I wanted to take a moment for some shameless self promotion
. For those of you who were unaware, I have recently been posting a series of golf blogs in the site's New! Golf Blog section. I look forward to doing this on a regular basis, and I will be covering a variety of topics, hopefully without too many grammatical errors . I would strongly suggest, especially since I penned them, that you check them out. We have recently received many requests about Steve Stricker's golf swing, and I am happy to announce I will be analyzing his swing from the RST point of view in a five part series. In addition to the blog, there will be an accompanying video for the analysis. Enjoy!

Al,
Cool idea. I kind of miss the days when Chuck would analyze popular golf swings. |

I love the idea Al, especially because it makes me want to ask questions! So here is a question about "Why Can't I Stay Centered?".
Simply, do we really want the spine to not move laterally at all? In the RST seminar, I recall a weight shift was advocated. In particular a 2" shift into the right heel. Doesn't this require the spine and head to shift laterally 2" as well? |

Fluffy,
The head will always remained centered even with the weight shift. |

Fluffy,
My father-in-Law asked me the same question about a stationary head being an imperative. My answer; Vertically, the head can and should drop on the downswing but never raise, ala RST weight shift for the downswing. However, it shouldn't move laterally at all, ideally. If it does, I believe the dynamic low point of the swing arc will move with it as moving the head most likely signifies you have moved the biomechanical Fulcrum with it. I define the Biomechanical Fulcrum roughly as the area of the first Thoracic vertebra, T1. We can feel the 7th cervical vertebra as the most prominent spinal bump at the base of the neck especially if you put your chin to your chest. T1 is directly below it. Instead of moving the Fulcrum, the Fulcrum should remain stationary throughout the swing while our Center of Gravity(part of the spine from the belly button down) should shift left (as the hip girdle effectively goes with it). By performing the weight shift this way, the axis tilt we are looking for suddenly appears. This is what I see Al doing in the downswing weight shift video. That left leg is completely and perfectly stacked right over the left ankle (NJA) after moving from the right ankle while keeping the head (and Fulcrum) centered to where you had it at setup. Or, we can use a bell as a simplified analogy. Picture a clapper inside a traditional bell. The stationary point the the clapper is attached to at the top of the bell would be the Fulcrum and the the ball at the bottom that strikes the sides of the bell is the Center of Gravity (our hips). Now imagine if the Fulcrum was constantly moving around at the top of the bell at random. You would not be able to predict from one moment to the next how far you would have to move the ball at the bottom to ring the side of the bell. Moving the Fulcrum introduces a variable that cannot be accounted for repeatably in the time it takes to swing the club. So, I can picture swinging my hips left into NJA as ringing the bell and I should make good contact as long as my low point hasn't moved very far in the process. Unfortunately, being aware of this and being able to perform it correctly are two completely different things. Maybe Al can correct me if I am off here because this is only my interpretation.

My question about lateral movement is really focused on the backswing. If I keep my head still during the backswing and I shift my hips 2" to the right (to prevent that Bender & Leadbetter-esque hip draw to the left), I must change my spine angle in the opposite direction that we all advocate doing on the forward swing.
I'm big on the "question everything", so what is that advantage of keeping your head still while shifting your weight and consequently changing your spine tilt in the opposite way to that desired in the downswing? Alternatively, what if I allow my spine to laterally move a bit during the backswing? Rather than requiring my spine angle to change from one tilt angle to the next, I simply shift it a small amount. That seems much more athletic too. Further, watch CQ's video [Instruction > Rotary Swing Tour > 2. Use of the hips and core - Driver Swing], CQ's head moves back during the backswing. Check out the video at about 2:24. http://www.oneplanegolfswing.com/oneplanemembers/video/index.php?cat=Full%20Swing&subcat=Rotary%20Swing%20Tour&video=109&id=274 Let's keep in mind though what CQ says during the video, "you can over due a good thing". I'm only advocating that we allow the head to move a wee bit to match the weight shift, not some huge sway. So if someone asked me, "do you let your head move laterally?" I would answer, "Yes, but only a small amount." Again my comments are only in reference to the RST backswing. |

That's why I said 'ideally'. You should strive for no movement at all if we are speaking in model terms. This is true for the backswing or the downswing. It does not mean you can't move at all but the lateral movement theoretically has to be recovered on the way back down. That would introduce a reproducibility issue. Check out the very first video on the weight shift. Chuck says something like 'it's a small movement to set the weight to the right and it's only done with my hips (he demonstrates the move right at that point with his hands on his hips). My head stays centered'. It's the video where he says not transferring your weight right and then left will lose you approx 15% in distance.
Again, if the movement is small enough then you may not have to worry about it. However, if I start having fat shots that would be a place to look. Also, just because chuck does it does not mean he is necessarily happy about it. His intent may be to remain stationary with his head as far as lateral movement is concerned. |

fluffy,
Remember why we stand 2 inches outside of nja, it is the widest that we can stand anatomically that will allow for the head to remain centered. What you are saying is true if you are standing too wide. Remember how small 2 inches really is. |

The question here really becomes where is 2" outside NJA. Jeff Broker (our biomechanist expert) just worked on this last week. Originally, Alison Thietje used the center of the hip for the reference point and I had no reason to argue that since that was not my area of expertise. Well, over the past year of working with Alison I questioned every single thing she ever told me because that's how I come to fully understand things for myself. This is one of those topics.
The center of the hips is not the point of rotation, in fact, it is further in than that. Alison used the hip bone as a point of reference, but everyone's pelvis to where their hip socket is located varies. This is one of the reasons you saw my head move, the other was how she advocated the backswing shift to NJA, which I also don't agree with. You see, using this method of measurement, it was impossible for me to shift my weight and have my head not move. Now, in the long run, it's not a devastating thing to have the head move a small amount, but remember I'm on the path to the ultimate in efficiency and consistency and so these variables, while relatively small, are things that I cannot accept. I must know the undeniable, irrefutable facts and absolutes and that is why Jeff and I started to work together. Jeff has his Ph. D. in biomechanics and worked for 10 years for the US Olympic Committee as a biomechanist. He has worked with countless great athletes like Lance Armstrong. His obsession for answers is like mine and like me, he just wants cold hard answers that are unarguable. That's why I challenged Alison on things like this and that's why things have to be tweaked as new information and research becomes available. It's taken a long time, about a year to go through all of Alison's material, experiment with it and research it and slowly we begin to understand each piece more and more and understand things that need to be changed, if even only slightly such as this.
So, long story short, stance width actually needs to be measured by the hip socket itself since that is the point of rotation, not the center of the hip or the pelvis. Now, of course, without an Xray, it's pretty tough for most to determine the hip socket just by feeling it, but most can determine it simply by standing in NJA, in other words, with your feet directly beneath your hips where you feel complete relaxed. This is relatively narrow for most and you will notice that your femur (thigh bone) is curved inward - this is correct and for women it will curve inward even more. From here, you can two inches outside of true neutral and shift all day without your head moving - and that shift needs to only be 1 inch.
Alison advocates 2" because she wants the right hip in NJA on the backswing. Biomechanically, there is nothing wrong with this. But, the crux of the golf swing is getting back to the left and this extra movement is unnecessary and makes it more difficult to get back to the left when the leg is vertical vs. angled slightly in. Shifting into NJA also causes the spine to tilt almost into a S&T type of position which is undesirable. So, a 1" shift keeps everything the way we need it.
Hopefully this helps. I apologize for changes, I know there have been a lot of them over the past year, but I've resolved to the fact that there will always be new information that comes our way through the progress of science. By nature, I'm obsessive and extremely inquisitive and so just settling in and accepting something someone tells me at face value is impossible, that's why I have to go and figure everything out for myself, even if I come to the same conclusion - in which case, this time, I did not.
