean open the same amount?

4. Minimal lateral bending . . . is that bending to the right with the spine?

5. Could you elaborate on muscle loading?

As to geometry, to me the geometry differences are very significant maybe not interms of generating speed BUT almost everything interms of determing trajectory, start line and curvature. If you consider the differences in grip type and where the arms of the players I posted are in relation to the ball the release motions are vastly different. These players all hit vastly different "stock" shots as well as a result of the different launch conditions produced by their respective geometry.

No question the ball responds to speed generated by the similarities you mentioned that you have studied. But it also responds to the particular face path angle of attack, angle of approach and ascent produced by the different geometries.

But I'm very interested in similarities that you have found.

Learning Center
 

Great stuff, guys.

Listening!

:salut:

Yeah ball flight will be different everyone compresses the ball different so they are going to create different spin rates and ball flights. Another factor is also club fitting kick points,shaft flex and lofts etc.

Q1 Ok picture this T the horizontal line represents the shoulders and vertical live represents the spine.
For the hips turn the T up side down again horizontal line are hips and vertical are spine. Hips and shoulder are perpendicular to the spine.

Q2 Hips aren't in front at all at impact. They are square to each other at impact. On 2D video cause sometimes true impact is in between frames. 2D can't pick this up at all. You need to be able to measure ball collision and body rotational speeds to gather this information. But when measured this is what occurs. Down side of 2d video can't measure speed or movement patterns.

Q3 Yeah that's right on good player or people who have good movement patterns between 20 to 25 degrees open left of target line. The hips and shoulders are open the same (square) belt buckle and sternum are in line.

Q4 Minimal lateral bending is your tilt or bending to right at impact, very important this stabilizes at impact doesn't continue to lateral bend. The straighter spine better the rotation and better transfer of speed to next body segment.

Q5 Muscular loading is loading and firing muscles groups in the golf swing. There are two things which drive 6-M-1
Conservation of momentum and muscular loading. Muscular loading power of fires conservation of momentum in each body segment.

We measure the muscles loading and firing in the golfswing.
We measure how effectively you loaded them and how well you fire your muscles.We look at if you loaded and fired your muscle groups in the right sequence and if you fired them at the right time.

We teach people how to train there body to create conservation of momentum and how to load and fire their muscles. through training they learn how to do this naturally when they play..

myself I have 6-M-1, conservation of momentum, I know how to load and fire my muscles right. I can have my hips and shoulders square at impact, my hips and shoulders are perpendicular to my spine. This why my back doesn't hurt.
I call compress the golf ball pretty good and very well known for my striking abilities.

Interesting stuff . . . . . In your training exercise . . . . are the "golfy"? Do they mimic a "golf like" pivot? Or do you work on the separate components lateral, vertical and rotary separate?

thanks.

B

Bioengine,

Regarding the hips and shoulders being open the same amount at impact I have a ques. Does this then mean that the hips need to turn more in the back swing than x-factor type instruction tells us? Or are the shoulders and hips matching up at impact as a result of the shoulders catching up to the hips?

They come in handy!
 

Bioengine,

I agree that the pivot is very important. Zone 1 is where people should start BUT you cannot feel # 3 PP (clubhead) , trace the plane line (shaft/sweetspot plane) as well as execute one of three hinge actions (club face)on command with the pivot. The pivot does all the heavy lifting the dumb brute if you will. The hands are the command post, and without the science of relationship (Geometry) a golfer will have nothing but a dumb brute pivot with moron mittens! Hell, before reading Chapter five of TGM I did not even know how to grip the club properly. I have played pretty good golf for 20 years now. No amount of physics can teach you to put your hands on the club correctly. I do not think a chasm exists between action and motion, as you seem to suggest. Designating a percentile participation score seems silly.

biomechanics
 

Bucket,
We focus on two things with the hips ,creating hip rotational speed and stabilizing the lower body at impact.
The hips are designed to rotate perpendicular to the spine. In tennis, baseball and golf the hip rotation is the same.In all three sports the body have similar movement patterns and create body segments speeds the same. The kinetic link is the same. They all use 6-m-1 starting from the ground up, the two factors which drive 6-M-1 is Conservation of momentum and muscular loading.

6-m-1 is how the body wants to naturally move and naturally transfers speed from one segment to another and finally transfered to the club or bat.Muscular loading is the engine which creates the speed in each body segment.

We use all types of techniques to train movement patterns and depends on the data to what type of training we provide to each athlete. Every athlete is different and has different movement issues. So once we measure their movement patterns then we devise a program for that athlete.
We don't teach people on practice fairway or striking a golf ball.
We train them how to develop the right movement patterns and when they play golf this naturally happens. Once your body learns 6-m-1 this becomes automatic this is natural way the body wants to move and create speed.

On the back swing separation or x factor is a myth and not important, all that matter is separation between the hips and upperbody is created on the downswing.

The biggest mistake the X- factor boys made is they don't understand how the body functions.

What they don't understand is why you create separation between the hips and upper body on the downswing. And how you achieve this either.

It's not important to how much your turn your hips in relation to your upper body.The reason you create separation is to elongate the muscles group from the hips to upperbody. The elongation stretches the muscle groups. This also releases a chemical energy which makes the muscles fire. To activate this you only initially need to turn the hips 5 to 10 degrees. Important, once you created separation the lower body must stabilize, so you can you fire the upper body straight away.
If you maintain separation for two long the chemical energy turns into heat. It must be loaded and fired straight away or you lose loading and firing of the muscles.

Th Mistake the x-factors boys made is they don't understand this. They tell you you turn your hips as far left as possible lagging the upper body as long as possible.Ok you have the stretch effect. But the chemical energy has turned to heat, cause you held the stretch to long and haven't loaded and fired your muscles straight away, Now you have lost the chemical energy from holding the stretch to long, the muscles can't load and fire. You have lost the loading and firing of the muscles ,the engines which drive conservation of momentum.

Other two holes with their theory is that they don't understand the lower body must stabilize at impact,this allow you to load and fire your muscles in the upper body. also the lower body stabilizing transfer speed the hips have created to the upper body.(conservation of momentum).
So with their theory you have already lost conservation of momentum and you lost your engine which creates speed loading and firing of the muscles.

The last one is they don't realize they are injuring people. when the upper body is lagged behind and the hips are turned left to much this puts huge rotation torque on the spine. This puts huge forces on the spine and cause lower back injuries.
They don't understand the limitations spine.

It's like Rosey at TPI he's a chiro that's it, he has no biomechanics background, He creates his theories off his chiro background.
Kinematic sequence. Mean to ignore the laws of motion.
So he doesn't understand the laws of human motion and how the body functions or moves and the physics behind it all.

x-factor boys are coming from a mechanics background(golf coaches) they don't understand either the laws of human motion and how the body functions or moves and the physics behind it.

When ever reading up on biomechanics look at their background first.

Okie,
One thing video can't measure is body segments speeds.
Ok there are three thing you need is 6-m-1, conservation of momentum and muscular loading for good physics.
People lose P3 due to arm deceleration as soon as the hands begin to slow down to early in the downswing and the club then is moving faster than the hands and you lose pressure against the shaft. So this is a physics problem not geometry problem.
You have a power leakage somewhere. The arms slow down when you lose conservation of momentum and muscular loading. This could even occurred as early as the from starting from the ground.

Most people pull on the handle and this creates a feeling of P3,
in reality they have poor ball compression and they are adding an external force to the system which is also creating arm deceleration and steering. They pull on the handle to stop an early release cause their arms are decelerating. So it boils down to again poor physics and a power leakage somewhere.

Ok if you have a good grip ,flat left wrist will happen naturally is you have good physics.When you arm sits natural down by your side your hand naturally is flat.

You can believe what you like that's fine, although when you understand how the body moves naturally you will soon understand you can achieve flat left wrist with good physics. If your setup is right and grip is right, good physics you will achieve flat left wrist.

Every athlete I have worked with say to me and they achieve good physics they can feel P1,P2,P3 and P4. Pressure aren't applied they are created and felt from good physics.

Your entitled to your beliefs thats fine, there your beliefs.
Although I have no beliefs or opinions this is what 20 years of measuring 10's of thousands of golf swing tell us. using laws of physics and newtons law and body physics.

Learning biomechanics
 

I have recently started the exercises that BioMechanic teaches. He has also been good enough to answer my many questions. What has been a real eye opener for me is how I have been able to link what Bio has explained to me back to the many, many, many exercises and drills that I have read and watched and been told about over the years. But what he has explained to me doesn't just say "Do this" it is linked back to the basic physical, chemical and mechanical forces that create the results.

For example, why would he say that physics is 90% and geometry is only 10%? Well lets look at 3 fundamentals - FLW, lag and plane. Well if your physics start from the ground and follow the kinetic link up you will get a FLW - how can you not - all of the force is in front of the clubhead. And it is the lag that is generated that leads to a FLW. Certainly you need to obey some fundamental geometry in your set up. But you can more easily have perfect geometry and throw it all away with poor physics that have perfect physics and mess it up through poor geometry. In fact I am finding that my body is creating good geometry while I do the exercises because it I don't everything goes haywire when I hit the impact bag.

As for plane we are all aware of the many incredible golfers over the years whos only brush with plane is through the impact zone. If you work around a stable spine with shoulders and hips aligned you will maintain a really good plane.

And best of all the training makes this automatic. It trains your body to naturally create the right biomechanics. Then you can fine tune your alignments and set up to work the ball how you want.

Not to say that you can't hit a ball successfully with poor physics but good geometry. You can I'm sure. But better with good physics, surely?

Interested in how the highest possible velocity is to be generated? And how do you ensure that you keep it on the optimal path? That is what biomechanics is about, I believe.

Where or how does one learn the exercises that Bioengine teaches???

Ummmm, not sure about the rules here and what I can say, given commercial situation. Don't want to upset Lynn or the administrators. Maybe send Bioengine a PM.

I'm certainly interested in the excercises you use for sure. But I think one thing that we have to keep in mind in studying the similarities of the motions is the amount of precision required in the sport. I was talking to Eddie Cox a little about this. Sure there are some similarities in baseball with regards to the movement . . . HOWVER . . . in baseball you can hit a ball to left or right field and still hit a "good shot".

It would be nice to have a discussion of the exercises you use if it's appropriate with Lynn and you are willing to discuss. I would be very interested to learn more.

Thanks again for posting.

Please review 13-0 and 14-0.

The Physics vs. Geometry argument has been a little out of Focus from the start.

Further clarification
 

I have enjoyed biomechanics posts but find them difficult to follow as written. I particular was interested in this post
What they don't understand is why you create separation between the hips and upper body on the downswing. And how you achieve this either.

It's not important to how much your turn your hips in relation to your upper body.The reason you create separation is to elongate the muscles group from the hips to upperbody. The elongation stretches the muscle groups. This also releases a chemical energy which makes the muscles fire. To activate this you only initially need to turn the hips 5 to 10 degrees. Important, once you created separation the lower body must stabilize, so you can you fire the upper body straight away.
If you maintain separation for two long the chemical energy turns into heat. It must be loaded and fired straight away or you lose loading and firing of the muscles.

I remember years ago it was suggested that those golfers who used too much right hand immobilize the right hand and arm by contracting and holding the muscles for 10 seconds several times before hitting. This used up the chemical and therefore the right side couldn't fire. a cure for hooking.

It would be nice if someone could summarize this thread succintly for an old guy like me. There have been many comments about biomechanics but not much meat shared. Is it priveleged information or available elsewhere for a fee.

I just read your post and didn't catch that 5 to 10 degree thing . . . . My question is where? On the backstroke? Downstroke? Another thing would be what plane angle are we talking about?

As to that deal about contracting and holding muscles for ten seconds . . . I've heard about doing that for some other stuff . . . and it wasn't for no hooking (well maybe it was???). But if people think that's gonna cure a hook . . . . they need to head up to Maine and meet one Mr. Olberdingleberry . . . There is no address but you'll know your close by the distinct stench in the air. Nothing like the smell of goat turds in the morning . . . .

First let me clarify my definite student status on this. But this is my understanding.

The 5 to 10 degrees refers to the downswing. What is being referred to is that when the forces created against the ground at the beginning of the downswing cause the hips to start turning back they actually only need to turn a few degrees to begin the kinetic link. They will then stop, and even counter torque - ie reverse direction momentarily - which will pass the momentum created up to the torso. This force is transferred through the stretch created along the muscles of the torso from the left hip (rh golfers) to the right shoulder. These muscles stretch and then fire (this is a short stretch cycle) creating rotational speed in the torso and shoulders.

Some things that have helped my to understand this:

• Think of Short Stretch Cycles in regard to jumping as high as you can. First you dip down a few inches and then explode upward. This is a SSC. If you drop and pause you lose that energy. If you drop down as low as your flexibility will allow you wont jump nearly as high. Yet in much golf instruction I see pausing and going close to or even to your max flexibility. Biomechanically these don't create the best conditions to create maximum speed in balance.
• The ground forces can easily be understood if you stand on a chair that turns and try and swing a club. These forces are what actually drives your hips around. They are the equal and opposite reaction. Similarly if you move this principle up the chain the equal and opposite reaction when you slow your hips after they've moved back at the start of the downswing will be for your torso to rotate (because your feet are still gripping the ground so the force cannot go that way. Similarly when you slow your shoulders (as Bio says, as they come back into alignment with your hips) that momentum will be passed through your shoulder joint into your arms. Finally your arms will slow through the impact zone and all that energy will be released into the clubshaft which will accelarate massively.
• None of these things can be controlled consciously. Try and throw a ball consciously, maybe by consciously managing how and when your hips turn back on the downswing. I bet you don't throw it that well. But there are exercises we can do to improve these actions. In my case some of them are very golf like involving a club and impact bag. But they are never an actual golf swing and I have to be told time and again not to try and "do" these exercises at the course! :o)

I am writing as an interested amateur. Bio is the expert. But perhaps coming from an amateur as opposed to a technical background I can make this stuff a little more comprehensible to the other amateurs out there!

Very nice . . . thanks . . . . So question WHEN do you jump from the top? Start down? Impact? And how would you describe the jump? Straight up? To the left? Also . . . . How would you jump AND and keep the proper trajectory of the right shoulder and not get the club moving off plane?

Got any descriptions of the exercises or is that double top secret stuff?

Thanks . . . nice thread going here.

Ummm .... ???
 

Ummm ... not sure if you're being funny or if I'm completely missing the point!?! You don't jump in a golf swing. I was using what your leg muscles do when you do a standing leap as an example of an SSC. It's not an SSC that you would actually involve in your golf swing!

As I understand it the SSCs that you activate in your golf swing are across the front of your torso and in the back of your left shoulder (and maybe in front of your right shoulder). There may be others that I don't know about (there is a lot that I don't know about!) All of the Short Stretch Cycles happen in the downswing only, as best I understand it. They start from when your centre of mass starts to move back to the left, which I suspect is best to happen before your arms complete their backswing.

So the SSCs themselves. The torso is activated when your hips rotate back to the left (right if you're a lefty). The hips move before the torso/shoulders which creates "separation" and stretches the muscles as they run from your right shoulder to your left hip. In a proper movement pattern your hips would only need to move a few degrees (so a 10 degree movement would see your hips turn one thirty-sixth of the total 360 degree circle). They hips should then stop (this is one of those things that you can never do consciously and so needs to be trained). This would create the separation and stretch. The muscles across your torso would then fire (this is the short stretch cycle in action). They would shorten which causes your torso and shoulders to turn rapidly around your fairly stable spine.

As you can imagine the turning of your shoulders creates another strech in the muscles at the back of your left shoulder. This is because the arm and club will not immediately move at the same speed as the shoulders (in the same way the shoulders did not immediately move at the same time at the hips). If you think about it this is a process of creating and releasing lag. Lag between the hips and shoulders. Then lag between the shoulder and arms. Then lag between the arms and clubshaft. This is good TGM!

So now we have a stretch at the back of the left shoulder. Proper biomechanics mean that these muscles quickly fire in another SSC and accelarate the arm, dragging the club along for the ride.

The final piece is when the hands stop around the bottom of their arc. This releases the clubshaft and all that lovely built up lag into the back of the ball, sending it flying long and straight down the fairway. Beautiful!

The reengagement of your hips and momentum will then pull your whole body around to the finish.

Exercises
 

I could describe the exercises I do but Bio has advised me against it. The thing is that there are exercises to help you if your hips turn too far without stopping. And there are exercises to help you if your hips don't turn enough before stopping. I don't know exactly what mine do! And without screening you cannot know what exercises you need. You get a personally developed program - I know because I am referred to in the video I got by name!

If I stop my hands sooner, will the Club have more time to pick up greater speed?

Sooner the better
 

Absolutely. Sooner the better. Somewhere around you right ear would work best for you I suspect.

Trebuchet anyone?

What if I just stop them completely?

Hey there Weetbix, loving this thread. I've been thorough the screening process myself and have started my PST's. For me this is the way to go. I had been reading up on the mechanics and had lessons but still could not get the idea of putting my swing together. I'd have good days but couldn't work out why the bad ones were so bad. With Bioengine I've learned how the whole thing goes together and have a solid set of PST's that are in a specific order to train my body to perform this kinetic link with no thoughts getting in the way. I'm striking the ball more consistently than ever.
It was quite amazing what I learned about my swing from the screening too and just how out of whack it was, I was making all sorts of compensations that were causing dire shots.
I was skeptical at first but keen enough about golf to try, I certainly made the right choice and highly recommend this process to anyone who wants to play better golf.

your arms decelerating isn't something you physically try and do in the golf swing, If you try to achieve arm deceleration physically you will hit the ball fat.

The arms slow down they don't actually come to a complete stop.

Each body segment accelerates and decelerates. This must occur for the law of conservation to work.The reason for deceleration of each segment is so speed can be transferred to the next body segment.

In order for this to work you effectively you need 6-M-1 (kinetic link) conservation of momentum and Muscular loading.
If you have all these combinations each body segment will accelerate and decelerate and pass speed to next segment.
(This happen naturally) This continues up through your kinetic Link (6-M-1). Hips,upper body,arms,until distal end speed is transferred to the club.
This all happens naturally when you have trained your body how to create conservation of momentum and muscular loading.

These events you can apply physically by going to the practice fairway grinding balls.

Regarding the SSC this is complicated topic to speak about and for people to understand SSC and muscular loading I would need to write a 50 page essay.There's mountains of information you need to learn, to develop an understanding how this works in the golf swing.

Weetbix.
What do you mean by this below????
Absolutely. Sooner the better. Somewhere around you right ear would work best for you I suspect

Not sure what you mean here ???

I was just screwing with Weetbix.

I agree with much of this but not that deceleration is needed to transfer momentum to the next acceleration stage.

I feel that my own Pivot supplies all of the Work. I also feel that the work that the Pivot provides is separate but synchronized with the Downstroke Acceleration sequence of my Power Package.

My Pivot components don't slow or stop and are sequenced to provide continuous motion and power to the Swing. My Hips lead and power the Shoulders throughout the Downstroke. My Shoulders trail my hips at least until the Finish Swivel.

Foot, knee and Hip Actions are sequenced. Keep in mind that Foot loading is different for Straight and Circle Delivery Paths. So, the Pivot will look different, sequence differently and provide different work. Foot loading is vastly important. Without sensing and sequencing the Ground pressures through my feet and allowing my feet to increase and decrease these pressures, It's difficult to move the Hips very far and it's not possible for the Hips to drive the shoulders through Impact and beyond. Ground Pressures are very powerful and yet can be very sensitive and delicate around the greens. The Sequence doesn't change but the pressures and spacing and pacing of the components changes to fit the shot at hand. It's almost unconscious.

All of this was taught to me by Yoda, years ago.
