Here is a scenario that confuses a lot of people. A client begins a new exercise programme. In the early weeks they are burning significant calories, getting out of breath quickly, feeling the effort in their muscles. After several months, the same programme feels noticeably easier. Their breathing recovers faster. The effort feels lower for the same work. They assume they are getting fitter — and they are right. But something else is also happening, something that works against them if they do not understand it, and that most fitness advice never addresses directly.
They have become more efficient. And efficiency, in movement, is simultaneously the goal and the problem.
What Efficiency Actually Means in Movement
In engineering, efficiency means doing more work with less energy. A more efficient engine produces the same output for lower fuel consumption. In movement, the same principle applies: a more skilled, more practised mover uses less metabolic energy to produce the same physical output. Their nervous system has optimised the motor programme. Unnecessary muscle co-contractions have been eliminated. Timing has been refined. The movement has become economical.
This is, in almost every context, desirable. A more efficient runner covers distance with lower oxygen cost and reduced injury risk. A more efficient swimmer produces more speed from the same power output. A more efficient carpenter swings a hammer with less shoulder fatigue over a day's work. Efficiency is the product of skill, and skill is worth acquiring.
But economy has a cost that is rarely named: when a movement becomes fully efficient, it stops being a sufficient stimulus for adaptation. The body has solved the problem. The neural programme is optimised. There is no new challenge requiring a new response. And a biological system that is not being challenged is not being maintained — it is beginning, slowly, to reduce investment in the capacities it no longer needs.
"The beginner's gait is metabolically expensive because it is inefficient. That inefficiency is not a flaw — it is the stimulus. The expert's gait is economical because it is refined. That economy is not a ceiling — it is a new starting point. The question is always: what comes next?"
The Journey — Four Stages That Most People Never Complete
The Postural and Phasic Distinction — Why This Matters for How You Train
Underneath the efficiency paradox sits a more specific problem that affects the vast majority of people who exercise regularly without clinical movement assessment: the confusion between the muscle systems designed for effort and the muscle systems designed for support.
The phasic muscles — the rectus abdominis, the hip flexors, the hamstrings, the upper trapezius — are designed for movement and effort. They are strong, fast, and fatigue-prone. They respond to loading by shortening. They are already, in most desk-working adults who exercise in conventional ways, overdeveloped, chronically shortened, and dominant.
The postural muscles — the deep spinal stabilisers, the multifidus, the transversus abdominis, the gluteus medius, the deep hip rotators — are designed for continuous low-level endurance support. They are not designed to be trained like phasic muscles. They do not produce visible definition. They do not generate the burn that most people associate with effective exercise. And in most adults — including most active adults — they are long, weak, and functionally inhibited.
The conventional exercise approach — more load, more intensity, more volume applied to movements the phasic system already dominates — produces more of what is already excessive and none of what is actually missing. The person who squats heavy but cannot balance on one leg for 30 seconds. The person who planks for two minutes but cannot walk without their pelvis tilting. The person who runs marathons but cannot sit on the floor and stand back up without using their hands. These are not edge cases. They are the expected outcome of training that chases performance metrics without assessing movement quality first.
The efficiency paradox applied to the phasic/postural distinction: The phasic muscles have become highly efficient at doing the postural muscles' job. This is a compensation pattern — and compensation patterns are efficient in the short term and damaging in the long term. The back pain, the hip impingement, the shoulder dysfunction that appears seemingly from nowhere after years of training is often the long-term cost of an efficiency that was never meant to be there.
For the Performance Goal — When Inefficiency Needs to Return
There is a specific point in an athlete's development where efficiency, having been achieved, needs to be deliberately disrupted. Not abandoned — disrupted. A new constraint introduced that makes the efficient pattern temporarily insufficient and forces a higher level of organisation.
The distance runner who has optimised their gait for a flat road has become efficient at flat road running. Introduce trail running — uneven surfaces, unpredictable foot placement, varied gradients — and the optimised programme is suddenly inadequate. The nervous system is challenged again. Proprioception is stressed. The intrinsic stabilisers that the flat road gait had largely bypassed are recruited again. The inefficiency is back — and it is producing adaptation.
This is the principle behind the best athletic development: progressive destabilisation of established patterns to force higher-order organisation. Not random variation for its own sake, but deliberate introduction of novel demands that cannot be solved by the existing motor programme. The pattern that was the answer becomes the question.
The Practical Question — Where Are You in the Journey?
Everything above reduces to a single practical question that determines what your training should look like right now:
The answer determines whether you need more challenge, different challenge, or — most commonly — a step back to the quality of movement before the quantity of load. This is what Move Well First means in practice. Not that load and intensity are unimportant. They are essential — at the right point in the journey. The point is knowing where in the journey you actually are, rather than assuming that because you have been exercising for years you have progressed through the earlier stages.
Many people who have been training for a decade are, in terms of postural muscle function and movement quality, still at stage one. They have become very efficient at compensatory patterns. The efficiency is real. The adaptation it represents is not the one they need.
The Summary — Three Rules
Rule one: Inefficiency is productive when it represents genuine motor learning — new patterns, underdeveloped systems, unfamiliar demands. This is where the most rapid adaptation occurs. Do not rush through it by adding load before quality is established.
Rule two: Efficiency is the goal for functional health — economical, sustainable, injury-resistant movement that supports life rather than merely performing well in a gym. Get here and stay here for general health. For most people this is further away than they think.
Rule three: Economy without challenge is decline. Once a pattern is fully established and no longer producing adaptation, the stimulus needs to change — not necessarily more load, but different demand. Novel environments, unfamiliar movement patterns, proprioceptive challenge, the deliberate introduction of instability that the optimised programme cannot immediately solve.
The journey is not linear and it does not end. The paradox — that the goal of efficiency contains within it the seeds of its own obsolescence — is not a problem to solve. It is the nature of a biological system that exists by adapting. Stop giving it something to adapt to and it stops adapting. Which is, in the end, the simplest possible argument for Move Well First: before you pursue efficiency, establish quality. Before you add challenge, ensure what you are challenging is worth developing.
Movement assessed before it is loaded. Quality established before quantity.
The Move Well First programme works through the foundational movement patterns — breathing, posture, gait quality, postural muscle activation, and progressive loading — in the sequence that the physiology requires. Not the sequence that produces the best before-and-after photos.
