You know the feeling if you’ve ever tried to book a reformer class on a Tuesday night. The app shows three spots left, then one, then “class full” before you’ve even decided if you can make it. Boutique fitness has built its whole business model on that scarcity. Someone just decided to build a much bigger room instead.
Here’s what’s actually going into that room, who’s behind it, and why the size alone is worth your attention.
1. What was announced, and when
Sweat and Tonic, a Toronto-based fitness company, announced on October 16, 2026, that its REFORMD studio brand is coming to Southern California, according to Retail Insider’s report on the announcement. It’s the brand’s first U.S. location.
The studio is going into The Commons at Calabasas, a Caruso-developed shopping center, with a January 2027 opening set, per that same report. You can check every figure in this piece against that source yourself.
2. The number everyone’s repeating
You’ll see 37 attached to this story everywhere. That’s how many Lagree EVO PRO machines the Calabasas studio will hold, Retail Insider reports. Thirty-five sit in the main group studio, the one you’d actually book a class in; the other two are in a separate private training space.
If you’ve ever taken a class in a room with ten or fifteen reformers, you already know what a jump that is. Thirty-five in one room changes what a “full class” even means here.
3. Whose claim “largest in the world” actually is
Sweat and Tonic calls the Calabasas location the world’s largest Lagree studio. Retail Insider reports that as the company’s own description, not as something it independently verified against every other Lagree studio you could line it up against.
This isn’t even the first time the company has said it. Its Toronto flagship was billed the same way when it opened in 2025, with 30 machines, according to a Health Club Management report. The superlative is how this company talks about itself. You don’t have to take “world’s largest” at face value to find the growing machine count interesting.
4. What else shares the building
This isn’t only reformers. The plans include six wellness and treatment rooms, Retail Insider reports, offering massage therapy, dry flotation, cryotherapy, compression therapy, and a treatment called the Ammortal Chamber.
There’s also a separate recovery lounge with Therabody equipment and lymphatic massage rollers. If you’ve ever finished a hard class and gone straight to your car because there was nowhere to sit, this building was designed around the opposite instinct.
5. Who’s actually running it
The name attached locally is Heather Perren, a Lagree Senior Master Trainer and Director of Events at Lagree’s own headquarters, per Retail Insider. She grew up in the Calabasas area and will principally own and operate the location — a hometown detail you don’t always get with a company this size.
Lagree Fitness’s own trainer bio page lists Perren as a Senior Master Trainer appointed in 2020, after she started teaching the method in 2015 and built an online following teaching virtual classes from home. That’s longer than most studio owners you’ll meet have spent on a single method.
In her own words: “We’re creating something that goes far beyond a traditional fitness studio,” Perren told Retail Insider, describing a vision to bring “world-class Lagree training, innovative wellness and recovery” together in one place.
6. What Lagree actually is
You’ve probably heard “Lagree” used almost interchangeably with “reformer Pilates,” but it’s a distinct, patented method performed on a proprietary reformer machine — the EVO PRO is the version used here, per Retail Insider’s reporting.
Sebastien Lagree, the method’s inventor, has described it as combining bodybuilding principles with slow, controlled movement. He names five components it’s built around: endurance, cardiovascular fitness, body composition, flexibility and strength, according to a 2025 Health Club Management report on the brand’s debut. That’s his own description of the method, not a claim this site is making about your body.
If you ever see a specific health benefit attached to Lagree elsewhere — a calorie count, a posture promise — ask who’s actually behind it. Trace it to a named study or a credentialed professional before you take it as fact, never to a studio’s own marketing copy.
7. Why size is the actual bet here
Boutique studios usually scale by opening more small locations, not one giant one. A ten-machine room is cheaper to lease and less risky if a neighborhood’s interest cools than you’d think.
Thirty-five machines in one room is a bet that demand here runs deep enough to fill that many spaces, again and again, at a price that also covers six treatment rooms and a lounge. You don’t need a finance background to see the arithmetic: more machines only pencils out if people actually book them. Whether that bet pays off is something you’ll get to watch after January 2027, not something anyone can promise you now.
8. What this means for you
If you’re nowhere near Calabasas, this is a curiosity — a sign of where boutique fitness is willing to put its money next. If you are, it’s a concrete thing to actually watch for.
Either way, this isn’t about whether you need a Lagree class, and it isn’t about the body of anyone who takes one. A 37-machine studio opening in one zip code tells you something about where a company thinks the market is heading. It doesn’t tell you anything about what you should be doing with your Tuesday nights.
You get to decide whether that’s interesting or beside the point. Either answer is yours to make.
