What Happened to Yoga in America? How Hot Yoga, Fitness Culture, and Rushed Teacher Trainings Changed the Practice

Exploring the Dichotomy of Yoga: From Mindful Intention to Intense Workout; Reconnecting with the True Essence of the Practice.

There is a question I keep coming back to. When did yoga in America become less about yoga and more about sweating?

Somewhere along the way, many yoga studios began to feel less like places of practice and more like workout rooms. The music got louder. The rooms got hotter. The transitions got faster. The sequencing became more complicated. Classes became crowded, humid, intense, and performance-driven. In many places, the intention behind the postures started to disappear.

I want to be clear. I love movement. I love a strong class. I love a good Buti class. I love practicing with music at times. There is nothing wrong with enjoying strength, rhythm, sweat, or energy in a group class.

That is not the whole of yoga. When every class becomes loud, hot, fast, and physically demanding, we have to ask ourselves an honest question: Are we still teaching yoga, or are we teaching fitness with Sanskrit words sprinkled in?

Yoga Is Not Just the Pose

A yoga teacher should not simply list posture names while students rush from one shape to the next. A yoga teacher should be teaching. That means teaching the how and the why:

• Why are we practicing this pose?

• What is the purpose?

• What is the student meant to notice?

• What should they feel?

• What should they avoid?

• How does this posture affect the spine, the breath, the nervous system, the joints, and the mind?

• How should this student, in this body, practice this pose today?

  
  

The pose is a template. The student is not. Every body is so very different. Every spine, shoulder, knee, hip, nervous system, and lived experience is different. A skilled teacher knows that yoga is not about forcing every body into the same shape. It is about helping each student develop awareness, presence, discipline, and discernment.

That requires training. It requires mentorship. It requires years of learning. It requires humility. It cannot be rushed.

The Problem With “More”

In a dimly lit room, determined individuals push their limits under a neon sign urging "More, Faster, Harder," embodying the relentless drive of modern fitness culture.

In many modern classes, there seems to be a constant push toward more. More heat, more humidity, more complicated sequencing, more transitions, more sweat, more intensity, more noise, and more advanced-looking poses.

More is not always better. Sometimes more is just distraction.

A complicated sequence does not automatically make a class intelligent. A room full of sweat does not automatically mean transformation happened. A playlist that keeps everyone entertained does not necessarily help students become present.

Yoga asks us to pay attention. It asks us to breathe, observe, stay, notice the mind’s reactions, study the body honestly, and practice without needing constant stimulation.

That is very difficult to do when the music is blasting, the teacher is rushing through cues, the heat is overwhelming, and the class is designed mostly to make students feel like they “got a workout.”

Again, there is nothing wrong with a workout. But yoga is not supposed to be reduced to one.

Why Is Everything Hot Now?

Pushing beyond heat limits in pursuit of a "winning" the title of best yogi: the misconception of excessive effort in yoga.

I have asked this question many times, and I rarely receive a clear answer. I have asked teachers, studio owners, and students. I have never received a direct answer.

When I trained in Bikram Yoga, we were taught reasons for the heat. We were taught why it was used, how it was introduced in America, and what purpose it served within that specific method. Whether someone agrees or disagrees with Bikram Yoga as a system, the heat was not random. There was a methodology behind it.

I think part of what happened is that people saw how popular Bikram Yoga had become. They saw the 105 degree room, the 40 percent humidity, the full classes, and the devoted students. But instead of studying the method, the structure, the pacing, and the reasoning behind the heat, many people simply borrowed the heat itself.

They took one visible piece of the practice and added it to completely different styles of yoga, often without the knowledge, training, or wisdom needed to support that choice. Heat became a trend. It became a selling point. It became something studios could advertise. But heat without purpose is not methodology. It is just temperature.

Equally important, in a traditional Bikram-style class, students are not moving continuously like they would in a flow, Pilates, sculpt, or cardio-based class. The class is structured. Postures are held. There are moments of stillness. There is repetition. There is rest built into the format. That is very different from moving continuously for 60 minutes in high heat and high humidity.

I also come to this conversation with a very specific background. I grew up on military bases, and later I served in the Air Force myself. I lived and worked in places where heat was not theoretical. It was dangerous. Texas, Arizona, and Afghanistan all taught me that heat exposure has to be taken seriously.

In the Air Force, we did not just guess when it was safe to train or work in the heat. We followed charts (which you will see below). We followed directives of work and rest cycles in the heat. We paid attention to heat categories, hydration, acclimatization, and risk. Those rules were not suggestions. They were direct orders and they existed because heat illness is real.

That is one reason I struggle with what I see in some heated yoga classes today. In the military, we had strict guidance about how long we could work in extreme heat, how hard we could work, and when we needed rest. But in yoga studios, we sometimes pack people into rooms over 100 degrees, add high humidity, turn up loud music, and keep them moving continuously for an hour. I do not understand why we treat that as normal.

Government and occupational safety agencies take heat exposure seriously. As I discussed previously, The Department of the Air Force’s thermal stress instruction includes guidance around environmental monitoring, acclimatization, work and rest cycles, fluid replacement, and risk management for physical training in heat. It specifically states that physical training leaders must consider the activity planned, work and rest cycles, and available water before training, and that high-intensity activities can create heat illness risk even in lower heat categories.

You can read that Air Force guidance here:https://static.e-publishing.af.mil/production/1/af_sg/publication/dafi48-151/dafi48-151.pdf

The primary Air Force instruction governing heat stress is DAFI 48-151 (Thermal Stress Program), which was issued on May 2, 2022.

Figure 4.1 compares WBGT heat-safety categories for military activity using work/rest cycles and high-intensity sports with continuous exercise, showing that intense activity reaches caution and suspension limits at lower temperatures.

The CDC/NIOSH heat stress guidance is also very specific and direct. It says continuous work in the heat is not advisable, and that workers need periodic rest breaks so the body can cool down. Its sample work and rest schedule shows that at 100 degrees Fahrenheit, even light work includes significant rest time, while moderate and heavy work are flagged with caution.

You can read the CDC/NIOSH guidance here:https://www.cdc.gov/niosh/docs/mining/UserFiles/works/pdfs/2017-127.pdf

This NIOSH work/rest schedule shows how long workers should work and rest based on temperature and workload intensity, helping reduce the risk of heat illness during hot conditions.

This guide explains how to adjust work/rest schedules for sunlight, cloud cover, humidity, and work intensity, and gives a case study showing why rest breaks, hydration, and monitoring are important in extreme heat.

So I keep coming back to the same question. Why have we normalized 60 minutes of continuous movement in rooms that may be 100 degrees or hotter, with high humidity, packed bodies, little rest, and loud music? Why are we acting like this is automatically safe, wise, or yogic?

Heat can have a purpose. Heat should have a purpose. It should not be added simply because students associate sweat with value. And it most definitely should not be added simply because it is trending.

Sweat Is Not the Same as Presence

A student can sweat and still be completely disconnected from their body. They can do an advanced posture and still have no awareness of their breath. It is impossible for them to leave the studio exhausted and still not have practiced yoga.

This is where I think modern yoga has lost its way. Many students now believe that if they sweat enough, they had a good class. Studios know this. Teachers know this. The industry knows this.

Sweat is easy to sell. Stillness is not. Breath is not. Discipline is not. Subtlety is not.

Yoga has never been only about what is easy to market. In yoga, we are meant to build internal awareness. We are meant to learn how to create heat through breath, attention, bandhas, focus, and conscious effort. External heat can support certain practices, especially for beginners who may not yet understand how to cultivate internal heat. But external heat is not a replacement for inner work.

If the only way a class feels powerful is because the room is hot, we should question what we are actually teaching.

Did COVID Change Teacher Training?

Struggling to balance yoga teacher training during COVID, distractions like social media and movies take center stage as true learning takes a backseat.

I also wonder how much changed during and after COVID. During that time, many trainings moved online. Some were thoughtful, rigorous, and well-mentored. Others became self-paced, quick, inexpensive, and disconnected from the kind of direct teacher-student relationship that yoga training has traditionally required.

Online learning itself is not the enemy. There are excellent online educators. There are thoughtful hybrid programs. Accessibility matters. But yoga teacher training cannot become only content consumption.

Watching videos is not the same as being mentored. Memorizing sequences is not the same as learning to see bodies. Passing quizzes is not the same as learning to teach. Completing 200 hours is not the same as becoming ready to hold space for a room full of students with different injuries, abilities, histories, fears, egos, and needs.

Even when a training technically meets the required hours, the deeper question remains: What kind of mentorship is actually happening?

A teacher training should not end when the certificate is handed out. A true yoga teacher stays connected. A true yoga mentor continues to guide. A true yoga trainer understands that graduating students is not the same as completing the responsibility.

I was lucky. My teacher, Emily, has continued to be there for me whenever I have needed guidance. She did not treat mentorship as an extra fee or an inconvenience. She took the role seriously. She understood that yoga teaching is a lifelong learning process.

That is what this path requires.

Commercialism and the Dilution of Yoga

A new yoga student stands overwhelmed in front of a wall cluttered with flashy advertisements promoting various yoga-related offers and teacher training courses, reflecting the commercialized aspects of modern yoga culture.

The modern yoga industry has become exactly that. An industry. And industry often rewards what is fast, scalable, trendy, and profitable.

Pack the room. Turn up the heat. Turn up the music. Offer a quick certification. Create more teachers. Sell more trainings. Add more class formats. Make it marketable. Make it sweaty. Make it look good on social media.

YOGA DOES NOT WORK WELL WHEN WE CUT CORNERS. You cannot shortcut depth. You cannot mass-produce wisdom. You cannot replace mentorship with branding.

You cannot turn yoga into a contest of who can make the hardest sequence, hold the hottest class, or create the most dramatic playlist.

At some point, the practice becomes diluted. Not because every modern class is wrong, and not because every teacher is careless. There are many sincere teachers doing beautiful work. But the roots have to be nourished. If they are not, the practice becomes thinner and thinner until we are left with something that looks like yoga but does not feel like yoga.

Yoga is not only asana. And even asana should be taught with intelligence, purpose, breath, and presence.

What Would It Look Like to Return to Yoga?

Bridging Two Worlds: A shift from the vibrant yet superficial yoga scene to a serene practice anchored in traditional roots and mindful intention.

Maybe the answer is not to reject modern yoga completely. Maybe the answer is discernment. A healthy yoga community can include music and silence. It can include heated classes and non-heated classes. It can include strength, softness, flow, stillness, tradition, creativity, sweat, and quiet.

But right now, in many places, the balance feels off. It is becoming rare to find a class where the room is quiet enough to hear your own breath. It is rare to find a class where the teacher explains the intention behind the pose; where a class is not trying to entertain, exhaust, or impress. It is becoming rare to find a studio that offers yoga as practice, not just yoga as product.

So how do we fix it? We start by expecting more from teacher trainings. We mentor teachers after graduation. We stop pretending that a rushed certification is enough. We teach anatomy, philosophy, breath, ethics, observation, modifications, and the art of actually seeing students.

We stop using heat as a marketing tool without understanding heat stress. We offer quiet classes again. We teach students that sweating is not the same as practicing. We remind teachers that their job is not to perform a sequence. Their job is to guide human beings. We remember that the journey never ends.

There may be seasons when your practice is deeply physical. There may be seasons when your practice is more philosophical. There may be seasons when the work is breath, rest, study, discipline, or simply learning how to be honest with yourself. That is yoga too.

Yoga is not supposed to be an overcrowded room at 108 degrees with 70% humidity, blaring music, speedy transitions, and no explanation of why anyone is doing what they are doing.

Yoga should help us become more present, not more distracted. It should teach us how to listen, not just how to perform. It should give students tools for their bodies, minds, breath, and lives.

Maybe the industry bubble will eventually burst. Maybe the oversaturation of teachers and studios will correct itself. Maybe the people who came only for quick money will leave when they realize this path requires more than a certificate and a playlist.

I hope so. Because yoga deserves better. And so do our students.
