You need to understand your golf swing “signature”

Published

on

The golf swing is one of the most complex movements in all of sports. The search for the perfect swing started hundreds of years ago, and we have seen it develop at a rapid pace in the past 20 years. Equipment companies, universities, the USGA, and NGF are just some of the agencies that have attempted to solve the riddle of golfer performance.

So what have we learned to date?

That was one of my biggest questions when I set out on a voyage to sort through all that was available in the world of published golf research, and it led me to where I am today. I decided that I would need to own and develop my own golf swing analysis software, a project that became a fusion of my years of teaching experience with a man I think is the most influential researcher in the history of the game, Dr. Steven Nesbit.

People often ask me what we’ve learned so far, and I tell them that we have uncovered a lot about how the golfer influences and puts their load on a golf club. Through the use of optical 3D-motion capture (I use a system called GEARS), we collect a swing’s data points and then process that data in a mathematical logarithm that we have designed to report on how the golfer pulled, pushed, and twisted on the grip to create the movement that you see.

The way in which the golfer influences the club is extremely complex, and the explanation of exactly what is happening in a golf swing explains why the game is so difficult. There are so many variations in style with so many factors intertwined that it makes the explanation fascinating, but often not all that satisfying. Many golfers are looking for that one idea that will transform their swing and game. What we have found is that it’s never just one thing; it’s many things wrapped together, and sometimes the solution can turn up to be something completely unexpected.

My Jacobs 3D’s proprietary golf research software takes the recorded data and processes the actions of the golfer to show how the golfer created their movements. It runs as deep as analyzing the movement of each major joint in the body and how every separate joint can affect the whole. Using it, we have begun to isolate the traits of superior golfers. There are a set of parameters that we can say are characteristics of a high-performing swing, and as time goes on we will share all of these with the GolfWRX Community.

There is, however, one thing that is unique to every single golfer: a swing “signature,” so to speak. A swing signature is the path that the movement of the center of the golfer’s hands take during the swing, which we call the “hub path.” The images below are from my book Elements of the Swing, which explain the hub in detail.

The-Hub

What does a golfer’s hub path tell us? We have found that the unique movement of this Hub Path can give an overall picture of the internal and external movements of the golfer. It can describe how a golfer is taking advantage of motion of the body, but it can also show how a golfer is compensating for their weaknesses in body movement.

In the video at the top of the story, I explain how you can figure out your own Hub Path and how you can use it to analyze your swing. I hope you enjoy it!

    One can only wonder how Jones, Nelson, Snead, Hogan, Nicklaus, Palmer and Player coped with the golf swing.

    The golf swing is not a complex movement at all……..you can sure make it that way if you want!!!

    Pretty interesting. However I think shaft deflection is sorely lacking in the models. Without knowledge of exactly where the shaft is bending and in what orientations knowing where the hands (hub in your lexicon) and clubhead are are somewhat meaningless. In other words. In large part the way a tour player releases the hands thru impact is a direct result of how they use forces to load the shaft. Club face angle is really key as well in determining what signature a golfer employs.

      I am familiar with shaflab. I don’t think they reached the conclusions you describe. Even if they did, its ancient technology – Fujikura’s Enso lab is a much better tool and they certainly don’t reach those conclusions. The Laws of the Golf Swing sounds more like the maybe there’s a propensity for this thing that we are going to claim is a law regarding the golf swing. I’m not buying loading patters and body type are any more than ever so slightly positively correlated. Why? Because I see so much evidence against it.

    I have Zepp. Not really of any help to me. I think things like it are only band aids that cause you to manipulate the club to obtain a picture perfect result. It’s just to support the concept of a positional golf swing as opposed to a directed energy (my term)) swing such as taught by Shawn Clement.
    Of course, golf being what it is, use whatever works for you.

    Hi Michael!
    What methods do you use to get the higher handicap player to close in on the tour player characteristics? What was the focus at the time of the swing in each of the players graphs that you displayed here?
    Thank you! Shawn

      Must be something like apply force along the shaft, away from the target initially, tuck that right elbow and start extending the arm, twist around the shaft to close the face, get your hands wide and low, then yank it up through impact. I would say the hub path describes an athletic motion like throwing a ball far; you load the right arm, flex the elbow, then the elbow leads as you extend the arm. The intent – I don’t think there is an intent. I think top players watched others when they were young and allowed a human being’s own innate ability to throw (or do anything athletic) develop without conscious thought. When I’m throwing at a target I’m thinking of nothing, all someone once told me was ‘if your ball hits the target before the runner they are out’.

      In this instance, I would say to a high handicapper with a poor ‘hub path’ either intend to throw later, or at a different target. I might pose them an impact with body open and shaft leaning, get them to release the club forward five times and then let them ‘just swing’. All are generally surprised at the amount of lag they have without thinking about how they got to and through such a ‘position’. Or with a really top player I might work on them getting tier hands wider initially in transition whilst holding on the right leg.

    Zepp shows your hand path. SkyPro will show you more data e.g. face angle at p6. But is on the shaft. SkyPro is also good for putting e.g. face angle at impact. Both $150. I recommend them both.

The Wedge Guy: The easiest-to-learn golf basic

Published

on

My golf learning began with this simple fact – if you don’t have a fundamentally sound hold on the golf club, it is practically impossible for your body to execute a fundamentally sound golf swing. I’m still a big believer that the golf swing is much easier to execute if you begin with the proper hold on the club.

As you might imagine, I come into contact with hundreds of golfers of all skill levels. And it is very rare to see a good player with a bad hold on the golf club. There are some exceptions, for sure, but they are very few and very far between, and they typically have beat so many balls with their poor grip that they’ve found a way to work around it.

The reality of biophysics is that the body moves only in certain ways – and the particulars of the way you hold the golf club can totally prevent a sound swing motion that allows the club to release properly through the impact zone. The wonderful thing is that anyone can learn how to put a fundamentally sound hold on the golf club, and you can practice it anywhere your hands are not otherwise engaged, like watching TV or just sitting and relaxing.

Whether you prefer an overlap, interlock or full-finger (not baseball!) grip on the club, the same fundamentals apply.  Here are the major grip faults I see most often, in the order of the frequency:

Mis-aligned hands

By this I mean that the palms of the two hands are not parallel to each other. Too many golfers have a weak left hand and strong right, or vice versa. The easiest way to learn how to hold the club with your palms aligned properly is to grip a plain wooden ruler or yardstick. It forces the hands to align properly and shows you how that feels. If you grip and re-grip a yardstick several times, then grip a club, you’ll see that the learning curve is almost immediate.

The position of the grip in the upper/left hand

I also observe many golfers who have the butt of the grip too far into the heel pad of the upper hand (the left hand for right-handed players). It’s amazing how much easier it is to release the club through the ball if even 1/4-1/2″ of the butt is beyond the left heel pad. Try this yourself to see what I mean.  Swing the club freely with just your left hand and notice the difference in its release from when you hold it at the end of the grip, versus gripping down even a half inch.

To help you really understand how this works, go to the range and hit shots with your five-iron gripped down a full inch to make the club the same length as your seven-iron. You will probably see an amazing shot shape difference, and likely not see as much distance loss as you would expect.

Too much lower (right) hand on the club

It seems like almost all golfers of 8-10 handicap or higher have the club too far into the palm of the lower hand, because that feels “good” if you are trying to control the path of the clubhead to the ball. But the golf swing is not an effort to hit at the ball – it is a swing of the club. The proper hold on the club has the grip underneath the pad at the base of the fingers. This will likely feel “weak” to you — like you cannot control the club like that. EXACTLY. You should not be trying to control the club with your lower/master hand.

Gripping too tightly

Nearly all golfers hold the club too tightly, which tenses up the forearms and prevents a proper release of the club through impact. In order for the club to move back and through properly, you must feel that the club is controlled by the last three fingers of the upper hand, and the middle two fingers of the lower hand. If you engage your thumbs and forefingers in “holding” the club, the result will almost always be a grip that is too tight. Try this for yourself. Hold the club in your upper hand only, and squeeze firmly with just the last three fingers, with the forefinger and thumb off the club entirely. You have good control, but your forearms are not tense. Then begin to squeeze down with your thumb and forefinger and observe the tensing of the entire forearm. This is the way we are made, so the key to preventing tenseness in the arms is to hold the club very lightly with the “pinchers” — the thumbs and forefingers.

So, those are what I believe are the four fundamentals of a good grip. Anyone can learn them in their home or office very quickly. There is no easier way to improve your ball striking consistency and add distance than giving more attention to the way you hold the golf club.

Clement: Stop ripping off your swing with this drill!

Published

Not the dreaded headcover under the armpit drill! As if your body is defective and can’t function by itself! Have you seen how incredible the human machine is with all the incredible feats of agility all kinds of athletes are accomplishing? You think your body is so defective (the good Lord is laughing his head off at you) that it needs a headcover tucked under the armpit so you can swing like T-Rex?

How a towel can fix your golf swing

Published

on

This is a classic drill that has been used for decades. However, the world of marketed training aids has grown so much during that time that this simple practice has been virtually forgotten. Because why teach people how to play golf using everyday items when you can create and sell a product that reinforces the same thing? Nevertheless, I am here to give you helpful advice without running to the nearest Edwin Watts or adding something to your Amazon cart.

For the “scoring clubs,” having a solid connection between the arms and body during the swing, especially through impact, is paramount to creating long-lasting consistency. And keeping that connection throughout the swing helps rotate the shoulders more to generate more power to help you hit it farther. So, how does this drill work, and what will your game benefit from it? Well, let’s get into it.

Setup

You can use this for basic chip shots up to complete swings. I use this with every club in my bag, up to a 9 or 8-iron. It’s natural to create incrementally more separation between the arms and body as you progress up the set. So doing this with a high iron or a wood is not recommended.

While you set up to hit a ball, simply tuck the towel underneath both armpits. The length of the towel will determine how tight it will be across your chest but don’t make it so loose that it gets in the way of your vision. After both sides are tucked, make some focused swings, keeping both arms firmly connected to the body during the backswing and follow through. (Note: It’s normal to lose connection on your lead arm during your finishing pose.) When you’re ready, put a ball in the way of those swings and get to work.

Get a Better Shoulder Turn

Many of us struggle to have proper shoulder rotation in our golf swing, especially during long layoffs. Making a swing that is all arms and no shoulders is a surefire way to have less control with wedges and less distance with full swings. Notice how I can get in a similar-looking position in both 60° wedge photos. However, one is weak and uncontrollable, while the other is strong and connected. One allows me to use my larger muscles to create my swing, and one doesn’t. The follow-through is another critical point where having a good connection, as well as solid shoulder rotation, is a must. This drill is great for those who tend to have a “chicken wing” form in their lead arm, which happens when it becomes separated from the body through impact.

In full swings, getting your shoulders to rotate in your golf swing is a great way to reinforce proper weight distribution. If your swing is all arms, it’s much harder to get your weight to naturally shift to the inside part of your trail foot in the backswing. Sure, you could make the mistake of “sliding” to get weight on your back foot, but that doesn’t fix the issue. You must turn into your trial leg to generate power. Additionally, look at the difference in separation between my hands and my head in the 8-iron examples. The green picture has more separation and has my hands lower. This will help me lessen my angle of attack and make it easier to hit the inside part of the golf ball, rather than the over-the-top move that the other picture produces.

Stay Better Connected in the Backswing

When you don’t keep everything in your upper body working as one, getting to a good spot at the top of your swing is very hard to do. It would take impeccable timing along with great hand-eye coordination to hit quality shots with any sort of regularity if the arms are working separately from the body.

Notice in the red pictures of both my 60-degree wedge and 8-iron how high my hands are and the fact you can clearly see my shoulder through the gap in my arms. That has happened because the right arm, just above my elbow, has become totally disconnected from my body. That separation causes me to lift my hands as well as lose some of the extension in my left arm. This has been corrected in the green pictures by using this drill to reinforce that connection. It will also make you focus on keeping the lead arm close to your body as well. Because the moment either one loses that relationship, the towel falls.

Conclusion

I have been diligent this year in finding a few drills that target some of the issues that plague my golf game; either by simply forgetting fundamental things or by coming to terms with the faults that have bitten me my whole career. I have found that having a few drills to fall back on to reinforce certain feelings helps me find my game a little easier, and the “towel drill” is most definitely one of them.
