Understand Your Spine

The explanation your tests never gave you. Taught by a chiropractor of 30 years, for people whose back hurts and whose scans came back normal.

By Peter Bennett7 modules

Your scan came back normal. Your back didn't get the memo.

You've had the imaging. It was unremarkable. Maybe a chiropractor gave you a few hours of relief, or a physio handed you a fresh set of exercises each week, and none of it explained why the ache keeps coming back.

I've spent 30 years in clinic watching this exact scene. People who were told their tests were fine, whose bodies kept saying otherwise. The gap between those two things has a name, and nobody taught it to you.

Load versus capacity. Your tests are normal because tests measure structure. They show what your spine looks like. They don't show what it has been carrying, or how much carrying it can currently tolerate. The trouble lives in the gap, and no scan measures the gap.

Seven lessons, and the work that goes with them

A short course that teaches you the model I have used for three decades. Not a list of exercises to memorise. Not a diagnosis. The explanation itself, taught properly, so the next decision about your back is one you understand.

Most lessons end with a worksheet, and the worksheets are where the course stops being reading and starts being yours.

  • Lesson 1, the screening. Six questions that tell you whether this course is safe for you or whether you should see a doctor today. It comes first for a reason.
  • Lessons 2 and 4, the load audit. Not a symptom diary. A ledger of what your spine has actually been carrying, across four kinds of load, including the ones nobody counts.
  • Lesson 3, the two dials. Load and capacity, worked out on paper, until you can explain it to a friend in two sentences.
  • Lesson 6, the dose and the log. You take a baseline number, learn the one rule that decides whether a movement is right for you, and build a fortnight of evidence. Plus a bad-day protocol for when it flares.
  • Lesson 7, what can change. The honest split between what's fixed and what's yours to build.

The rule that keeps you safe from yourself

Most back advice fails people in the same way. It gives them something to do, and then nothing tells them when to stop.

So lesson 6 gives you a test you can apply alone: a movement is inside your tolerance if you could do it again tomorrow, at the same amount, without bracing, and without paying for it that evening. If you have to hold your breath, tighten everything, or spend the evening recovering, it was too big.

Halve it. Restart at the amount that was easy, not at zero. And when a weekday gets heavy, the dose goes down, not up.

There is no list of safe exercises, and no progression you have to keep up with. There is a dose, and a way of reading your own body that makes the dose obvious. That is what you leave with.

The part most courses don't have: you can ask it back

This is a course with a tutor that has read every lesson and knows the model.

At 11pm, when your back has flared and last Tuesday's lesson has gone blank, you don't have to wait for a Monday appointment. You ask. It answers in plain words, pulls up the lesson you need, and explains the bit you didn't follow.

It also knows where you are in the course. It asks which lesson you're on, answers from there instead of dumping everything at once, and keeps you moving at a pace you can hold.

And it will slow you down. Ask it for a programme, ask how fast this works, tell it you pushed through the pain, and it will send you back to the rule above and to your own worksheet. Doing more is the risk here. It is what put most people on this page to begin with.

Two things it will never do. It won't tell you what is wrong with your back, and it won't diagnose you. It teaches principles. If you need a personal read on your own spine, that is a conversation with a human being, and it will say so.

Why a chiropractor is telling you this

I could sell you a block of appointments. This page would be longer and I would make more money. I've been in practice long enough to know that the thing that changes someone's relationship with their back is not the technique, it's finally understanding the mechanism.

So this is the explanation I give across a desk, made portable, with the same care about how much you take on and how fast. It doesn't compete with hands-on care. It sits under it. Some people finish it and manage their own back. Some finish it and know exactly what to ask a practitioner for, including me. Both are good outcomes.

I don't promise you an outcome and you should be sceptical of anyone who does. Loading history matters, too much load and too little both cause harm, and a spine's tolerance for load is changeable. That is what the evidence supports and that is what I teach.

Who this is for

You've had the tests. You've had the advice that didn't stick. You've started to half-wonder whether it's just your age, or in your head. It isn't. It is usually load you were never taught to see.

You don't need to be in agony to get value here. A stiff back that comes and goes, a mild niggle after sitting, or simply wanting to understand your own body before something goes wrong, all belong here. It suits someone between episodes, calm enough to read and angry enough to want the explanation.

It is not for you if you are in acute severe pain, have neurological symptoms, or are waiting on a diagnosis. Read the red flags first. Get seen.

What it costs

£97 once. Seven lessons, worksheets that build into a fortnight of your own evidence, a tutor that answers questions any hour you need it, and it is yours permanently. No subscription, no renewal, no discount that expires this weekend.

That is roughly the cost of two clinic appointments. The difference is that this one explains itself, and you keep it.

What this is

This is a course you can talk to.

The lessons are here, and you can read them like any course. But the AI has read all of them too. When something doesn't click, ask. When you're not sure how it applies to you, ask. It answers from Peter Bennett's material, not from the internet. It's like hiring Peter Bennett as a coach, without paying thousands of dollars for it.

What actually builds capacity in a spine?

Understand Your Spine

Good question. Here's what Peter Bennett teaches about that, and how it fits what you're doing.

This is how learning works now. You don't watch and forget. You ask, you get an answer for your situation, and you use it. That's what makes it stick.

What you can ask

  • What actually builds capacity in a spine?
  • I was told to push into the pain. Is that right?
  • How do I know if a movement is within my tolerance?
  • Why does resting make my back worse?

About Peter Bennett

Peter Bennett

Dr Peter Bennett BSc DC spent 30 years in clinic as a chiropractor, most of it with people whose tests came back normal and whose bodies disagreed: the desk years, the difficult years, the recovery they never got round to. His method is subtraction rather than addition. Where most back advice hands you more stretches to remember and more fear to carry, he explains the mechanism instead: what load is, what capacity is, and why the gap between them is where the trouble lives. People arrive having been told nothing is wrong, or that they'll have to live with it. They leave able to make their own decisions.

Questions

What exactly do I get?

Seven written lessons that teach the load-versus-capacity model, a worksheet at the end of most of them, and a tutor trained on all of it. You can read the course in an afternoon, and the worksheets then run over the following fortnight. It's yours to revisit any time.

What are the worksheets?

Lesson 1 screens you. Lessons 2 and 4 make you audit what your spine has actually been carrying. Lesson 3 gets load and capacity down on paper. Lesson 6 sets a baseline number, a dose, a two-week log and a bad-day protocol. Lesson 7 separates what's fixed from what can change. They are short, and they are where the course does its work.

Is this a treatment or a diagnosis?

No, and I want to be precise. This is education about the principles of spinal health. It is not a diagnosis and it is not treatment of any specific condition. It works alongside hands-on care and never replaces it. If you need an examination, see a practitioner in person.

Are you prescribing exercises?

No. I teach the principle of dosing, and a rule you apply yourself: could you do this again tomorrow, same amount, without bracing, without paying for it that evening. What you choose to move is yours to judge. Nobody can prescribe for a body they haven't examined, and I won't pretend otherwise.

Is it safe if my back is bad right now?

The first lesson is a six-question screening, and if anything on it rings true the answer is see a doctor today, not read another lesson. The course is written for the common, non-dangerous majority whose scans came back normal.

Will the AI tell me what's wrong with my back?

No. It teaches the principles and answers questions about them. It won't diagnose you, interpret a scan, or tell you what to do about a specific symptom. That boundary is deliberate, and it's in the first lesson.

What if I'm doing too much?

It will tell you. Ask it for a programme, say you pushed through the pain, or ask how fast this works, and it will take you back to the tolerance rule and to your own worksheet. The course is built to stop you overshooting, because doing more is what usually caused the problem.

Are you trying to replace my chiropractor or physio?

The opposite. Most of the people I've treated over 30 years spent the first appointment confused about what was happening to them. If you understand the mechanism, the care you get goes further and you can tell good advice from a sales pitch.

Do I need to be in pain to get value from this?

No. It's for anyone with a stiff back that comes and goes, mild recurring symptoms, or who simply wants to understand their own spine before something goes wrong.

Is there a subscription?

No. £97 once, and it's yours. No renewal and no monthly charge.

If I finish and still want hands-on help, what then?

The course tells you what to look for, which questions to ask, and how to tell a practitioner working to a plan from one selling you a block of appointments. There's no obligation to see me, and nothing in here is a funnel into my clinic.

What if it doesn't help?

Work through the course and the worksheets. If it doesn't clear anything up for you, tell me and I'll refund you. No forms, no fuss.

Refunds

If you work through the course and it doesn't clear anything up for you, tell me and I'll refund you. No forms, no fuss. The same promise I'd make across a desk.
