THE LAB
TWO FLOORS. TWO DISCIPLINES.
ONE PURPOSE: PROGRESS.
Upstairs, our athletic Reformer sessions happen in small-group classes or personal 1:1 sessions — all powered by next-gen Reform RX machines. Switch between pure coaching or tech-enhanced self-train formats with live tracking, tailored cues, and personalised programming.
Downstairs, our Strength training focuses on smart progressions in an intimate, small-group setting. Minimal gear, maximum intent, and coaching that actually fixes movement patterns instead of hiding them in a crowd.
And we’re just getting started.
The Lab is evolving into fully personalised support — combining 1:1 training, structured progress tracking, and nutrition coaching for clients who want true, long-term change.
You train hard — we handle the rest.
Everything here is designed to keep you focused on output, not logistics.

AMENITIES
OUR
MACHINES
REINVENTING THE WORLD OF REFORMER PILATES. DIGITALLY CONNECTED.
Our Reformers are powered by the most advanced connected training tech in the industry — the first of their kind in Switzerland.
Reform RX fuses precision engineering with built-in tracking, giving you live performance metrics like heart rate, intensity, power output, and calories burned on a 21.5” HD touchscreen.
Each machine supports both fully instructor-led sessions and tech-enabled self-training — so your progress never stops.
The Smart Spine hides the springs for safety and houses next-generation tracking technology, while features like the Infinity Footbar (28 positions, glide mode) and ergonomic handles add unmatched versatility.
This is data-backed, coach-driven training — built for measurable progress, only at the lab.

BEHIND PROTAGONIST
We built PROTAGONIST because most studios weren’t built for people like us.
Too soft. Too aesthetic. Too crowded. Too unfocused.
We wanted something raw, efficient, and performance-led — a place where small-group training actually means coaching, not choreography.
Sara left a career in global corporates and top-tier consulting to create a training space that finally matched her standards. A space that combines athletic Reformer Pilates, progressive Strength Training, private 1:1 coaching and personal training & nutrition guidance for real body recomposition.
Smart machines. Tough coaching. No fluff. Just outcomes.
At PROTAGONIST, progress isn’t a vibe — it’s visible.
Our Reform RX machines track every rep and heartbeat in real time. Our coaches correct form, push precision, and tailor effort — whether you train in a small group or in a personal 1:1 session.
Every detail, from equipment to programming, is engineered to raise the standard of what Reformer Pilates and Strength training in Zurich should be: measurable, intentional, and seriously effective.
No matter your starting point, you’ll find the tools, the data, and the coaching to push further, faster, and smarter.
We’re not a vibe. We’re a standard. And you’re here to raise it.
