The Six Principles Pilates Never Wrote

Ask any certified instructor what principles govern the method and, in all likelihood, they’ll recite the same list: Concentration, Control, Centering, Flow, Precision, Breathing. Six words, in that order, that show up in the curriculum of nearly every training course in the world, almost always presented as if they came straight from Joseph Pilates’ own mouth — or pen.

They don’t. Or at least not like that.

The only book Pilates devoted entirely to explaining his method in writing is Return to Life Through Contrology, published in 1945 with William John Miller. It has a preliminary chapter of barely twenty pages before moving on to the instructions for the thirty-four floor exercises, and that chapter does, in fact, contain a section literally titled “Guiding Principles of Contrology.” We read it in full, word by word, looking for that list of six. It isn’t there.

What he actually wrote

What’s there instead is a handful of scattered ideas, presented more as convictions than as a pedagogical framework. On mental control of the body, he writes — in capitals in the original, like someone underlining with their voice: “IDEALLY, OUR MUSCLES SHOULD OBEY OUR WILL. REASONABLY, OUR WILL SHOULD NOT BE DOMINATED BY THE REFLEX ACTIONS OF OUR MUSCLES.” On concentration, he asks the reader to keep the mind “wholly concentrated on the purpose of the exercises” while performing them, without straying an instant from the instructions. On patience over shortcuts, he cites the philosopher Schopenhauer — “to neglect one’s body for any other advantage in life is the greatest of follies” — and follows it with a plain reminder: “Rome was not built in a day.”

There’s control, no doubt. There’s something close to concentration. There’s, in the following chapter, devoted almost entirely to breathing, an instruction that repeats like a mantra: “‘SQUEEZE’ EVERY ATOM OF AIR FROM YOUR LUNGS UNTIL THEY ARE ALMOST AS FREE OF AIR AS IS A VACUUM.” The ingredients of several of the six principles are there, scattered through the text. What isn’t there is the list: numbered, closed, with those exact six nouns functioning as the six legs of a table.

Why the difference matters

This isn’t archival pedantry. It’s closer to the kind of nuance that separates a method’s real history from its marketing legend — and that distinction is precisely why this section exists. That a pedagogical framework was built afterward, by second-generation teachers who needed clear, memorable language to teach something Pilates transmitted mostly through physical demonstration, doesn’t take away an ounce of value from those six principles as a teaching tool. Thousands of instructors use them every day with real results. But teaching them as if they were a verbatim quote from 1945 is exactly the kind of legend Movente marks as legend, not fact — the same way we handle the never-confirmed story that no Knockaloe internee died during the 1918 flu.

What the 1945 book does make unmistakably clear, on the other hand, is something rarely quoted, and that may matter more than any list of six words: for Pilates, body, mind, and spirit were not three things a good training regimen had to address separately, but one. He closes the preliminary chapter calling it a “coordinated and balanced tri-part unity of body, mind, and spirit,” and invokes the old Latin motto — mens sana in corpore sano — as a summary of everything before it. If there’s one line from the original worth putting on a studio wall, that’s it. It doesn’t need an invented list of six to sound like a foundation.
