A note on attribution: The six principles below (concentration, control, centering, precision, breath, and flow) were codified by Joseph Pilates' students and successors as a framework for teaching the method. Pilates himself wrote about these ideas throughout his work, particularly in his books Your Health (1934) and Return to Life Through Contrology (1945).
Concentration
Joseph Pilates insisted that the mind must be fully engaged during every exercise. Unlike many forms of exercise that can be performed mechanically while the attention is elsewhere, Pilates requires continuous mental presence. This isn't incidental: it's the mechanism through which the nervous system learns new movement patterns. Concentration is what separates Pilates from calisthenics.
Control
The original name of Pilates was 'Contrology'the study of control. Every movement is performed with deliberate muscular control rather than momentum, gravity, or habit. This is why Pilates exercises are typically slow: speed allows sloppiness; control demands precision. When you control a movement, you train the muscle fibres, connective tissue, and neural pathways simultaneously.
Centering
Pilates identified the centre of the body (the area between the lower ribs and the hip bones, encompassing the deep abdominals, pelvic floor, and spinal stabilisers) as the origin of all movement. He called it the 'powerhouse.' Every exercise, on the mat or the reformer, initiates from and returns to this centre. Developing awareness of and strength in the powerhouse is the defining physical goal of the method.
Precision
In Pilates, how you do something matters more than how many times you do it. A single precisely executed leg circle develops more than ten sloppy ones. Precision means performing each movement exactly as it is designed: correct alignment, correct breath, correct range of motion. This is why the method scales beautifully: a beginner's precise ten repetitions and an advanced practitioner's precise ten repetitions produce proportionally equivalent results.
Breath
Joseph Pilates considered the breath the most fundamental aspect of the method. His system uses lateral thoracic breathing, expanding the ribcage sideways and to the back, to oxygenate the blood while maintaining core engagement. Inhaling typically prepares for or accompanies movement; exhaling typically accompanies exertion. Learning to match breath to movement transforms the experience of Pilates from exercise to something closer to meditation in motion.
Flow
The exercises of the Pilates method are not performed in isolation: they flow into one another through smooth, efficient transitions. Flow is the integration of all five preceding principles: when concentration, control, centering, precision, and breath are working together, movement becomes fluid. Flow is the quality that distinguishes a practitioner who has truly absorbed the method from one who is merely executing exercises.
How to use the principles in your practice
Don't try to consciously apply all six principles simultaneously in your early practice: that way lies paralysis. Instead, treat them as a hierarchy to work through over time.
In your first few months, focus on centering and breath. These are the prerequisites for everything else. Once you can reliably find and maintain your powerhouse, and coordinate breath with movement, concentration and control will begin to emerge naturally.
Precision and flow are the last to arrive, and when they do, the experience of Pilates changes completely. You'll stop counting repetitions and start inhabiting them. That's when the practice becomes genuinely transformative.
