Here’s Why MCS Is Optimal – Address vs Impact

If you want a simple pictorial illustration of why MCS is the optimal model for the golf swing, let me show you simply how it harnesses leverage over muscle power, creating the effortless-looking swing that you can create with it.

I’ve talked about the “dropping the hammer” concept and how it helps to set up the impact position at address, but when I took it a step further and worked with it a little to combine it with a previous method of setting up the address, something very cool occurred.

That being, watch how close to my impact position my address position is, and this was an actual 7 iron swing (which you’ll see in the upcoming video):

Watch especially the head position at address vs impact, as well as the spine angle and leading foot – if there is one word that would accurately embody what you’re looking at, it would likely be “stability.”

Aside from the slight change in the leading arm position between address and impact (due to the slight difference in the club position at address and impact), the only difference you’re going to see, really, in the lower body, namely the legs and hips.

And that is expected, but it’s a very “quiet” looking transition from address to impact, wouldn’t you say?

How about the address face-on, vs the impact position?

Contrary to the Modern Golf Swing claim that its mechanics are to promote stability in the swing, the reality is the opposite when you look at modern swingers at impact.

I won’t bother comparing the address vs impact of a bunch of modern players, because they aren’t even close, but here is Justin Thomas’ change in position from address to impact, if we’re going to talk about stability:

Justin Thomas Address vs Impact

So, let’s talk about that “stability” for a moment when it comes to the modern swingers…

Here’s one of the top-ranked players in the world below.

There is a definite lack of stability (just watch the head through impact, and then watch the leading foot through impact) at the most important part of the swing, which is at impact:

Jordan Spieth Through Impact

So, creating “stability” by freezing the hips on the back swing (or restricting the turn) doesn’t mean a more stable swing.

All it means is that, by taking about the natural pivot action of the Classic Golf Swing, you will be robbing that swing of its natural leverage, which means you will have to manufacture that power and speed by other means, which usually involves a lot of motion through impact.

If the leading foot and head are moving around through impact, you will be relying on your hand-eye coordination and fine motor skills to create quality shots, and that gets increasingly difficult on days you aren’t “on,” and even days when you are but pressure arises.

Under the gun, you’re more likely to break down when using fine motor skills over gross motor movement (legs & hips).

So, you aren’t guaranteed to have a great swing just because you’re swinging the classic golf swing style, although you’re almost assuredly going to lower your risk of injury swinging.

But if you can build your optimal golf swing, which would have as little “movement” of the critical areas of the body during the swing, you’ll probably be swinging with a classic golf swing model.

And when you can implement the address setup concept that I’ve developed, you’ll truly be building an optimal model,  and then you’ll be swinging with your optimal MCS action!

    This is very interesting

    Can you do a compare and contrast gif with a modern swinger at address vs impact–and then compare those images with yours?

      Good morning, Welshman!

      I’ve added a gif. of Justin Thomas’ positions from address to impact, for comparison’s sake, as you requested 🙂

          Hi HK!

          I’ll see what I can do, but I’ve been looking through YT for some face-on Nicklaus swings with no success. I guess they placed the camera differently back then, because most of the swings are on angled views.

          There has to be a good one out there I can find that isn’t of a 40 or 50 year old Nicklaus rather the vigorous young one, with address and impact captured clearly.

    Hey DJ any thoughts on something that becomes problematic for me. Even with an effortless motion you still need to be, I’m going to use the word aggressive when going after the ball, not getting to lazy, and decelerating on the down swing, this with the longer clubs in particular is where I can get in trouble where trying to be “aggressive” can become over exaggerated which then turns into over swinging IE no bueno, or not aggressive enough which causes deceleration on down swing, again we all know that’s no bueno.

    Also wondering if you, or anyone else you have spoken with about the MCS swing has experienced lower back pain, and tightness in the right buttocks muscle from the spine tilt at address (before even swinging when I get into the tilted spine set up I get discomfort, but I do have back issues so this could be related to that, and that position isn’t ideal for me personally, or I could just be swinging too much, and my body needs a rest).

      Hi Lupz!

      Well, this is the whole point of the proper set and mechanical action – I’m going after the driver in that above clip pretty much as hard as I’d go after a drive, and you can see that I don’t get out of position because I’m in the optimal position from address.

      So, that is the obvious and added benefit to having a proper setup, in that you can swing as hard as you please and not “over-swing.”

      As to your second paragraph – you likely answered your own question in the bracketed part:

      I do have back issues so this could be related to that, and that position isn’t ideal for me personally, or I could just be swinging too much, and my body needs a rest…

      There is nothing in the right-biased setup that should cause discomfort, other than perhaps some muscle soreness and stiffness at the beginning of the change, due to the muscles simply not being used to that position and/or motion.

      But it’s the mechanically-correct way to stand if comparing it to the optimal impact position, and Nicklaus himself was set up pretty much that way at his best (and recommended that in his setup philosophy), which you can compare to my setup in the clip:

      So, it’s either your back being the issue to begin with, or just muscle fatigue due to changing the position and/or having swung enough to need some rest.

    I can comment as this was the reason I came to this website in the first place.

    The headline: Adopting this swing (or my embryonic version of it) has eliminated the lower back pain I got from golf.

    I started playing in the my late 40’s and stopped after 5 years. I took it up again last year (now I’m nearly 60).

    I played about 4 rounds, and after each I couldn’t walk the next day. I had a lousy, inefficient modern swing. I had little distance and would compensate by trying to swinger harder and faster. Throw in poor back mobility because of age, sitting and rugby injuries, and my SI joints were screaming at the prospective of hitting a golf. I could never hit a full jumbo bucket.

    A friend of mine in the UK was in exactly the same position and he found full relief and a return to golf enjoyment after taking some lessons from a guy called Brian Sparks—the Danse du Golf

    I liked Sparks’ stuff and it was through researching his approach that I came across Wax Golf.

    I have adopted DJ’s method, and though I’m still trying to make it my own, I can say one thing—I am now playing pain free golf.

    I can now

    – hit a jumbo bucket
    – then play a round of golf
    – then hit another jumbo bucket.

    I am in the middle of the pack of my golfing buddies in terms of driving distance of the tee, but in the top quartile of fairways hit.

    They use 460 cc $300-$500 drivers. I am hitting a $2 persimmon 3 wood bought in a garage sale.

    Last week I hit a ($2) persimmon 3 wood and then a ($1) persimmon 4 wood and got on the green of a 480 yard hole—-PAIN FREE!

    I have spent the money and bought a SwingRite and find that it is great to help burn in MCS.

    It’s now my short game which is coming into focus.

    But even if I’d made no progress in scores, I am PAIN FREE and that’s a big thing to me.

    Hope this helps

      Welshman does not exaggerate – when we first met, he was struggling to get a 3 iron out to where he’s now hitting 8 and 7 irons.

      Most impressive? His learning curve and (witnessed by David D.) on Monday when we were shooting my swings for the upcoming video, I gave him my 7.5 degree KZG PFT300 driver (hey Jim! 😉 ), without telling him the loft.

      He proceeded to slam out some nice, arcing drives about 245-250 carry, and this is a very heavy driver with a small head size.

      And, as he testifies above, it’s all in the setup and pivot action!
