"Reformer Pilates" simultaneously became the #1 fitness query in six European countries in January 2026. Not the fastest growing, but the first. Ahead of running, ahead of HIIT, ahead of yoga. This isn't a rising niche trend. It's a game changer.
If you live in a major European city, you've probably noticed it without even realizing it. New studios have opened. Friends who never exercised started talking about it. Waiting lists appeared where there were none six months earlier. And Instagram started showing you machines you didn't even know how to name yet.
This guide explains why all this is happening now, what is fundamentally different about Reformer Pilates compared to mat Pilates, and most importantly, what concrete changes it brings to the outfit you'll wear to a studio.
Why the Explosion Now
The Reformer is not new. Joseph Pilates invented the machine in the 1920s. It was used for decades in specialized studios, with a clientele of dancers, athletes in rehabilitation, and a few initiates who were in the know. What changed in 2025-2026 is the convergence of three independent phenomena that produced something unexpected.
Studio Accessibility has Changed Category
For a long time, Reformer Pilates was synonymous with private lessons at €80-120 per session, in discreet studios frequented by people who didn't need to budget for it. This model still exists, but it has been joined by a second model: group studios at €35-55 per session, with 4 to 6 machines per room, often in a semi-private format. Reformer Pilates has gone from an inaccessible luxury to a reasonable investment, comparable to a premium gym membership.
At the same time, the proliferation of studios in European capitals has created competition, which has driven prices down and made discovery possible for a much wider range of clients.
TikTok and Instagram Did the Education That Studios Didn't
Explaining the Reformer to someone who has never seen it is difficult. A 30-second video is not. From late 2024, Reformer content on social media exploded, not studio advertisements, but organic content from practitioners filming their sessions, showing the machine, and describing their results. This type of content does what word-of-mouth used to do, but at a fraction of the speed.
The moment a practice goes from "I've heard of it" to "I've seen exactly what it is and I want to try it" is when bookings take off. This threshold was crossed in Europe during 2025.
January Seasonality Acted as a Trigger
January is always the month for fitness resolutions. What's different in 2026 is that for the first time, a significant portion of this resolution traffic didn't head to traditional gyms; they looked for "Reformer Pilates." Post-New Year surveys in several European countries show the same trend: people didn't want to "exercise more"; they wanted to "exercise differently." The Reformer was there, perfectly positioned to meet this expectation.
💡 The figures that confirm the shift
"Reformer Pilates": +1,000% growth in Google searches in France over 24 months. #1 fitness query in January 2026 in France, Spain, the United Kingdom, Germany, the Netherlands, and Sweden simultaneously. Demand for Reformer studios exceeds available supply in all major European cities; waiting lists indicate that demand has not yet stabilized.
What's Different from Mat Pilates
This question comes up often, and it deserves a real answer, not a marketing summary. Reformer and mat Pilates share the same basic philosophy: core work, movement precision, body awareness. But the physical constraints are fundamentally different.
On a mat, you work against the resistance of your own body and gravity. On the Reformer, you work with a system of adjustable springs that can both facilitate and complicate movements depending on the setting, allowing for intensity adaptation with a precision impossible on the mat. The machine also guides alignment: it corrects where mat Pilates leaves more room for compensation.
The concrete result: the Reformer is often more accessible for beginners (the machine compensates for initial muscular weaknesses) and simultaneously more demanding for advanced practitioners (the springs allow for very fine progressions). This is rare in fitness: the same machine that welcomes beginners and doesn't bore experts.
What the Machine Demands of Your Outfit, and What the Mat Doesn't
This is where many practitioners are caught off guard during their first session. The machine has rails, cables, a movable platform. It is not indifferent to what you wear.
Leggings with thick side seams will rub against the machine's rails during exercises with legs in the air or in a side position. Clothing that is too loose can get caught in the cables, not dangerously, but enough to interrupt movement and force you to try again. Low-rise leggings will consistently slide down every time you extend your legs upwards.
And there's another issue that studios never mention but instructors notice immediately: the Reformer requires the instructor to see your alignment. Hips, knees, ankles – they need to be able to observe and correct in real-time. Clothing that is too loose or too thick conceals precisely the information they need to help you.
⚠️ What your instructor might not tell you
Trained Reformer instructors correct alignment by eye. If your outfit hides your knees or the angle of your hips under excess fabric, they work with less information, and you lose some of the educational value of the session. It's not a question of style; it's a question of correction effectiveness.
What to Wear for Reformer Pilates
Here's what really works, not a list of brands, but the concrete characteristics that make a difference on the machine.
Leggings: The 4 Non-Negotiable Criteria
- Fitted, not compressive. Leggings should follow the body without being excessively tight. The fit allows the instructor to see alignments; however, too much compression hinders proprioception, your ability to feel what you are doing. Compression running leggings are not the best choice for the Reformer.
- 360° stretch, without mechanical resistance. In Reformer, movements go in all directions—legs in the air, twisting, lateral extension. Leggings that stretch well horizontally but restrict vertical flexion will literally limit your range of motion. Multidirectional stretch is the most underestimated criterion.
- No zippers, no thick side seams. Any metal or hard plastic part on leggings becomes a point of friction against the rails and platform of the Reformer. Thick side seams create the same problem in side-lying exercises. Seamless leggings eliminate both these issues at once.
- High-waisted, imperatively. Reformer exercises frequently involve placing the legs above the pelvis or the practitioner in an incline. Mid-rise leggings slide down with every sequence, which interrupts the movement, causes discomfort, and distracts attention precisely when it should be focused on alignment.
Tops: Fewer Constraints, But a Few Rules
A sports bra or fitted crop top works best for Reformer, for a simple reason: a top that hangs below the waist will interfere with your movement as soon as you work in extension. It's not dangerous, but it's annoying and distracting. A medium-support sports bra, not the rigid structure of a high-impact sports bra, is ideal: it supports without compressing your rib cage, which you need for proper breathing during exercises.
Socks: Not Optional
Almost all Reformer studios require non-slip socks, often the small silicone-studded socks seen everywhere. This is a matter of hygiene (the platform is shared) and safety (feet will slip on the moving platform without non-slip grips). If you arrive without them, most studios sell them at the reception, but it's best to bring your own.

Frequently Asked Questions about Reformer Pilates
Do you need shoes for Reformer Pilates?
No, Reformer Pilates is practiced barefoot or with non-slip socks. Shoes are never worn, for hygiene reasons (the platform is shared) and practical reasons (the exercises require feeling the resistance under your foot). Non-slip socks with silicone grips are mandatory in most studios, so bring a pair or buy them at reception.
Is Reformer Pilates suitable for beginners?
Yes, and it's often more accessible than mat Pilates for beginners. The machine guides movement and compensates for initial muscular weaknesses. What matters is choosing a studio that offers real introductory sessions with small class sizes (4 to 6 people maximum for beginners). Avoid: group classes of 10 people where the instructor cannot correct you individually during a first session.
How often per week for Reformer Pilates?
2 sessions per week is the minimum to see noticeable progress. The unofficial rule of Pilates says it takes 10 sessions to feel it, 20 for others to see it, and 30 to have a new relationship with your body. This progression spans 4 to 6 months with 2 weekly sessions. 3 sessions accelerate results without causing excessive fatigue.
What to wear for Reformer Pilates if you are a beginner?
Tight-fitting high-waisted leggings, without thick side seams, stretchy in all directions. Avoid zippers, buttons, or any hard elements that could rub against the machine. A crop top or a medium-support sports bra completes the outfit. The goal: for your instructor to see your alignment and for the machine to never feel your clothing. For beginners in particular, visual corrections from the instructor are essential — fitted clothing makes them possible.
