How I Use the Six Principles of Pilates in My Teaching

Spend any time reading about Pilates and you will encounter the six principles: centering, control, concentration, precision, breath, fluidity. They appear in books, studio brochures, instructor training programmes, and introductory articles across the internet. They are presented as the foundation of the method.

I want to write about how I actually use these principles in the work I do with clients, because the experience of being taught with them at the centre of attention is different from the experience of reading about them as concepts. Before that, one piece of context worth knowing.

Where the Principles Came From

Joseph Pilates never wrote them. The six principles were codified after his death in 1967, by teachers and writers working to systematise and explain the method for wider audiences. They are not in his two books — Your Health (1934) or Return to Life Through Contrology (1945). They emerged later as a teaching framework, developed in good faith to make the method easier to communicate.

This does not make them wrong. As qualities to cultivate during practice, they are genuinely useful, and I work with them in every session. But they are not what makes Pilates distinctive. Apply these six qualities to yoga, to dance, to swimming, to any well-taught movement discipline, and you will find them present. They describe good movement practice in general. What separates Pilates lies elsewhere — and I will come to that further on.

How I Use Each Principle in a Session

Control. This is the principle the method is built around, and it is the one I return to most often during a session. The goal of every exercise is efficiency of movement rather than fatigue or exertion. Joseph Pilates wrote that the method teaches you to be in control of your body and not at its mercy. When you work on the apparatus with me, you control the springs — they do not control you. If a movement is being driven by the springs, the work is not yet what it should be. We slow down, simplify, and rebuild until the body is leading and the springs are responding. Movement without control produces compensation. Movement with control produces change.

Concentration. What I am asking of you in a session, beyond the physical work, is genuine attention to what your body is doing. Not just during the movements but during the transitions between them. This is harder than it sounds — most people are not used to sustaining that quality of attention for fifty-five minutes, and it takes time to develop. An hour of real concentration on the body is itself valuable, separate from whatever physical change accompanies it. I cue toward this throughout the session, but the real development of concentration happens slowly across months. The capacity to attend deepens with the practice.

Centering. All movements originate from the centre of the body. The centre is not the stomach. It is the entire region from the base of the sternum to the knees, including the deep layers of musculature that connect and stabilise the trunk, hips, and pelvis. Even movements that appear to involve only the arms or legs require the centre to be stable and organised. When I cue you during footwork, I am not just cueing the legs — I am cueing the centre that holds the legs in productive relationship to the rest of you. There is also a literal dimension to centering that I attend to in every session: are you actually centred on the apparatus? Symmetrically positioned? Evenly weighted on both sides? These are basic but easy to miss, and the work that follows depends on them being right.

Precision. Every movement has a purpose. Every placement of the body matters. Joseph Pilates wrote that a few well-designed movements, precisely performed in a balanced sequence, are worth hours of doing sloppy calisthenics or forced contortion. Precision is not perfectionism. It is intentionality. When I cue you to lengthen the back of the neck during footwork, the cue is not decoration — it is asking for a specific organisation of the head over the spine that changes how the entire exercise works. The cue would be wasted on a body that was just going through the motions. Precision is what makes the cue land.

Breath. The breath is woven into every movement. Conscious breathing supports the direction of the effort, focuses your attention, and helps release tension that accumulates in the muscles. Joseph Pilates wrote, simply, "above all, learn how to breathe correctly." The first thing I observe when you arrive at the studio is how you are breathing at rest, before any instruction has been given. That observation tells me a great deal about how the nervous system is organised, and it shapes how I introduce breath cueing across the early sessions. Breath is also diagnostic across the work — held breath signals over-effort, shallow breath signals tension, and the quality of the breath is often the clearest indicator of whether an exercise is currently within or beyond your capacity.

Fluidity. Movement should be dynamic and graceful, and the transitions between exercises should be as deliberate as the exercises themselves. A well-conducted session maintains a continuous thread of movement and attention from start to finish — the end of one exercise flowing into the setup of the next, no abrupt stops, no breaks in the quality of attention. The more each part of a movement is threaded into the next, the deeper the practice becomes. This is one of the things that distinguishes a private session from a group format. There is no clock for me to follow, no script for the room. The pace can match what your body is doing today.

The Principle the Standard List Omits

There is a principle that does not appear in the standard six but which I find essential to how the method actually works: opposition.

In every exercise there is a mover and a stabiliser. It is never only about where the body is going — it is equally about what is holding it back. In the Twist of Stomach Massage, the rotation happens against the stabilisation of the opposite side. In Elephant on the Reformer, working against rather than with the springs creates the demand the exercise is designed to produce. A stretch in Pilates is always two-directional — the stretch is only as good as its opposition. When I cue you in any exercise, opposition is what I am usually attending to: where the resistance is, what is providing it, and how your body is organising itself against it. That awareness gives me the road map for what to refine and how.

The Principles Are Present from the First Session

One thing worth understanding about these principles is that they are not staged across your training. You do not have to wait for some advanced level before they apply. Centering, control, concentration, precision, breath, opposition — all of them are present and required from the very first exercise in the very first session.

A new client doing Footwork is already being asked to centre, to breathe, to work with precision, to control the carriage rather than be moved by it. The cueing in that first session is at a level appropriate for a body that has not done this work before, but the principles are not held in reserve. They are the quality of attention being brought to the work from the beginning.

This matters for what to expect. The first session will not feel like a workout in the gym sense. It will feel quieter and more attentive. The work is happening at a level that is not always visible from outside. The principles are why.

What Actually Separates the Method

The genuine distinction of Pilates is not captured by the six principles. It lies in something more specific to how Joseph Pilates designed the work.

Pilates is, as far as I understand it, the only exercise system that delivers stretching and strengthening simultaneously — not alternately, not in separate phases, but as a single coordinated action at any moment in the work. You do not hold a posture to stretch and then perform repetitions to strengthen. The mechanism is built into every exercise.

This is possible because of how the method uses what might be described as a strong centre with dynamic two-way stretch — opposition forces working through the body simultaneously, with controlled spinal positions that integrate flexion, extension, and rotation into coherent movement patterns rather than isolating them. The engagement of the centre and the position of the spine are not separate considerations. They are a single integrated action. That integration is what the method trains.

Why the Apparatus Matters Here

Consider Teaser. It can be performed on the Reformer, the Cadillac, the Wunda Chair, the Spine Corrector, and the Mat. The same exercise, across five pieces of apparatus, each placing different demands through different forms of resistance and support.

Why would Joseph Pilates design it this way? Because each apparatus develops a different aspect of the same movement quality. The Reformer provides support that allows the pattern to be learned. The Chair demands stability with minimal assistance. The Mat requires the body to generate everything from within. The exercise is the same. The demand changes. The body develops comprehensively.

This is what the complete apparatus system is for — not variety for its own sake, but a carefully constructed environment in which the same movement qualities can be developed from multiple angles and at multiple levels of demand. The principles I have described above are present in all of them, but the particular emphasis shifts. The principles do not change. The conditions under which they are practiced do.

The Sequence Itself Is the Curriculum

The method has a clear internal logic, and you can see it most plainly inside a single series. Consider the Short Box series on the Reformer. It moves through the spine one plane at a time. The round back is flexion. The flat back is extension. The side bends are lateral flexion. The twist is rotation. The side sit-up then returns to lateral flexion, but working the whole chain from head to heel rather than isolating the spine. And the Tree, last, combines what came before into a single coordinated movement.

Laid out this way, the series is not a list of separate exercises. Each movement isolates one thing the spine can do, so the body learns that plane of motion clearly on its own. The later movements then ask the body to combine them. By the time you reach the Tree, you are not meeting flexion or rotation for the first time — you are integrating capacities the earlier movements have already built. One movement complements the next, and the order is doing the teaching. That is what I mean when I say the sequence is not decorative. It is the curriculum. How the work is arranged is itself instruction in how the body's own parts relate.

What This Means for Your Practice

If you practice with me, the principles I have described will not appear as an explicit syllabus. I will not announce them at the start of a session or test you on them. They will be present in every cue, every adjustment, every choice of which exercise to introduce when. Over months, your body will start to recognise them not as concepts but as the quality of attention the work asks for. That recognition is one of the deeper things long-term practice produces.

The principles describe how the method is practiced. The architecture of the method — the apparatus, the sequencing, the integration of stretching and strengthening, the relationship between the centre and the spine — describes what the method actually is. Both layers are at work in every session. The first layer you will feel from the beginning. The second layer reveals itself slowly across years. That is the work. That is what I am here to teach.
