The six principles of Pilates are centering, concentration, control, precision, breath and flow. They describe how every Pilates exercise should be performed, whether on a mat or on equipment such as the reformer. Joseph Pilates did not publish them as a numbered list. Later teachers and authors drew them from his teaching and writing, and the six-principle framework was popularized in the 1980 book by Philip Friedman and Gail Eisen, The Pilates Method of Physical and Mental Conditioning.
This guide explains what each principle means, how to apply it in a session, how the principles work together and the mistakes that make Pilates less effective.
Where the principles come from
Joseph Pilates called his method Contrology, which he described as the complete coordination of body, mind and spirit. In his 1945 book Return to Life Through Contrology, written with William John Miller, he stressed deliberate, controlled movement, full breathing and whole-body attention. His students, often called the first-generation teachers or elders, passed on these ideas in slightly different ways.
That is why you may see lists with more or fewer principles, or different names. Some schools add ideas such as alignment, stamina, relaxation or whole-body movement. The six listed here are the most widely taught version and cover the core of the method.
The six principles at a glance
| Principle | What it means | In practice |
|---|---|---|
| Centering | Movement begins from the core, often called the powerhouse | Engage the deep abdominals, back, hips and pelvic floor before moving the limbs |
| Concentration | Full attention on each movement | Think about alignment and which muscles are working, not about counting reps |
| Control | No momentum-driven or sloppy movement | Move slowly enough that you could stop at any point in the exercise |
| Precision | Each movement has a correct position and path | Do fewer, exact repetitions rather than many loose ones |
| Breath | Full, coordinated breathing | Breathe laterally into the ribs and usually exhale on the effort |
| Flow | Smooth, continuous movement and transitions | Link exercises gracefully without collapsing between them |
Each principle explained
Centering. Centering means that movement starts from the trunk. The powerhouse usually refers to the muscles between the lower ribs and the hips: the deep abdominals, the back extensors, the glutes and the pelvic floor. When these muscles stabilize the trunk, the arms and legs can move efficiently without strain on the lower back. In practice, you set the core before each movement rather than letting the limbs lead.
Concentration. Pilates asks you to pay attention to how you move, not just whether you finish the exercise. Concentration means noticing where the pelvis sits, whether the shoulders creep up and how the spine moves. This mental focus is what separates Pilates from mindless repetitions, and it helps build body awareness that carries into daily life.
Control. Joseph Pilates named his method after control. Every movement should be deliberate, with no swinging or throwing the body through a range. A good test is whether you could pause at any point in the exercise. Control protects the joints and makes the muscles do the work rather than momentum.
Precision. Each Pilates exercise has a specific starting position, path and finishing position. Precision means doing the movement exactly, with correct alignment, rather than approximately. Instructors often prefer five precise repetitions to fifteen careless ones, because precise work builds better movement patterns.
Breath. Pilates emphasized full, deep breathing. Many teachers use lateral or thoracic breathing, where you breathe into the sides and back of the ribcage while keeping the abdominals engaged. A common pattern is to exhale on the effort phase of an exercise, although specific breathing patterns vary between exercises and schools.
Flow. Flow is the smooth, rhythmic quality of movement, both within an exercise and between exercises. In the classical mat sequence, one exercise leads into the next with minimal breaks. Flow develops naturally as the other principles become automatic.
How to apply the principles in a session
- Set up before you move. Check your alignment and engage your center before starting each exercise.
- Pick one principle to focus on. Beginners often find it easier to concentrate on one principle per session, such as breath or control.
- Slow down. Moving slowly exposes weak points and makes control and precision possible.
- Coordinate breath and movement. Match the breath to the rhythm of the exercise instead of holding it.
- Reduce range if needed. A smaller, controlled movement is better than a larger one that loses form.
- Work with a qualified instructor. Feedback on alignment is especially useful when learning the method.
How the principles work together
The principles are not separate checklists. Centering gives the body a stable base, concentration keeps attention on form, control and precision shape each movement, breath supports the effort and flow ties it all together. When one slips, the others usually suffer. Holding the breath, for example, often leads to tension and loss of control, while losing concentration often leads to sloppy alignment.
The same principles apply across all forms of Pilates, from classical mat work to reformer, Cadillac and chair exercises. Contemporary Pilates styles may adjust the exercises for rehabilitation or athletic training, but they still rely on these ideas.
A simple exercise to feel all six principles
The pelvic curl is a good way to practice the principles together. Lie on your back with knees bent, feet hip-width apart and arms by your sides. Inhale to prepare and set your center. Exhale as you tilt the pelvis and peel the spine off the mat one segment at a time until you rest on the shoulder blades. Inhale at the top, then exhale as you roll down through the spine with the same control. Focus on precise spinal articulation, steady breathing and a smooth rhythm across five to eight repetitions.
This one movement shows centering, concentration, control, precision, breath and flow in a way beginners can feel right away.
Common mistakes
- Rushing through repetitions. Speed usually replaces control with momentum.
- Holding the breath. Breath-holding raises tension and makes movements harder to control.
- Over-gripping the abdominals. Centering does not mean clenching as hard as possible. It means steady, appropriate engagement.
- Chasing range over form. Pushing for a bigger stretch or higher leg often breaks alignment.
- Counting instead of feeling. Focusing on the number of reps pulls attention away from how the movement feels.
- Treating flow as speed. Flow means smooth movement, not fast movement.
Health note
Pilates is generally low impact, but some exercises load the spine, neck and shoulders. If you are pregnant, recovering from injury or surgery, or have back pain, osteoporosis or another medical condition, check with a doctor or physiotherapist before starting and work with an instructor who can modify exercises. Stop any movement that causes sharp pain. This article is general information and not medical advice.
Frequently asked questions
Did Joseph Pilates create the six principles?
Not as a formal list. The principles come from his teaching and writing, and they were organized into six by later authors, most notably Friedman and Eisen in 1980.
What is the most important Pilates principle?
Many instructors start with centering because a stable core supports every other movement, but the principles work best together rather than in isolation.
Do the principles apply to reformer Pilates?
Yes. Centering, concentration, control, precision, breath and flow apply to mat and equipment work alike, including the reformer, Cadillac and chair.
