Maybe it was yet another therapist that focused only on the point of pain.
02
Exercises, no explanation
Maybe you were handed a sheet of exercises with no clear explanation of why.
03
Rested, then it came back
Maybe you were told to rest, it felt better, and then it came back the moment you started moving again.
Nothing found?
Or maybe nobody's found anything at all. Scans clear, tests fine, still not right.
Why it keeps coming back
The place it hurts is often just where years of asymmetry have ended up. It's usually not where the problem started.
Not only about pain
Plenty of people come in because they've plateaued, or because something in their training keeps breaking down and they can't work out why. It's the same assessment either way, because it's answering the same thing...
How is your body functioning, and why?
Four reasons
Why get a biomechanical analysis?
1
Break the pain cycle
The same problem for months, maybe years. You know what it is, but nothing seems to help. We take a look from every angle.
2
Improve performance
You're training hard but still not improving. Something is holding you back and you can't work out what. You need clear focus where it's needed.
3
Slow the ageing process
You want to still be physically capable in twenty years, not deteriorating month after month. We focus on what you can do, not what you can't.
4
Prevent future issues
Nothing might hurt just yet. But asymmetries build up in the background over the years. Prehab before rehab, so you keep doing the things you love.

T · Step 1 of 5
Talk
What your body has been through
We always start with a conversation. Injuries, past and present. Surgeries. The things that came back no matter what you tried. Then we talk about your actual life: work, sleep, stress, training load, what your body does every day and what you may not be doing.
Physical load and psychological load both affect the body, and they tend to show up in similar places.
I'm looking for patterns, not a list of complaints. What comes out of this is as much about what you should stop doing as what you should start.
R · Step 2 of 5
Read
What your posture shows me
Before you move, I observe how you hold yourself. Where your centre of gravity lies. How your pelvis sits, the level of your shoulders, even right down to a patch of hard skin on the inside of a foot.
None of it is random. Every part of you is a telling part of the story.
Uneven wear on a tyre isn't a tyre problem. It's telling you the alignment is off. Replace the tyre and you'll be back in six months with the same wear in the same place.
A · Step 3 of 5
Assess
How you move, and where you're uneven
Squat, lunge, push, pull, walk, run. These aren't gym exercises, they're the functional movements of everyday life. You do them hundreds of times a week without thinking, and if you're doing them inefficiently, that inefficiency is repeated thousands of times until something breaks down.
Movement is also where your asymmetries show themselves. Nobody is symmetrical. A weakness in the outer hip can surface as pain on the inside of the shin. Every step sends load through the chain, and if your movement habits are dysfunctional through injury, fear or poor mechanics, you're reinforcing that pattern every time you move.
A single movement can tell me a lot about how you got here, and how your body would hold up under the repeated stress of everyday life.
C · Step 4 of 5
Check
A deeper dive
Six principles of fitness make up how a body performs: strength, power, flexibility, mobility, balance and endurance. Almost everyone I see has built one or two of these and let the rest fade into the sunset.
So we check them properly. Range of movement in every joint. Strength on both sides, alone and then together. Your balance, and then a conversation about your aerobic fitness and loading strategies.
We aren't scoring you. We're putting it all on the table, to find out which of these you've been missing and where you need to place your focus.
K · Step 5 of 5
Know
A clear picture
I'm not handing you a sheet on the way out and telling you to crack on. I take all of it, the history, the observations, the screening, the tests, and create a clear picture. Patterns that go unnoticed tend to show themselves when you sit back and take a deeper look.
You'll receive a written breakdown that explains what I found, what it means, and exactly what to do about it.
The thing you couldn't work out on your own, you now understand.

The guarantee
Complete the sessions, do the work I set you, and if we re-test at the end and nothing has improved, you get your money back. The re-test uses the same markers as your first assessment, so it isn't a matter of opinion.
Different starting points
The same first step.
Three very different people. Three different problems. Each one began with the same assessment.
Brian
25 years of back pain
TRACK Assessment
Rebuild Focused
Pain cleared, sleeping better
★★★★★I'd had problems with my back for the best part of 25 years. Chiropractors, massage, painkillers, you name it, I'd had it. Four weeks in, my pain has as good as cleared completely, and my flexibility is better now than when I was a teenager. My only regret is that I never discovered this earlier.

Weekly 1-1 + App Plan
Back hiking pain-free
★★★★★I applied for the full reset hoping he could solve a longstanding back, hip and knee issue that was escalating to pain when I was hiking. He quickly identified the issues and designed a bespoke plan, no one size fits all with Stephen. The day I realised my hip was no longer hurting was a revelation. My favourite pastime is once more enjoyable.

Everest Base Camp
★★★★★I came in wanting my body ready for something I'd never asked it to do. The assessment found what I needed to work on, and everything after was built around that one goal. Seven months later I was standing at Everest Base Camp.

The person assessing you
Stephen Jack BSc (Hons)
For years I worked as an Exercise Rehabilitation Instructor in the Army's Regional Rehabilitation Units, alongside specialist musculoskeletal teams. I led three-week residential courses for spines, upper and lower limbs, assessing patients and building individual programmes to get them back to full function. Special Forces, UK athletes, soldiers who had to be operational again.
I was Head of Strength and Conditioning for the Army Triathlon Team, running the testing and programming that took athletes to victory in the inter-services competitions.
Underneath this is a First Class Honours degree in Strength and Conditioning, a specialised Exercise Rehabilitation Instructor qualification, and a deep understanding of the body built over 20+ years in this field.
When I assess you, I'm drawing on twenty years and thousands of bodies, from soldiers to first-timers who'd never set foot in a gym.

No. Most people who come haven't exercised properly in a long time, and plenty have never done anything structured. The assessment meets you exactly where you are. There's nothing to prepare and nothing to prove.
Do I need to be injured to come?
No. Some people come with a specific problem, some come because something feels off and they can't name it, and some just want to understand their body before it becomes a problem. All three are the right reason.
Can I still come if I'm seeing a physio, or waiting on one?
Yes. This works alongside physio, not instead of it. If you're mid-treatment or waiting for an appointment, the assessment still gives you a full picture of how your whole body is moving, which is often the part a physio doesn't have time to look at.
Can I come if I'm recovering from surgery or an injury?
It depends on where you are in recovery, so message me first and we'll talk it through honestly. If you're too early or you need medical clearance, I'll tell you straight and we'll wait until it's right.
I have a health condition. Will the assessment be adapted?
Yes. Whether it's hypermobility, ME, fatigue or anything else, the assessment and anything that follows is built around you and what your body can safely do. If there's a movement that isn't right for you, we don't do it. Tell me beforehand and I'll plan around it.
How is this different from a physio assessment?
A physio usually focuses on the injury and the area around it. I look at how your whole body moves as a system, because the place it hurts is often just where the problem has ended up, not where it started. Different job, and they work well together.
Is there any risk in the assessment?
It's a low-risk assessment built around what you can comfortably do. Nothing is forced, nothing is pushed to failure, and you're in control throughout. If something doesn't feel right, we stop.
What if you can't help me?
Then I'll tell you, and I'll point you to who can. This is exercise rehabilitation, not diagnosis. If something needs a doctor or a physio first, you'll hear that from me at the assessment. You won't be guided towards something that isn't right for you.
