Why Do We Get on the Machine from the Left? Pilates Etiquette That 90% of Instructors Don't Know
In a Pilates studio, the way we get on and off machines and walk around them is often done casually. In reality, there is an "etiquette" here that is packed with Joseph Pilates' philosophy and biomechanical logic.
It is a great waste to dismiss these as "just local rules" or "matters of manners." By breaking down the reasons for each movement and understanding their essence, the clarity of your instruction will improve dramatically.
In this article, we will deconstruct the "three implicit etiquettes" of Pilates machines and explore their profound reasons.
Etiquette 1: Get on the machine from the "left side (non-dominant side)"
Just as there is a strict etiquette in horsemanship to "mount a horse from the left," there is guidance in the world of Classical Pilates to "approach the machine from the left side and sit down from the hips." There is a clear physical reason for this that goes beyond mere appearance.
Strengthening the non-dominant side and correcting imbalances About 90% of the population is right-handed, and we unconsciously start movements using the right side as the axis. By intentionally getting on and off the machine from the "non-dominant side (usually the left)," the goal is to stimulate the nervous system on the side less used in daily life and correct physical imbalances (left-right differences).
The exercise called "transition" Placing your hips on the carriage from the unfamiliar left side and lying down smoothly. This moment of "getting on and off (transition)" is not a break time to let your guard down. The moment of switching movements is actually part of the exercise to train your core control ability to every corner.
Etiquette 2: "Never step over" the machine
"Never step over the equipment"—this is the most famous and absolute rule in Pilates. This is intertwined with the following three important elements.
1. Thorough safety management (complete elimination of risk) Reformers and Cadillacs are composed of moving carriages, rails, and springs with strong tension. If your foot gets caught while trying to step over the machine, it can lead directly to serious injuries such as falls. Because a small moment of carelessness, such as "taking a shortcut and stepping over," can lead to a major accident, it functions as an absolute safety standard to reduce physical risk to zero.
2. Embodiment of "Contrology" (uninterrupted concentration) The original name of the method is "Contrology (control of mind and body)." Instead of unconsciously taking a shortcut and stepping over the machine, you should "walk around" with intention. That in itself becomes training to maintain awareness of your own body and space. It is a mental rule to ensure that the connection between mind and body is not interrupted for even a second during a session.
3. Respect for the equipment (the machine as a partner) Traditional instructors treat the machine not just as a "muscle training tool," but as a "partner" that correctly guides the body's movements. Just as one must not step over sacred dojos or tools in martial arts, the spirit of paying deep respect to the machine that supports you is strongly reflected here.
Etiquette 3: Clarify the "front/back" of the machine
When you say "face the front of the machine" during instruction, can the client face the same direction without hesitation? The definition of the "front and back" of a machine is a "common language of space" within the studio. Defining this is the greatest key to eliminating operational inconsistencies in group classes where multiple people move, or in studios where diverse instructors are present.
Reformer: The "footbar side" is the front. As the names of exercises like "Front Rowing" indicate, the direction facing the footbar is the front.
Chair (Wunda / Combo Chair): The "pedal side" is the front. The state where the client stands or sits facing the pedal is the standard.
Ladder Barrel: The "ladder side" is the front. Since many approaches begin from the ladder side, this is treated as the front.
Cadillac: Because it is bed-shaped, the ambiguous expression "front and back" is a source of accidents. As instructional language, it is essential to define it by physical part names such as "PTB (Push-Through Bar) side" or "RDB (Roll-Down Bar) side" and to clearly distinguish it as "Head end" or "Foot end" according to the client's position.
Summary: Etiquette creates a "special space"
The three etiquettes we deconstructed this time are not techniques of the movement itself. However, by thoroughly implementing them, a pleasant sense of tension is created in the studio, signaling that "this is a special space different from daily life, where you focus 100% on your own body."
"Why does that rule exist?" For an instructor to deeply understand and embody this is the solid foundation for providing high-quality sessions.
Editor's Note
Since there are organizations that [mount from the left], I wondered if Mr. Pilates or the Elders had taught this directly, so I looked into it.
I could not find definitive evidence that this is an absolute rule common to all of Pilates. However, in some studios and schools, this habit may be strictly observed for reasons such as safety, spatial control, left-right body balance, and historical influence (equestrianism). It can be said that this functions as a strategy to build a sophisticated studio brand that goes beyond mere safety measures, or as an instructor's approach to improving the quality of movement.
I also had a question about each machine: [Which way should I face before standing on the left?], so I looked into that as well. Basically, in Pilates, you face all directions according to the movement, so I had never paid attention to front, back, left, or right.
Also, in Japan, there are cases where sessions are held in small spaces and it is unavoidable that you cannot stand on the opposite side!
The theory of mounting from the left is not a strict rule, but I was able to understand the background of how it came to be, so I am personally satisfied.
