Most golfers try to control the club.
But the club is just a reaction.

Real power starts from the ground:
	•	Down before you push
	•	Load → Unload → Rotate
	•	Let the club react to what your body is doing

If you’ve been trying to hit positions…
This is why it feels tense.

Golf is a throw.
But without looking.

Learn to feel the ground → the rest follows.

The secret to effortless shallowing.

It’s not about pulling the club down — it’s about throwing it out.
When the arms leave the body, the pivot finally gets to do its job.

More torque. More leverage. More sequence.

“When tension kills your sequence.”

If you’re too upright or tight in setup, you’re already out of range.
Watch how a simple change in tilt and arm hang transforms the way the club moves — freeing up your side bend, rotation, and sequence.

Coaching with GRF isn’t about positions — it’s about how the body moves with the ground.
Learn how to create space, stay grounded, and let the swing flow naturally.

YOUR SLICE MIGHT START IN YOUR FEET! ⛳️
If you’re constantly slicing the golf ball, you might be trying to fix the wrong thing.
The problem isn’t always your hands or the club.
It’s how your body uses the ground.
Get the pressure moving in the wrong direction and your upper body can take over, sending the club across the ball.
That’s where the Z drill comes in.
Learn to move pressure in the right direction and give your body a better chance to sequence the downswing.
🔥 Still struggling with a slice?

Comment SLICE below and I’ll send you details on how we can identify what’s causing it in your swing and help you build a more repeatable ball flight.

“It’s been revolutionary for my swing.” ⛳️

Sometimes the biggest breakthrough in golf isn’t about adding more swing thoughts. It’s about understanding how your body moves and learning to trust it.

That’s exactly what our golfers experienced at the GRF Golf School.

From rediscovering natural movement to building confidence and taking improvements from the range onto the golf course, hear what they had to say about their experience.

🇺🇸 NOW IT’S YOUR TURN, USA!

Marcus and the GRF team are heading to the USA for our upcoming Golf Schools, giving you the opportunity to experience the GRF approach for yourself.

If you’re tired of inconsistent ball-striking, overthinking your swing or struggling to take your range game onto the course, this could be exactly what you’ve been looking for.

Most golfers are told to “use the ground” — but what are you actually supposed to feel?
This drill gives you the answer.
The towel teaches you how to shift and load the lead side.
The pressure dome teaches you how to push back through the heel and release that energy.
Shift. Push. Squash.
Get the sequence right and the club can freewheel — creating speed without forcing it.
Try this next time you’re at the range. 🏌️‍♂️ by @grf_golf

If your arms are creating the golf swing, your sequence may already be out.
The two balls make this much easier to see.
The lower ball represents the pelvis. The upper ball represents the torso.
When the movement is sequenced correctly, the pelvis leads, the torso responds, and that speed can transfer through to the arms and club.
You’re not trying to swing the club harder with your arms.
You’re trying to create the movement that allows the arms and club to follow.
If your swing feels handsy, disconnected or like you have to force speed, this is exactly the kind of sequencing we look at in a GRF lesson. by @grf_golf

If your strike feels random, your low point probably is too.
This drill gives you a reference for moving the low point forward.
Wedge the trail foot, load into it and feel yourself push away from it.
Then take the ball away.
Learn where the club enters the ground first. Get used to creating the divot in the right place — then introduce the ball and compare the feeling.
You’re not trying to manufacture a position with the club.
You’re giving the body a movement that changes where the club bottoms out.
Control the low point. Control the strike.

Big session back in laboratory of @grf_golf, having only played for 9 months the swing changes constantly & the learning curve is very steep. Really happy with the feels today, time to get the reps in ahead of our big match up… 👀

It goes without saying but if you want to improve your game, speak to Marcus at GRF 🙏 by @grf_golf
