Bikram Yoga vs Hot Yoga: What’s Actually Different

Bikram yoga is a specific, trademarked method: a fixed sequence of 26 postures and 2 breathing exercises, taught through scripted dialogue, in a room heated to 40°C with around 40% humidity. “Hot yoga” is the broader category Bikram sits inside, covering any yoga practiced in a heated room, including heated Vinyasa, hot Pilates, and dozens of studio-specific formats that never follow Bikram’s exact sequence or heat target.

What Bikram Yoga Actually Is

Bikram Choudhury developed the 26&2 sequence in Calcutta, India in the 1970s, drawing on traditional Hatha postures and structuring them into a fixed order designed to work every major muscle group, joint, and organ system in a single 90-minute session. The class is always the same 26 postures and 2 breathing exercises, always in the same order, always delivered through spoken dialogue rather than physical demonstration or music. A 2015 Ninth Circuit ruling found that the sequence itself is not protected by copyright, though the specific verbal dialogue used to teach it can be, which is part of why the format has spread widely under different studio names while staying recognisably the same practice.

What makes Bikram distinct from most other yoga formats is the specificity. There is no improvisation in the sequence, no music, no lighting changes, and no variation from teacher to teacher beyond delivery style. A Bikram class in Bali and a Bikram class in Los Angeles follow the same 26 postures in the same order, which is not true of most other yoga styles. For a full breakdown of exactly how hot that room gets and why, see our guide on how hot Bikram yoga actually is.

What “Hot Yoga” Means as a Category

“Hot yoga” is not a method, it is a description. Any yoga class taught in a heated room qualifies, regardless of the postures used, how long the class runs, or how hot the room actually gets. This includes heated Vinyasa flows, where the sequence changes class to class and temperatures typically run cooler than Bikram’s fixed 40°C target, hot Pilates, which is not yoga at all but is frequently marketed alongside it, and various studio-branded formats that borrow individual postures from Bikram without the full sequence or dialogue.

This is why two people can both say they do “hot yoga” and be describing genuinely different experiences: different postures, different temperatures, different class lengths, and different levels of structure. Bikram is one specific, well-defined format inside that much larger and looser category.

Why the Terms Get Confused: A Brief History

For much of the 1990s and 2000s, “Bikram yoga” and “hot yoga” were used almost interchangeably, since Bikram’s studios were the dominant heated yoga format available. That started to change as independent studios began offering the same 26-posture sequence under different names, often to distance themselves from Bikram Choudhury personally following well-documented controversies, while newer heated formats like hot Vinyasa and hot Pilates grew as separate, less structured alternatives.

The result is a landscape where “hot yoga” now covers everything from a faithful, unaltered 26&2 practice to a 45-minute heated flow with no fixed sequence at all. Bikram YogaFX teaches the original 26&2 sequence and refers to it as the Original Hot 26&2 Yoga, independently of any official Bikram Choudhury teacher training programme, to be clear about what is actually being taught without relying on a name that has become ambiguous.

The Difference Most Comparisons Miss: Heat Source

Almost every article comparing Bikram to hot yoga focuses on sequence and studio branding, and almost none of them mention how the heat itself is produced, because outside of a handful of tropical locations, there is only one option: electric panel heaters or infrared systems. These raise room temperature to 40°C but produce dry heat, typically 20 to 30% relative humidity, since heating air without adding moisture lowers humidity as temperature rises.

At Bikram YogaFX Bali, both the Seminyak and Canggu studios use zero electric heaters. The heat is Bali’s own tropical climate, which produces the humid conditions the method was originally designed around in Calcutta, rather than an approximation of them. This is a genuine, measurable difference from almost every other hot yoga or Bikram studio outside Southeast and South Asia, and it changes how the practice actually feels, not just what it is called. For the full physiological breakdown of why this matters, see our guide on practicing without electric heaters.

What the Research Actually Measured

Most of the clinical research on hot yoga was specifically conducted on Bikram’s 26&2 sequence, not the broader category, since its fixed structure makes it far easier to study consistently across participants. A systematic review by Willmott et al. (2025), covering 43 studies and more than 900 participants, found consistent improvements in flexibility, bone density, and general wellbeing tied specifically to the Bikram format. Tracy and Hart (2013) measured a 20% increase in posterior chain strength alongside flexibility gains after eight weeks of Bikram practice, and a University of Wisconsin study found average heart rates reaching roughly 80% of maximum through a 90-minute class, a sustained cardiovascular load rarely tested in less structured heated flow formats.

This matters for anyone comparing the two on health grounds: claims about “hot yoga benefits” circulating online are frequently based on Bikram-specific studies, then applied loosely to any heated class, including formats that share little with the original sequence beyond the temperature. A heated Vinyasa class at 33°C for 45 minutes is not the same physiological stimulus as a Bikram class at 40°C for 90 minutes, even though both are commonly labelled hot yoga.

Which One Should You Choose?

If you want a structured, predictable practice with a fixed sequence you can track progress against over months, Bikram is the more deliberate choice. Knowing exactly which 26 postures are coming, in exactly what order, every single class, is either the biggest draw or the biggest drawback depending on what you are looking for. Practitioners who prefer variety and a different flow every session generally gravitate toward heated Vinyasa or hot Pilates instead.

A recurring question on yoga forums is whether Bikram is “too rigid” compared to more flexible hot yoga formats. The honest answer is that the rigidity is the point, not a limitation. The fixed sequence exists so the same 26 postures can be studied, taught, and progressed against consistently, which is precisely what allows the research above to exist in the first place. Anyone who finds a changing sequence more motivating will likely prefer a Vinyasa-style hot class, and that is a legitimate preference rather than a wrong one.

For anyone weighing the temperature itself as a deciding factor, our full breakdown of hot yoga benefits covers what the heat specifically contributes beyond the postures, and how that compares across formats. Anyone with a heart condition or other health concern should also read our guide on who should be cautious with Bikram yoga before choosing either format.

The YogaFX Approach: Original Hot 26&2 in Natural Heat

Mr. Ian Terry, E-RYT 500 and founder of YogaFX, trained directly under Bikram Choudhury across 5 events between 2012 and 2019 and has since taught more than 12,000 hours in the room himself. YogaFX is an independent training and studio operation, not an official Bikram Choudhury Teacher Training programme, and teaches the original 26&2 sequence at both the Seminyak and Canggu studios in Bali’s natural tropical heat rather than an electrically heated room.

For practitioners who have only experienced Bikram or hot yoga in an electrically heated studio, practicing the same sequence in Bali’s natural humidity is frequently described as a different experience entirely, not because the postures changed, but because the environment finally matches what the method was designed for. Classes run daily from 06:00 to 22:00 at both locations, and first-time visitors can try a class with a free 1-day guest pass.

FAQ

Are Bikram yoga and hot yoga the same thing?

Not exactly. Bikram yoga is a specific, fixed sequence of 26 postures and 2 breathing exercises taught in a 40°C room. Hot yoga is the broader category that includes Bikram along with heated Vinyasa, hot Pilates, and other formats that vary in postures, temperature, and structure.

Is Bikram yoga always hotter than other hot yoga classes?

Usually, yes. Bikram maintains a fixed 40°C target, while many heated Vinyasa and hot Pilates classes run cooler, often between 32°C and 38°C, since they are not bound to a specific historical temperature the way Bikram is.

Why do some studios avoid calling their classes “Bikram”?

Many independent studios teaching the 26&2 sequence use names other than Bikram, often to distance the practice from Bikram Choudhury personally following past controversies, while still teaching the same sequence he developed. The postures and structure typically remain unchanged even when the name does not include “Bikram.”

Does hot yoga research apply to all heated formats equally?

No. Most peer-reviewed research on hot yoga benefits was conducted specifically on Bikram’s fixed sequence and 40°C target, because its consistency makes it easier to study. Applying those findings to a shorter or cooler heated Vinyasa class is not fully accurate, since the physiological stimulus differs.

Is one format better for beginners than the other?

Neither is objectively better for beginners. Bikram’s fixed sequence means you know exactly what to expect every class, which some beginners find reassuring, while others prefer the variety and typically lower temperature of a heated Vinyasa class as an easier entry point into heated practice.
