There is an old steam engine sitting in a museum in Birmingham.
Built in the late 1800s. Massive. Impressive. The kind of machine that defined an era.
It also burned through enormous amounts of coal to move a relatively modest load.
By modern standards, it was wildly inefficient.
Not broken. Not poorly designed for its time. Just burning more than it needed to in order to do what it was asked to do.
Modern engines do the same work on a fraction of the fuel.
Same task. Dramatically different cost.
I think about that engine a lot when I watch people walk.
Not because walking is complicated. Because it is supposed to be simple and for a lot of people it has quietly become anything but.
Here is something I notice consistently in my work.
The men and women folk who come to see me are often tired in a way that does not quite add up. They slept reasonably well. Their schedule is not unreasonable. They are not doing anything that should leave them running on empty by two in the afternoon.
But they are.
And when I watch how they move, really watch, the way a biomechanics practitioner watches, the answer is usually right there.
The body is burning more than it needs to.
Not dramatically. Not in a way that shows up on any test or scan. Just, inefficiently. By degrees. In ways that accumulate across every step of every day until the fatigue that shows up at noon has less to do with what happened that morning and more to do with the cost built into every movement since they got out of bed.
That is what this month is about.
Movement Economics.
What Movement Economics Actually Means
Every movement the body makes has a cost.
Not just calories, though that is part of it. The deeper cost is structural. Neuromuscular. The demand placed on the joints, the fascia, the stabilizing system, and the nervous system that coordinates all of it.
An efficient movement spends the minimum necessary to produce the result.
An inefficient movement spends more than necessary.
And the difference between those two things, compounded across thousands of steps and dozens of daily movements determines how much is left over at the end of the day.
Think about fuel economy in a car.
Two vehicles. Same destination. Same road.
One gets forty miles per gallon. One gets fifteen.
They both make the trip.
But one of them stops for gas twice.
The human body works the same way. Two women. Same daily life. Same demands on their time and energy. One of them moves efficiently, her gait is organized, her fascia is transmitting clear signals, her joints are loading correctly. The other moves inefficiently and she is stopping for gas twice before lunch.
The difference is not fitness. It is not effort. It is not age. It is economics.
Why Walking Is the Place to Start
Of all the movements worth examining, walking is the one that matters most.
Not because it is the hardest. Because it is the most repeated.
The average person takes somewhere between five thousand and ten thousand steps a day. Every one of those steps is either efficient or not. Every one of them either draws from the body’s energy budget appropriately or takes a little more than it should.
At five thousand steps, that math adds up fast.
Anthropologists identify walking as one of the four fundamental movement patterns the human body was built around. The skeleton, the gait cycle, the way force travels from the foot through the ankle, knee, hip, and spine, all of it was shaped by hundreds of thousands of years of walking efficiently across varied terrain.
When walking works the way it was designed to, the body essentially bounces itself forward.
The posterior chain absorbs impact and drives propulsion. The arm swing counterbalances the leg swing. The thorax rotates to distribute load across the whole system. The fascia acts as a spring, storing energy on impact and releasing it on push-off.
Almost free. That is what efficient walking costs.
When it is not working that way, when one hip is restricted, when the glutes are not firing, when the thorax has lost its rotation, when the fascia has been bracing so long it has stopped acting as a spring, the body has to work harder to do the same thing.
More muscular effort. More joint compression. More nervous system resources allocated to managing the inefficiency.
Five thousand steps of that. Every single day.
What Gets in the Way
The inefficiencies that make walking expensive do not usually arrive all at once.
They accumulate quietly. Over years. In response to the environments and habits that make up modern daily life.
A hip that spent years in a chair gradually loses its extension range. The glute on that side, which should be one of the primary drivers of the gait cycle, starts to check out. Another structure covers for it. Then another.
A thorax that spent years at a desk gradually loses its rotation. The mid-back that should be counterbalancing the legs with every step becomes rigid. The lower back compensates. The neck compensates.
A foot that spent years in cushioned shoes on flat surfaces gradually loses its sensory responsiveness. The proprioceptive system that should be feeding rich information to the nervous system with every step goes quiet. The nervous system, receiving less information, becomes more cautious. The gait pattern tightens to manage the uncertainty.
None of these things happen dramatically. They just become the new normal.
And the new normal costs more than it should, every step, every day, in ways that never show up on a test but show up reliably at two o’clock in the afternoon.
The Role of the Fascia
Here is the piece that most fitness and healthcare conversations completely miss and the piece that I think is most important to understand. The fascia.
The continuous web of connective tissue running through the entire body is not just structural packaging. It is a spring system. A force transfer network. A communication system that sends signals to every muscle in the body.
When the fascia is healthy, mobile, hydrated, appropriately tensioned it stores energy on impact and releases it on propulsion. Like a rubber band that has been stretched and released. That stored and returned energy is one of the primary mechanisms by which efficient walking costs so little.
This is called elastic energy storage. And it is essentially free movement, energy the body generates from its own mechanics rather than burning from its reserves.
When the fascia is restricted, thickened by chronic stress, dehydrated by inactivity, locked into bracing patterns by years of compensation, it loses that spring quality. It becomes more like a brace than a spring. Energy that should be stored and returned is instead absorbed and lost.
And the muscles, which follow the signals the fascia sends, not the other way around, have to work harder to produce the same result.
More effort. Same output. That is the definition of an inefficient engine. And restoring fascial health does not just reduce pain or improve range of motion. It lowers the cost of movement. It gives the body back the energy it was spending on compensation and makes that energy available for everything else the day requires.
A Story About a Walk
I worked with a woman, I’ll call her Diane.
Sixty-three years old. Retired teacher. Walked forty-five minutes every single morning. Consistent. Committed. By every conventional measure, doing the right things.
She came to me not because she was in pain. She came because she was tired.
Not tired from the walk itself. Tired by the middle of the day. Every day. For years. In a way she could not explain given how much she was sleeping and how manageable her schedule was.
When I watched her walk, the picture was clear within about thirty seconds.
Her right hip barely extended. The glute on that side was doing almost nothing. Her thoracic spine, the mid-back that should rotate with every step to counterbalance the legs, was locked. Stiff from years of desk work and a gait pattern that had never asked it to do anything different.
So her lower back was compensating. Her neck was compensating. Her left side was carrying load the right side should have been sharing.
She was walking forty-five minutes a day. Her body was working as if she had walked ninety.
Not because the terrain was hard. Because the gait pattern was inefficient. Because the engine was burning more than it needed to and had been for years.
We addressed the hip extension. The thoracic rotation. The fascial restrictions along the posterior chain that had frozen parts of her gait cycle in place.
Within a few weeks something shifted.
The afternoon fatigue started lifting. Not dramatically. Gradually. But consistently.
She told me — “I’m doing the same walk. I just don’t feel wrecked after lunch anymore.”
Same distance. Same time. Same woman. Different movement economics.
This Is Not Just About Walking
Walking is the most repeated movement pattern most people perform. That is why it is the place to start.
But the same principle, efficiency determines cost, applies to everything the body does.
Getting up from a chair. Carrying groceries. Climbing stairs. Reaching overhead. Bending to pick something up.
Every one of those movements is either organized or compensated. Either drawing from the right structures in the right sequence or rerouting demand through structures that were never designed to carry it.
And every inefficiency, every compensation, has a price tag.
Most people have been paying that price for so long they have forgotten what it felt like before the bill arrived.
That is what makes this conversation different from most fitness conversations.
Most fitness is about doing more. More reps. More steps. More intensity.
Movement economics asks a different question.
What is it actually costing the body to do what it is already doing?
Because sometimes the answer to fatigue is not more effort.
It is better organization.
Four Signs Your Movement Is Costing More Than It Should
These are not meant to alarm. They are meant to name something that may have been in the background for a while without a clear explanation.
1. You feel more tired after routine daily activity than the activity seems to justify. The walk, the grocery run, the afternoon of errands. If the fatigue level does not match the demand level, the body is spending more than it should to do what it is doing.
2. One side of your body feels noticeably more worked than the other after walking. Soreness or fatigue concentrated on one side is the body telling you the load is not being shared evenly. One side is compensating for what the other is not contributing.
3. Your walking pace has gradually slowed without a conscious decision. The body self-selects a pace that minimizes discomfort given its current movement pattern. A slowing pace is often the body adapting around its own inefficiency — not a sign of aging, a sign of compensation.
4. You feel better after moving than when you started but the improvement does not last. Movement temporarily improves fascial hydration and nervous system regulation. But if the underlying pattern has not changed — the stiffness and fatigue return. The engine resets to its inefficient baseline.
What Better Movement Economics Actually Produces
This is worth being specific about. Because the goal of improving movement efficiency is not just less fatigue — though that is a real and meaningful outcome. It is more life.
More energy available for the walk with the dog. The afternoon with the grandchildren. The trip that requires hours on your feet. The evening that does not have to end early because the body ran out of fuel.
Diane kept walking her forty-five minutes every morning.
But the rest of her day started to open up in ways that had been quietly closing for years.
That is movement economics working in your favor.
Not more effort. Better return on the effort already being made.
