I like discussing the golf swing. Whether you call it "swing theory" or what, I like to talk about things that can expand the potential for what I know and understand. As a scientist, I like being shown that I'm wrong, too, because as I've said a bunch of times… "you're wrong and here's why" is an instant opportunity to upgrade my knowledge. I also like to help golfers, and one of the things I'm most glad to have moved away from from 15 years ago was the "Hands In" idea from S&T. Jim Waldron is often credited (probably rightly so) with explaining why so many Tour players and good players talk about "keeping their hands in front of themselves" while it appears that they're moving their arms around their bodies. From over 30 years ago: I've also got videos like… this (Instagram link here😞 I'm happy to say that I've become friends with Shaun and Mike at Athletic Motion Golf (AMG), too. I tend to get along with other smart folks who measure things, who look critically at information, who don't assume that what they thought 20 years ago holds true today. I get along with folks who look for chances to instantly upgrade their knowledge. Andy Plummer remains one of the people who does not look for these opportunities. He didn't care in early 2013 when we had evidence that the information in their S&T 2.0 DVDs was bogus, and they seemingly don't care now. They've been attacking (it's their favorite pastime) AMG in particular for the better part of a year now. There have been a few shots back at them from AMG (like… this), no doubt. But as is typical of the AMG fellas, it's with measured data. Well, recently, Andy took yet another shot at AMG: https://www.instagram.com/p/DZfHe0DuPXC/. Andy demonstrates that true power in the golf swing comes from doing stuff like this: Andy claims that the idea that the arms mostly lift and lower, while the body turns, is bogus. What golfers should be doing is using "angular velocity" to abduct and adduct their shoulders to move the club fast like this (above). Then he makes a ridiculous example of what AMG supposedly teaches, but misses by a mile. Now, it doesn't take a biomechanist to know that you can't possibly swing as Andy demonstrates. His right arm is so far around and behind him that his left arm would have to grow several feet to reach the grip of the club (or alignment stick), and a follow-through with the right arm position like that would be absolutely silly. But, it's a demonstration, so let's not read too much into it. However, I find ideas like this dangerous. Again, I like to help golfers, and in my opinion, the idea that you should abduct and adduct your arms a lot is a dangerous one. There's some adduction and abduction going on, but… it's not much. Anyway, this statement was posted: 130 degrees of dynamic range of horizontal abduction and adduction is quite the claim! I posted some comments to Andy and others, and was issued a challenge: Well, okay then. Here's Bryson's lead shoulder adduction: This measures the angle between the "virtual spine," the left shoulder, and the elbow. Bryson has a 97.34° "adduction angle" at P1, a 62.53° angle at P4, and returns to an 89.21° angle at impact. Rounding, that's a change of 34° from address to the top, and then a change (back toward the angle at address) of about 26° from the top to impact. If we want to worry about only horizontal abduction and adduction (where D = adduction and B = abduction): Left shoulder: 8.33° D, 38.74° D, 14.67° D Right shoulder: 1.03° D, 55.75° B, 14.04° B If we call moving the arms farther around you as negative, those are changes of -30.41° from P1 to P4 for the left shoulder and +24.07° from P4 to P7 for the left shoulder and -56.78° and +41.71° for the right shoulder. I have no idea on earth where he gets 130°. From the last frame of Bryson's swing where he's at 126.98°? But the lowest that number gets is 62.53°, for a range of 64.45, or less than half of the 130° claimed (plus it includes part of the swing, post-impact, that has no bearing on what the ball does). For good measure, another pretty good player: Left: 22.55° D ➡️ 33.35° D (∆ 10.8°) ➡️ 17.36° D (∆ 15.99° from P4, 5.19° from P1) Right: 15.03° D ➡️ 24.29° B (∆ 39.32°) ➡️ 1.93° D (∆ 26.22° from P4, 13.1° from P1) Of the biomechanists and experienced 3D users (on any platform), none of them have seen anything like 130° of dynamic adduction/abduction from a good player P1 to P7. And, like my little joke above, even if you go to the end of the swing, you rarely get much more than a little over halfway there. Maybe Andy is adding them? He does say in the video "and then add it to that with the lead arm." (I think that's what he says, but this isn't an additive type system.) I regularly coach golfers out of positions with a lot of adduction and abduction. I regularly work golfers away from moving their arms around their bodies. Even my juniors (the ones who have paid attention anyway! 🤣) can recite "arms = up/down, body = around." Like this: So, I don't know where this leaves us. Andy claims to have seen something on GEARS that shows 130° of dynamic adduction/abduction. I'm open to being wrong, but… I don't think I am here on this one. And, until that comes to be, I will continue to stand up for what I think is the best information, and do my best to work with golfers toward simpler, easier moves that don't get them stuck. Simpler, easier moves like the moves Tour players and great players tend to make, not complicated, difficult moves. Shaun and Mike said it in a video once where they demonstrated that the average Tour player adducts their lead arm 20° across their chest from the top to impact (P4 to P7), while the amateur often tries to go 40°. They said something like "the amateur is trying to move their arm TWICE the distance in the same amount of time as the professional athlete." Yep. The swings of great players are often easier and simpler. They are not abducting and adducting their arms much in comparison to average golfers. As a smart man once said: "Why would you teach something (abduction in this case) that bad golfers already do?" On a related note… the S&T crowd continues to be… well, who they've been as long as I've known them. Take this comment for example: I mean… I would think that this is pretty self-explanatory, but then again… I didn't think it needed explaining to begin with. P.S. As I was finishing up this article, another biomechanist replied with something so simple I hadn't even thought of it as I had immediately jumped into looking at the actual measurements: "90 doesn’t even seem physically possible.“ No, sir. It doesn't. -
Day 285 6-14 practiced low point control in some dirt by our garden. Objective was to see how far infront of a set point I could get the divot. No ball. -

Interested to hear from those who have gone through something similar. I'm currently around a 9 handicap and have logged 50 rounds so far this year. My issue isn't really my handicap itself, it's the amount of score variation. Looking back through the year, I've had scores ranging from 73 to 95, with everything in between. Within the last week alone I went: 92 - 74 - 80 - 89 - 93. I appreciate there is always a variance to scoring and that is fine but I seem to have the issue of being capable of a mid to low 70's round and then the next day adding 20 shots onto that. Others I know around my handicap, they seem to live in the low-mid 80s and occasionally shoot high 70s. In contrast, I seem to have a very high ceiling and a very low floor. My goal is to get to 5 but I feel a million miles away from that at the moment. I have had periods of lessons where I have got better but that baseline level never seems to have improved and the only sort of logical conclusion I can come to is because my fundamental ball striking and clubface control is not good enough. Over the years I've been through the usual cycle of swing thoughts and feels. Something works for a few rounds and then it disappears. This latest episode involved a "looser arms, smoother swing" feel which coincided with some good golf before scores drifted back upwards this week. The more I look at my scoring record, the more I wonder whether the answer is much simpler. Perhaps score volatility is ultimately just a reflection of strike and clubface variability. If strike and face control vary significantly from day to day, then perhaps 74 one week and 93 the next shouldn't be surprising. So my questions are: Has anyone else experienced this sort of variance? Did you eventually become more consistent, and if so, how? Was it primarily technical, mental, course management, practice-related, or something else? Did you manage to raise your floor, or are some golfers simply naturally more volatile than others? Interested to hear from anyone who has gone from being a "74 or 94" golfer to someone who lives in the 70s and low 80s. -
