There are two “arcs” in the swing which must be understood if one is going to swing optimally, as they are not as you see in video or pictures – they are an optical illusion, actually.
The first arc is the vertical arc which, as I have combined two pictures that show the blurred arc of the club head before and post-impact, to show you what is meant by “descending,” “level” and “ascending” impacts.
As you can see, there is an arc here, and you cannot create a longer “flat spot” at the bottom of this arc – is impossible.
This also illustrates why a stable head is necessary to swing optimally – if the head moves left or right, that arc will shift, and then you won’t be where you wanted to be, if you were set up in the proper place to begin with.
The second arc is viewed from above, and shows another theoretical arc horizontally to the ground and again will illustrate why you can’t create a “flat spot” in your swing, and why, if you shift left or right during the swing, you will also shift the arc, and lose consistency.
And now we get to the reason these are “theoretical” arcs – you will never swing a golf club to create either arc in a regular swing – the vertical arc is that of a Ferris Wheel, and we don’t swing that way.
The horizontal arc is that of a Merry-Go-Round, and more of a baseball swing type action, and we don’t swing that way either (unless we are Ernie Els hitting out of the gorse at the British Open).
So, the two arcs combined – that is the true swing arc, and it looks like this:
The true swing arc is neither vertical nor horizontal, but rather inclined as you can see, following the club head in the swing gif. above.
I call the swing arc an “Inclined Ferris Wheel.”
And this is why, if you are going to swing a golf club with optimal athleticism and mechanical-correctness, you have to build a stance and have the mechanical action necessary to make your swing arc consistent and stable – meaning it’s the same arc every time you make a standard swing, and it doesn’t move from address to impact.
My particular issue with the golf swing, over the years, has been that my scoliosis (curvature of the spine) made it impossible to create a proper swing arc with a standard stance.
Jerry “BT Crowell, PGA
I cannot stand over the ball the way a standard-built person like Jerry “BT” Crowell, which is why he is my “standard swing” model – if you don’t have any past injuries or congenital conditions that alter your motion or arc, then you have a relatively easy time establishing and maintaining your arc – or at least you shouldn’t!
And in the upcoming “MCS – Perfect Pivot“ video, I will explain how I found my own adjustments to the standard MCS address position so that I could create my own optimal swing arc.
DJ’s MCS Swing DTL – Adjusted For Scoliosis
Viewed face-on, you don’t see the adjustment, but down the line, you see how I have to stand in order to swing through the ball with the proper arc and plane, in order to perform my own Ben Hogan-style “perfect pivot” leg and hip action:
Hey – I’m just a swing researcher and analyst and if I can be a 46 year old man (as of this week), overweight and out of shape by a mile compared to my athletic peak and, with a twisted spine, can still generate 130 mph club impact speed and 195 mph ball speed without training or hurting myself – I can only imagine what someone else could do with their MCS model.
Wait, we already know what one can do – you can be 50 years old and have had a back injury from swinging in the modern swing style a few years earlier – and be driving the ball straighter and longer, and swinging faster, than you ever have, even in your so-called “prime” years.
Like Jerry – who will be 51 this year and who last month set a new club impact speed high of 124.2 mph and who is driving the ball well over 300 yards – in fact, he’s carrying it 300 on good pops.
“Very nice…Now Hit A Fade…”
So, he’s got that going for him!
