Mobile vs Stable Joints in Golf: Why Unlocking Your Body Can Restore Speed and Eliminate Pain
Mobile vs Stable Joints in Golf
If your golf swing feels slower than it used to…
If your lower back aches after 18 holes…
If your knees stiffen up the morning after a range session…
Here’s the truth:
Your swing probably isn’t getting worse because you’re getting older.
It’s far more likely that some of your joints simply aren’t doing the jobs they were designed to do.
That’s the entire focus of my new Move Better, Swing Faster, Play Longer series on Golf Mad Dad — and in Episode One, we lay the foundations by diving into one of the most important concepts in modern golf biomechanics:

👉 Mobile vs stable joints.
This principle — taught through the Titleist Performance Institute and championed by experts like Dr Greg Rose — completely changed how I understand my own body, my injuries, and my golf swing.
Let’s break it down.
Why Golfers Over 40 Struggle With Pain and Speed Loss
I’m Andy — 46 years old, lifelong sports nut, sports science graduate, newly TPI-qualified… and someone who has chased speed and performance across football, cricket, tennis, and now golf for decades.
And like many of you reading this:
- I’ve had serious injuries (ACL surgery, hamstring rupture)
- I’ve spent years at desks
- I’ve trained hard… sometimes too hard
- I’ve felt that creeping stiffness
- I’ve wondered why things start hurting “out of nowhere”
What I’ve learned?
Pain in one area is often the result of a problem somewhere else.
Your knee might hurt…
…but the cause could be your hip.
Your lower back might flare up…
…but the real issue might be your ankles or thoracic spine.
That’s where mobile vs stable joints come in.
What Are Mobile and Stable Joints?
In simple terms, the body is built around an alternating pattern:
Some joints are designed to move freely in multiple directions.
Others are designed mainly to resist movement and create stability.
Mobile Joints
These like moving in three planes of motion — rotation, flexion/extension, side-bending.
Examples:
- Ankles
- Hips
- Thoracic spine (mid-back)
- Shoulders
- Wrists
Stable Joints
These prefer simple hinge-style movement — flexion and extension — and are there to protect the mobile joints around them.
Examples:
- Feet
- Knees
- Lower back (lumbar spine)
- Scapula (shoulder blade area)
- Elbows
The Body’s Brilliant Symmetry
What really opened my eyes during my TPI education was how perfectly patterned the body is:
- Foot → stable
- Ankle → mobile
- Knee → stable
- Hip → mobile
- Lower back → stable
- Thoracic spine → mobile
- Scapula → stable
- Shoulder → mobile
- Elbow → stable
- Wrist → mobile
When this system is working properly?
✔️ You rotate better
✔️ You generate speed more easily
✔️ You protect your joints
✔️ You stay pain-free
✔️ You swing efficiently
When it breaks down?
That’s when golfers start compensating — and compensation is where pain and swing faults creep in.
How Compensation Creates Swing Faults
Life gets in the way.
Desk jobs.
Old injuries.
Years of sport.
Too much sitting.
Not enough movement.
Mobile joints slowly lose mobility — particularly:
- Ankles
- Hips
- Thoracic spine
- Shoulders
When that happens, the body steals motion from joints that shouldn’t be moving much.
That’s when we see:
- Lower-back overload
- Knee pain
- Early extension
- Reverse spine angle
- S-posture at address
- Chicken wing
- Sway in the backswing
The pain you feel is the fire alarm.
The real fire usually started somewhere else.
How TPI Screening Identifies the Problem
One of the most powerful tools I now use is the TPI movement screen — 15 quick tests that take under 10 minutes and assess:
- Hip rotation
- Thoracic mobility
- Ankle range
- Shoulder function
- Core stability
- Pelvic control
It highlights exactly where your mobility–stability chain has broken.
Even better?
The TPI system now uses AI-driven modelling to predict which swing characteristics you’re likely to show based on your movement limitations.
That’s huge.
It means instead of guessing…
we can measure.
A Real-World Example: Unlocking a Golfer in His Early 40s
Recently I started helping a mate — classic early-40s golfer:
- Desk job
- Tight everywhere
- Knee pain after rounds
- Lower-back flare-ups
- Speed dropping
A few simple tests told the story:
- Locked hips
- Restricted thoracic spine
- Limited shoulder external rotation
In short?
Every major mobile joint in his body wasn’t mobile anymore.
Before even opening the TPI app, I predicted he’d:
- Early extend
- Set up with S-posture
- Show reverse spine angle
- Load his lower back heavily
The screen confirmed it.
The fix?
Not endless swing thoughts.
The priority is:
👉 Restore mobility
👉 Unlock the hips
👉 Free the thoracic spine
👉 Improve shoulder rotation
👉 Re-sequence the body
We’re building a program now, and over the coming months you’ll see his journey on the channel — with the aim of taking him from a mid-teens handicap toward single figures.
How This Helped My Own Knee Pain
I’m not preaching theory here.
A few weeks ago my knee started flaring up again.
Instead of blaming the knee, I went back to fundamentals:
- Hip mobility work
- Glute activation
- Less sitting
- Better daily movement
Result?
👉 Knee pain faded.
The knee wasn’t the problem.
The joints above it were.

If you’ve ever thought:
- “My body won’t let me swing how I’m told.”
- “My speed has dropped.”
- “I’m always tight.”
- “Golf hurts now.”
This series is for you.
Final Thought: Fix the Body, Fix the Swing
If your mobile joints move well…
and your stable joints stabilise…
You swing faster.
You protect your back and knees.
You rotate more freely.
You play longer.
That’s the mission:
Move better.Swing faster.Play longer.
Let’s get that body symmetrical again — and start enjoying golf for decades to come.
