THE LAB
TWO FLOORS. TWO DISCIPLINES.
ONE PURPOSE: PROGRESS.
Upstairs, next-gen Reformers bring precision training and the option to switch between pure coaching or tech-enhanced sessions with live tracking.
Downstairs, functional strength work strips it back to the essentials — minimal gear, maximum intent.
The Lab is built for one thing: better output. No noise, no clutter — just a space that gets out of your way so you can get after it. Every detail is engineered to sharpen focus, capture data, and turn effort into progress you can see.
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.
Every machine can run fully instructor-led sessions or switch to hybrid mode — on-screen programming with live coach corrections — so training 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 us — or for people like us.
Too soft, too aesthetic, too unfocused. We wanted something raw. Efficient. Performance-led.
Sara left a career in global corporates and top-tier consulting firms to create a space that matched her standards — and her training style. One that combines smart machines, tough coaching, and no-fluff design. A space that’s stripped-back, seriously effective, and unapologetically focused on progress.
At Protagonist, progress isn’t a feeling — it’s proof you can see. Our Reform RX machines track every rep, watt, and heartbeat, while our coaches push for precision and results. Every decision we make, from equipment to programming, is designed to raise the standard for what a training session should be.
This is a space for people who train with purpose. No matter where you’re starting, you’ll find the tools, data, and coaching to push further — alongside a community that’s doing the same.
We’re not here to sell you a lifestyle.
We’re here to raise the standard — and you raise the bar.
