Marc Leishman Golf Swing Analysis: Effective...but Not Efficient
Published: March 2, 2026
You may hate this swing analysis.
If you do, it's because we haven't done a good enough job of explaining a crucial concept to you:
The difference between an effective swing and an efficient (and safe) swing.
All PGA Tour players have effective swings, or they wouldn't be on the Tour. Simply put, their golf swings get the job done. But "effective" and "efficient" are two very different things — and that distinction matters enormously for everyday golfers.
But that doesn't mean you should strive to swing like just anyone on Tour, especially Leishman.
All Tour pros have varying levels of swing inefficiencies in their swings, which means they:
Use more muscular effort than necessary to create Tour-caliber impact position and clubhead speeds, and/or
Have to practice more than necessary to ingrain compensating movements for their unnecessary actions — movements that fall apart under pressure.
Worse yet, many have biomechanically unsafe movements that increase their chances of serious injury over time.
(Leishman has both inefficient and unsafe movements in his swing.)
So, when we point out the flaws in these players' swings, it's not because their swings don't work for them. (Heck, Leishman just won $1 million with his!) Want to know where your own swing stands? Run it through our AI swing analyzer to get an objective score on your swing mechanics and movement efficiency.
It's because YOU will likely struggle — or even hurt yourself — if you try to implement their inefficient or unsafe movements. Amateur golfers don't have the thousands of hours of motor pattern practice that Tour pros use to manage their compensations.
So, at this point, you pretty much have 2 choices:
Strive to swing effectively — like Leishman, functional but flawed.
Strive to swing safely, efficiently, AND effectively — producing consistent ball striking without compensations.
Since you're here, I'm hoping you've chosen #2 because that's exactly what you get with the Rotary Swing Tour (RST) system — golf instruction grounded in biomechanics and movement science rather than imitation of flawed Tour swings.
Check out the video now because you'll likely relate to some of the swing inefficiencies in Marc's highly effective swing...
(Plus, you'll find out an unusual stat where Leishman's among the leaders.)

How You Can Avoid Leishman's Inefficiencies
This site has a TON of resources that show you exactly how to move safely and efficiently based on the latest scientific research. Once you understand the proper swing mechanics from the video above, use the GOAT Drill system to lock in efficient movement patterns with measurable, rep-by-rep feedback.
Here are just a few resources you need to check out to start ingraining lasting improvement:
Cure the "flying trail elbow" with the Trail Elbow Pit — the single key to a connected, on-plane backswing
We're after one thing: Real Results - Real Fast.
And that's exactly what our members achieve.
And that's why they say the AXIOM is:
Mind-blowing. Game changing. Revolutionary.
RotarySwing was founded out of frustration with the current state of golf instruction. Quinton knew a better way had to exist to learn this game we all love.
The GOAT Code is finally ready after 3 decades of exhaustive work -
you can now learn how to play the game like Tiger and have incredible
control over the ball. This NEW program is truly a step-by-step process
that takes you from green to tee and will teach you the secrets of how
to play like the Greatest Of All Time. If you would like to switch over
to the new GOAT Code program, simply click the green button below.
Don't worry, you can easily switch back at any time and will see a new
button at the top of your screen to switch back whenever you like.
What are the main advantages of the new program?
It cuts down on the clutter - the videos you will see are all
you need to play your best golf ever - nothing more, nothing less
It is truly step-by-step - no more wondering what you should be
working on, the program guides you through every step of the way
Faster progress - you will see improvements in your scores incredibly
fast and this will immediately begin to spill over into your full swing,
even while working on just your putting!
There's a reason that Earl Woods taught Tiger how to play the game
from the green back.
I admit, at first, even I didn't think it was necessary. I thought I
could skip ahead and learn the full swing without building a solid
foundation in putting, chipping and pitching.
All this belief did was cost me MORE time than had I started
at the beginning just like The GOAT did. Over the past 20 years of
doing golf clinics, my observations of thousands of students was
always the same - those who started the slowest at the beginning
always got there the fasted in the end.
In other words, the students I observed being diligent with the
small things like grip, setup, posture and the basics of controlling
the clubface on day 1 were always WAY further ahead of those who
didn't on day 1.
In the post above by member Everett, he said it all in a nutshell.
Go through the program exactly the way it is laid out and you
will have extraordinary results. Skip to the end and you'll end up
with the exact same swing you started with.
This is a system, not a grouping of random tips.
There is a method to my madness deeply rooted in learning psychology
and over 30 years of teaching hundreds of thousands of golfers
just like you how to hit a ball with a stick. Slow down and you'll
get there faster...
Be sure to watch the video if you can't spot the inefficiency here.
