And What Hasn’t



How Fitness Has Changed—And What Hasn’t

From Star-Struck Barre Baby to Self-Paced Training Pioneer

In 1999, I was fresh out of college, living in New York, and chasing a lifelong dream of dancing on Broadway. Fitness was not the plan. Performing was. But like many performers in the city, I was juggling auditions and trying to pay rent. One day, flipping through The Village Voice, I saw an ad for a fitness instructor. I called. Fred DeVito called me back.

That phone call would end up shaping the rest of my life.

I showed up to the Lotte Berk Method studio for the first time a few days later. As I waited for class to start, Julia Roberts walked out of the studio, glowing. I’m just this girl from Maine, and now here I am—watching actual Julia Roberts stroll past me post-workout. Yes, she really is that gorgeous in person.

I hadn’t even taken the class yet, and I was already starstruck. But what happened inside that studio hit me even harder: it felt like something clicked.

Fred had me take class and then tested my flexibility. He told me I’d need to take class every day and start working at the front desk. I said yes. I showed up. Every single day.

Once I was ready to train, my schedule ramped up. I took two classes a day and observed one. There was no manual. No slides. No structured curriculum. Just a notebook. I scribbled down everything I saw and heard. I learned by watching, moving, mimicking. Years later, I’d learn there’s actually a term for that: see and steal. And honestly? It worked.



Barre Then vs. Now

Back then, barre was still this mysterious boutique thing. A small, intense, insider fitness world. It wasn’t on every corner or in every app. It certainly wasn’t trending on Instagram. It was exclusive, it was gritty, it was real.

The Lotte Berk Method was unlike anything else. It wasn’t yoga, it wasn’t dance class, it wasn’t strength training—but somehow it was all of those things. It was hard. It was precise. And it worked.

When I moved back to Maine and opened my own studio, I wanted to train teachers to carry that same spark I’d felt in NYC. But I also wanted to improve the training process. I remembered my Pilates certification with STOTT back in 2001—organized, manual-based, filled with lectures and peer practice. That structure was calling me. So I merged the two ideas: the intensity of barre, with the thoughtful education of a Pilates certification.

In 2006, I launched my first teacher training. It was 5 full days—8 hours a day. It was, in a word: brutal. My trainees were exhausted, overwhelmed, exhilarated, and transformed. My dad used to say people “looked like they’d been shot at and missed, shit at and hit.” That pretty much described my poor students by day five.

Eventually, I realized I needed to break it up into three levels. It was just too much to absorb all at once.



A Changing Industry

It’s been almost 20 years since then, and the fitness world has completely changed.

Now, most people have heard of barre. A lot of people have taken barre classes. You don’t need to explain what tuck, pulse, or under-the-barre means anymore. Group classes are the norm, boutique fitness studios are everywhere, and people expect more from their instructors than ever before.

There are more paths to becoming a teacher now, and more ways to deliver education. And for me, that meant it was finally time to revisit the structure of my own training programs—again.

With so much content available online, and more people than ever entering fitness through hybrid or second-career paths, I wanted to meet them where they were. Not just in the studio, but in their life.



Back to the Basics—With a Modern Twist

So now, I’ve come full circle. I’ve condensed both my Barre and Mat Pilates trainings into one accessible course each. Not a watered-down version—these are the full certifications. But what’s different is how you access them, and how you use them.

They’re self-paced. They’re digital. And they’re personalized.

Just like when I first started, the heart of the program is still the same: you learn by doing. But this time, you also have a manual. You have lectures. You have class plans. You have coaching—if you want it. You get to choose how deep you go.

It’s mentorship-ready. That means if you already work with a Pilates teacher, studio owner, or movement mentor, they can guide your practice alongside the course. Or, you can work directly with me. Or… you can just do it on your own. It’s your call.



Who It’s For (and Who It Isn’t)

These trainings aren’t just for people who want to teach full classes.

If you’re a Physical Therapist or Occupational Therapist who wants to integrate safe, intelligent movement into your clinical work—this is for you. You may never want to lead a group class, and that’s okay. You’ll walk away with skills you can use one-on-one with patients and clients.

If you’re a studio owner and you’re tired of waiting for the next in-person certification to train your staff—this is for you. You can use the self-paced course to cross-train employees when you have time, not when the schedule tells you to.

If you’re a lifelong student of movement who just wants to know more—this is for you. Learn at your pace, in your space.

But here’s who it’s not for: someone who’s expecting to be spoon-fed. The course will guide you, but it’s also going to ask something of you. You’ll need to show up, observe, practice, apply, and engage.

Just like I did at Lotte Berk. Just like all of us did, before YouTube tutorials and Instagram workouts.



Why It Matters

Fitness has changed, yes. But the body hasn’t.

The way we learn has evolved, but the need for smart, thoughtful, effective movement hasn’t. People still need strength, flexibility, balance, control, and confidence. They still need to recover from injuries, to feel empowered in their bodies, to understand how they move—and why it matters.

I love that we now have the tools to make movement education more accessible. I love that I can offer a full certification to someone in a small town in Montana or India or Maine. I love that we can meet students and teachers exactly where they are—and still ask them to rise to something more.

Fitness may have started out as a side hustle for me. But it has become my life’s work. And now, I get to share that with the next generation of teachers, therapists, and passionate movers.

Whether you're stepping into the studio, or hitting play from your living room—welcome. I can’t wait to see what you’ll build from here.

There is a common misunderstanding about Pilates that has grown louder over the years: that it is meant to be gentle, slow, soft and easy. A “nice” workout. But that was never the intention. Pilates was not created to be performative. It was created to be effective. Effectiveness in movement does not come from looking impressive. It comes from precision. Somewhere along the way, the visual of Pilates became louder than the method itself. Long limbs moving with beautiful choreography and endless repetitions. Classes that look like Pilates. But looking like Pilates, being called Pilates and being Pilates are not the same thing. And most people, including many teachers, skip the part that actually makes it work. Pilates Was Never Meant to Be Performative Joseph Pilates did not design a system that rewarded momentum. He designed a system that required attention. Not attention to how something looks, though that is how you can tell if the exercises is executed properly. The attention should ideally be to how something is done. Modern fitness culture thrives on performance. Movement is filmed, shared, and packaged visually. The more dynamic it looks, the more engaging it appears. The more repetitions, the more it seems productive. This is where Barre and Pilates differ. This is where those lines have blurred and I quietly hope Pilates can resists this fad. A well-taught Pilates class may look almost uneventful from the outside. To someone expecting entertainment, it can seem understated. To the nervous system, it is deeply demanding. Because Pilates was never designed to entertain the eye. It was designed to reorganize the body. It is art, but not for arts sake. Precision Requires Attention Precision creates actual change. When movement becomes rushed, the body defaults to habit. Stronger muscles take over. Momentum replaces control. Alignment becomes approximate instead of intentional. Slowing down in Pilates is not about being gentle. It is about being accurate. It allows the brain to register position, and control. It gives the body time to respond instead of react. Precision is not passive. It is neurologically active. Holding a half curl with the neck long, ribs quiet, and breath organized requires far more attention than swinging through ten repetitions with momentum. Performing a leg circle without pelvic movement demands significantly more control than making the circle bigger or faster. The difficulty in Pilates is rarely about load. It is about coordination. Coordination should not be rushed for the sake of getting in more repetitions. Many Classes Look Like Pilates, But Aren’t Being Taught to Bodies This is where the disconnect becomes most visible. Exercises are demonstrated, copied and followed. Social media has taken the see and steal culture to new lengths! This leads to the body in front of the teacher is not being taught properly. Clients are becoming carbon copies of braod movements seen online and just simply being asked to replicate. There is a difference between cueing choreography and teaching movement. When classes focus primarily on what the exercise should look like, participants often compensate without realizing it. The neck grips during abdominal work. The hip flexors dominate leg movements. The lower back absorbs what the abdominals were meant to support. From the outside, everything appears correct. From the inside, the wrong muscles are doing the work. I know this to be true, because I have definitely performed Pilates.. and on an off day... I am sure I will unfortunately do this again. This has allowed me to really see though, that Pilates teaching requires observation. It requires adjusting range of motion, tempo, setup, and intention based on the individual body, not the idealized version of the exercise. Because the goal of Pilates is not uniform movement. It is intelligent movement. Real Pilates Feels Quieter, and More Demanding Neurologically One of the most surprising experiences for clients transitioning from performative classes to precise Pilates is how “quiet” it feels. There is less rushing and far less choreography for the sake of variety. Yet, thes classes often feels more challenging. Not because it is harder in the traditional fitness sense. But because it requires sustained mental engagement. You cannot mentally check out during precise Pilates. You are asked to notice: Where your ribs are How your pelvis is responding Whether your neck is assisting unnecessarily If your breath is supporting or disrupting the movement Which muscles are initiating versus compensating This level of awareness increases the neurological demand significantly. The brain is actively mapping movement rather than passively repeating it. That is why Pilates can feel deceptively demanding even when the exercises appear small or controlled. It is not about exhaustion. It is about organization. Gentle Is Often a Misinterpretation of Control When Pilates is described as gentle, it is usually because it lacks impact, heavy loading, or aggressive pacing. But low impact does not equal low intensity. Holding alignment under control. Moving without compensation and maintaining precision through fatigue. These are not gentle skills. They are refined skills. In fact, when Pilates is taught with true precision, many clients realize they have been overworking the wrong areas for years. Their hip flexors tire quickly. Their neck becomes aware. Their deep abdominals fatigue in ways they never noticed before. Not because the workout is harsher. But because it is finally specific. Specificity feels different than intensity. Why Precision Gets Skipped Skipping precision is rarely intentional. It is often the result of: Large class sizes Fast-paced programming Overemphasis on choreography Teacher insecurity around slowing things down The pressure to make classes feel “worth it” through visible effort Precision requires time. It requires observation. It requires confidence in subtlety. And subtle teaching can feel risky in a culture that equates visible sweat with value. But when precision is skipped, the method gradually becomes diluted. Exercises become shapes instead of tools. Cueing becomes generalized instead of specific. And the neurological depth of Pilates is replaced with surface-level movement. Teaching Pilates to Bodies, Not to Exercises One of the most important shifts a teacher can make is moving from teaching exercises to teaching bodies. An exercise is not the goal. It is the vehicle. Two people performing the same movement may need entirely different cueing, range, and pacing to achieve the intended outcome. Precision means recognizing that and adjusting in real time. It means allowing fewer repetitions with better execution. It means refining setup before adding progression. It means valuing stillness as much as movement. And perhaps most importantly, it means being willing to make the class feel quieter in order to make it more effective. Because when the body is truly learning, it does not need constant spectacle. It needs clarity. The Quiet Demanding Nature of True Pilates Clients who experience precise Pilates often describe it the same way: “It felt small, but I was working so hard.” “I had to concentrate the whole time.” “It was harder than it looked.” This is not accidental. When the nervous system is fully engaged, even controlled movements require significant effort. The demand shifts from gross muscular output to refined neuromuscular coordination. That is the part most people skip. And it is also the part that creates lasting change. Not bigger movements. Better ones. A Method That Rewards Thoughtfulness Pilates does not reward rushing. It does not reward performance. It does not reward spectacle. It rewards attention. It rewards consistency. It rewards intelligent progression. It rewards teachers who are willing to observe rather than simply lead. And in a fitness landscape that increasingly prioritizes how movement looks on camera, this quiet precision becomes even more valuable. Because bodies do not improve through performance. They improve through accurate, repeated, intentional movement. Reclaiming Precision in Modern Pilates Reclaiming precision does not mean making Pilates rigid or overly clinical. It means returning to its original intelligence. It means: Teaching fewer exercises more effectively Slowing down when needed Cueing for sensation, not just shape Observing compensation patterns Prioritizing neurological engagement over visual intensity When this happens, Pilates stops feeling “gentle” in the dismissive sense and starts feeling deeply effective. Subtle. Focused. Demanding in the way that truly organized movement always is. And that is where the real method lives. Not in performance. Not in speed. Not in how impressive it appears. But in the precision that most people overlook. Pilates doesn’t need to be harder.
