This was fun to kick start my YouTube channel off again after a couple of years break, I’m super proud it is a world first drill too!!

“The Intensity Drill”

See it first here -
https://youtu.be/OSkNWw1EVPg

Using the Downshift board I trained my vertical force, increasing the combined force value by 70%! Timings improved also, my peak value was earlier and my club head speed increased by 11 MPH. Incredible!!

Using the board for immediate feedback and purposely rating each effort on a scale of 1-10, I was able self-quantify my “feel” for the amount of press down (pressure) under my lead foot.

With the full drill I was able to increase force and speeds in just 3 swings and less than 5 minutes, using dual 3d force plates and @trackmangolf to measure the actual gains. No BS.

@downshiftgolf board is an excellent training aid, if you haven’t got one you need one.

Your welcome 🙌🏼

Joh and Dodo’s speed session. Its was great to have these two in for a push! Did they go faster? We discussed our work to date and some future changes. taken in The American School of Bangkok Green Valley by @sfgolfperform

🇹🇭 8 MONTHS. 1 GOAL. #1 IN THAILAND.

Eight months ago, our journey started.

Joh reached out to me frustrated that his speed had plateaued. He simply couldn’t get beyond 140 mph clubhead speed with his previous tutor.

From day one, my advice was explicit:

No shortcuts. No corner cutting. Change the lifestyle. Make the mechanical changes. Go ALL IN.

Over the following seven months, Joh has shown incredible consistency and discipline 🙌🏼💪🏼.

The work hasn’t been just technical. We’ve worked meticulously on specific swing mechanics, ground reaction forces (GRFs), sequencing and speed development, while also transforming the physical side of his game.

Under the watchful eye of his personal trainer Dodo, Joh has put the work into his body to support what we are asking him to do with the golf swing.

What makes me most proud isn’t simply seeing him become Thailand’s fastest golfer.

It’s watching him learn through both the failures and the successes — and then seeing that work translate into becoming a winner.

220.7 mph ball speed. 151.9 mph clubhead speed.

And we’re not finished yet. 🔥

This Friday, 18th September at 1:30 PM, Joh and I are going LIVE on Instagram.

Joh will be taking on one of his Speed Push sessions, so who knows… we might see another PB. 👀💨

I’ll be chatting with Joh about the journey, the work we’ve done together, the failures, the breakthroughs, and what it has taken to make him #1 in Thailand.

JOIN US LIVE.

🇹🇭 Joh — Thailand’s fastest golfer
🔥 Speed. Power. Passion.
📅 Friday 18th September
⏰ 1:30 PM
📱 Instagram LIVE

Let’s see how fast he can go. 💨🏌️‍♂️

Look at Matthew Fitzpatrick. He isn’t just swinging; he’s loading the ground to aid his clearing action. 🚀

Every elite ball striker uses the ground to power their “Invisible Engine.” 🤫

Stick around for some other drills later in this video. 👇

Today, we’re going to compare a winning tour pro’s perfect A/P force data against an amateur golfer who suffers from early extension. 📉

Most amateurs get the GRFs wrong. They let their trail foot dominate by peaking their A/P force first, thrusting their trail hip and pelvis toward the ball. This is the definition of early extension, and it’s the root cause of your inconsistent impact. ❌

To fix this, look at the physics. Newton’s Laws tell us that to move your lead hip backward, we need force—Ground Reaction Force. 🌎

We can see on the new @smart2move companion app , this pro is pushing aggressively into his lead foot, using the ground’s equal and opposite reaction to force his hip backward and clear out of the way. ✅

The “Two-X Rule.” 🔢 Pros don’t have a 1:1 ratio between their feet. They generate 2x or more A/P force on their lead side at the halfway downswing point. ⚡️

Are you an amateur who early extends, or do you apply the 2x rule? It’s time to find out. 🧐

Want to measure your A/P ratio?

Save this post and share with a friend that needs help with their GRFS for a chance to win a 3D Smart2Move lesson with your local coach and unlock your Invisible Engine. 🏆

🚨 CALLING ALL GOLF COACHES! 🚨

I WANT TO PAY YOU FOR A LESSON.

My multi-part video series deep-diving into Ground Reaction Forces (GRFs), the elite kinetic sequence, and maximizing Torque Z is blowing up with data-hungry golfers. 🚀

To bridge the gap between theory and the driving range, I want to give back to the community. I am personally buying a full Smart2Move force plate lesson to give away to one lucky viewer—and I want to purchase that lesson from YOU and send a winner straight to your academy. 🫵

Here is how we win together:

💸 I Pay Your Full Rate: A local golfer gets a world-class session on your Smart2Move plates, fully funded by me.

📈 Massive Exposure: I’ll be actively promoting your academy to my audience as the go-to GRF expert in your area.

📱 Follow-Up Content: After the lesson, we’ll use the Smart2Move iPad Companion App to share the student’s before-and-after data in a collab post, showcasing your coaching expertise to thousands of prospective students.

All I ask in return is that you help support the lesson series by sharing the recent and upcoming videos to your feed, stories, or student database so we can get more golfers understanding, measuring, and mastering their ground forces. 🏌️‍♂️💥

Ready to join the GRF revolution? 👇
💬 Comment and DM “COACH” to get started!

The Trigger & Transitioner You Didn’t Know Existed 🤯🏌️‍♂️

Ever wonder how the world’s best ball strikers generate effortless power and flawless timing? It partly comes down to the Fy-Axis (Lateral Force).

In the golf swing, this side-to-side force handles two massive jobs: it acts as your Trigger and your Transitioner. If you want a repeatable, powerful delivery, you need to master how your feet interact with the ground.

Stick around until the end of the video to see my favorite lateral force drills! 🧠🔥

Here is the exact elite sequence from P1 to P7:

🎯 1. THE TRIGGER PHASE (Initiation)
P1 (Address): Before the club even moves, top players use a micro-shift. Force precedes motion—the lead foot applies force, creating a negative (away) Fy ground reaction.
P2 (Takeaway): The trail foot quickly takes over with a push away, creating a positive (towards) Fy ground reaction. This is where your sway brake activates!

🚀 2. THE TRANSITIONER PHASE (Shift to Lead)
P2 to P3.75 (The Secret Move): This separates elite ball strikers from recreational players. Elites start their lateral Fy early, maxing it out under the trail foot just before the top of the backswing. They are actively pushing laterally to sway the pelvis toward the target early.
P4 (Top of Swing): By the time the club reaches the top, that trail foot Fy is already in decay. The pelvis is already shifting while the club is still traveling backward. If you wait until the club stops to shift, you’re too late!

P6 to P7 (Pre-Delivery): Most of the target-side sway is done. Lateral brakes slam onto the lead foot, maxing out around P6. The weight transfer is complete, clearing space for a powerful impact. 💥

🎁 GIVEAWAY ALERT! 🎁
Want to master this transition and measure your own ground forces? I am giving away a FREE force plate lesson with your local Smart2Move coach!

The Invisible Engine: Force Precedes Motion 🌪️
Before your club even moves, your body—via your feet—is having an invisible conversation with the ground. 👣⛳️

If you want to build a swing like an elite player, you have to master the 3 dimensions of Ground Reaction Forces (GRF). Here is what they actually control:

🔴 Fy (Lateral Force): The side-to-side force aiding sway and side bend.
🟡 Fx (Anterior/Posterior Force): The front-to-back force driving thrust, front and back bend, and rotation.
🔵 Fz (Vertical Force): The vertical force that creates explosive speed, aiding rise and side bend.

Over the next month, I will be breaking down exactly when these forces and torques need to peak to optimize how you move and swing the club. 📈

👇 Hit follow, save this post, and share it with your friends who want to take their swing to the next level! There will also be a force plate lesson giveaway during the series so stay tuned 🙏🏼.

@smart2move

Thank you and credit to @padraigharrington , @golfzillazuback for letting me use your GRF data from your 3D force plates
