Pilates Boom: Why Quality May Be Suffering as Popularity Soars

Pilates has exploded in popularity, fueled by social media influencers and celebrities singing its praises. But there's a growing concern that the rapid rise is diluting the quality of instruction. Hailey Bieber, a prominent figure who has embraced the practice, recently remarked that Pilates might be turning into a fad, warning that truly skilled instructors are becoming scarce. This echoes the sentiments of long-time practitioners who are noticing a shift in how Pilates is perceived and practiced.

The Pilates Phenomenon

What exactly is going on in the world of Pilates? In 2025, Pilates became the top-booked workout globally on ClassPass, with bookings surging by 66% from the previous year. It's now part of a combined $19.2 billion market with yoga in the U.S. The growing demand has attracted a wave of investors eager to capitalize on this trend. Studios have popped up nationwide, promising the benefits of Pilates to an ever-expanding clientele.

However, this rapid growth comes with a catch. Many instructors now entering the field lack the extensive training that characterized the practice's origins. Some certification programs offer as little as 40 to 60 hours of mat Pilates training. But to gain a true understanding of Pilates' intricate biomechanics, many experts suggest that a 450-hour program, like that of the National Pilates Certification Program, is essential.

What It Means for Pilates Enthusiasts

But here's the thing, the current space poses challenges for both seasoned instructors and newcomers. Heather Andersen, founder of New York Pilates, has noticed a troubling trend. Many new classes branded as Pilates prioritize speed and intensity over technique and form. This deviation raises questions: Is the integrity of Pilates compromised in the race to meet demand? Are students getting the full benefits of what the practice can offer?

There's a clear divide between traditional Pilates and what some studios market as "Pilates-inspired fitness." Without a governing body to oversee standards, it's easy for practices to veer off course, leading to potential misuse of the term "Pilates." Instructors like Andersen and others who've invested years in training worry that the essence of Pilates, a mindful practice grounded in six core principles, might be lost. And when quality slips, it's the students who lose out.

Takeaway: Mindfulness Over Hype

So what should true Pilates enthusiasts do amid this craze? The key lies in choosing quality over hype. Find instructors with substantial training, ideally over 400 hours, who focus on anatomy and alignment. If an instructor's main focus is on how fast you can move rather than how well, it might be time to look elsewhere.

The real power of Pilates shouldn't be in its trendiness but in its ability to connect mind and body, teaching us how to move efficiently and with purpose. If the practice evolves to meet the demands of the market without losing its roots in mindfulness and precision, it can continue to benefit many. So the next time you step into a Pilates studio, ask yourself: are you investing in a workout that's trending or one that's truly transformative?
