Hot Yoga Name: Bikram, 26 and 2, and Hot 26 Explained

Hot yoga has several official names, and the most well-known is Bikram yoga, a structured 90-minute practice performed in a room heated to 40°C (104°F). The name you see on a studio’s schedule depends on when it was built, who trained its teachers, and whether the owners chose to distance themselves from the practice’s controversial founder.

This matters because millions of people search for hot yoga classes without realizing they are all looking at the same 26-pose sequence under different labels. According to the National Center for Complementary and Integrative Health (NCCIH), yoga is one of the most widely practiced complementary health approaches in the United States, with hot yoga variants growing steadily in participation since the early 2000s.

This article covers every major name for hot yoga, the history behind them, the 26 poses in the sequence, the real science behind the heated room, safety guidelines, and who the practice suits best.

Hot Yoga Name: What This Practice Is Actually Called

The most accurate answer is that hot yoga is the umbrella name, and Bikram yoga (also now called 26 and 2 yoga or hot 26) is the most structured form within that category.

Hot yoga simply means yoga practiced in a heated environment. It does not specify a style, sequence, or temperature. Bikram yoga, by contrast, refers to one very specific system: 26 postures and 2 breathing exercises, practiced in the same order, every single class, in a room set to 40°C and 40% humidity.

The distinction matters when you are choosing a class. A studio advertising “hot yoga” might run a Vinyasa flow at 32°C. A studio advertising “26 and 2” is running the original Bikram sequence, regardless of what name appears on the door.

Pose Tip:

• Hot yoga (umbrella term): any yoga in a heated room, variable temperature and sequence
• Bikram yoga: the original trademarked 26-pose sequence, 90 minutes, 40°C
• 26 and 2 yoga: the current preferred name for the same sequence, post-trademark dispute
• Hot 26: shorthand used by many independent studios for the same sequence

What Is Hot Yoga Called in Different Studios?

What hot yoga is called depends almost entirely on the studio’s history and the credentials of its teachers.

Studios that trained teachers through Bikram Choudhury’s official certification program before 2017 often kept the Bikram name longest. After a series of legal and ethical controversies became widely documented, many studios rebranded independently. They kept the same 26-pose sequence but renamed it 26 and 2, hot 26, Original Hot Yoga, or simply the Sequence.

A 2020 survey by Yoga Alliance found that teacher-led rebranding was among the most common studio responses to the Bikram Choudhury controversy, with studios citing student trust and public perception as primary drivers.

Here is how the names typically break down by context:

Bikram Yoga Definition: The Official Starting Point

Bikram yoga is a standardized hot yoga system consisting of 26 postures and 2 pranayama (breathing) exercises, practiced in a fixed sequence over 90 minutes in a room heated to 40°C (104°F) with 40% humidity.

Every class follows the same order, every time. That predictability is intentional. The sequence was designed so that each pose prepares the body systematically for the next one, building heat, opening specific joints, and flushing the cardiovascular system in a progressive pattern.

The word “Bikram” is a proper name, not a Sanskrit term. It refers to the practice’s founder. This is one reason the name has become contested: the practice itself has no new name of its own and carries its founder’s name in a way that most yoga styles (which are named for their form or lineage) do not.

The International Journal of Yoga published research describing Bikram yoga’s format as unique among hot yoga styles because of its non-negotiable sequence structure, distinguishing it clearly from heated Vinyasa or heated Hatha classes where sequences vary by instructor.

Key Takeaway: Hot yoga is the general category. Bikram yoga, 26 and 2, and hot 26 are all names for the same specific 26-pose sequence practiced in a room at 40°C. The name on the studio’s schedule tells you something about that studio’s history, not a different workout.

History of Bikram Yoga: Where This Practice Began

The history of Bikram yoga begins in Calcutta, India in the 1940s and 1950s, and it runs directly through one man’s personal training, ambition, and eventual controversy.

The 26-pose sequence has roots in classical Hatha yoga, specifically the teachings of Bishnu Ghosh, a celebrated Indian physical culture teacher and younger brother of the famous yogi Paramahansa Yogananda. Ghosh ran a famous school in Calcutta that emphasized therapeutic yoga and physical rehabilitation. The sequence that became Bikram yoga was drawn from this tradition.

The format was codified and heated rooms were introduced when its developer brought the practice to Japan in the 1970s, then to the United States. By the 1980s, studios were appearing in major American cities. By the 1990s, Bikram yoga had become one of the most commercially successful yoga brands in the world, with a global network of affiliated studios.

The practice reached its commercial peak in the early 2000s. At that point, more than 1,700 affiliated studios operated worldwide, according to estimates cited in journalism covering the Bikram brand during that period. The heated room, the fixed sequence, and the 90-minute structure were all consistent across every location, making it one of the most standardized yoga systems ever built.

Who Created Bikram Yoga?

Bikram Choudhury created and trademarked the Bikram yoga system, beginning his teaching career in India and expanding it globally through the United States starting in the early 1970s.

Choudhury was born in Calcutta in 1944 and trained under Bishnu Ghosh from a young age. He has claimed to have been an Indian national yoga champion, though those claims have been disputed. What is verifiable is that he trained under a legitimate physical culture and yoga lineage, adapted the sequence, added the heated room concept, and built a certification empire around it.

His teacher training program, which ran from the 1990s through the 2010s, required candidates to complete a 9-week intensive at a designated location. Graduates received the right to teach the Bikram sequence in affiliated studios. At peak enrollment, his training program graduated hundreds of teachers per session.

In 2017, a Netflix documentary titled Bikram: Yogi, Guru, Predator (released 2019) brought widespread international attention to multiple lawsuits and criminal allegations against Choudhury. He relocated abroad and, as of 2026, has not returned to the United States to face criminal charges. This context is why so many studios dropped the Bikram name and why “26 and 2” became the widely accepted alternative.

Why Is It Called 26 and 2 Yoga?

26 and 2 yoga is named for the exact number of postures and breathing exercises in the original Bikram sequence: 26 poses and 2 pranayama exercises.

The name emerged as a practical and neutral alternative when studios wanted to keep teaching the sequence without associating with Choudhury’s name. It describes the practice by its structure rather than its founder, in the same way “Ashtanga” describes a system by its format rather than the name of the teacher who popularized it in the West.

The two breathing exercises are:

• Pranayama (Standing Deep Breathing): practiced at the very start of class, standing tall, using a two-part inhale through the nose and a controlled exhale through the mouth, designed to warm the lungs and establish breath awareness
• Kapalbhati (Breath of Fire / Blowing in Firm Pose): performed near the end of class in a seated position, using sharp forceful exhales to engage the abdominals and stimulate the nervous system

The name “26 and 2” has been embraced particularly strongly in North America and Australia. Teacher trainers who were previously Bikram-certified now offer 26 and 2 teacher training programs, deliberately branding their credentials around the sequence format rather than the founder’s name.

Key Takeaway: “26 and 2” is a rebranding choice, not a new practice. The sequence is identical to Bikram yoga. Studios use it because it describes the practice without carrying a contested personal name.

What Is Hot 26 Yoga?

Hot 26 is an informal shorthand for the same 26-pose sequence practiced in a heated room, used primarily by boutique studios and online yoga platforms that want a clean, memorable brand name.

It is not a distinct practice. There is no governing body called the “Hot 26 Association” and no separate certification. Teachers who lead hot 26 classes are almost always trained in the original 26 and 2 sequence through a former Bikram teacher or one of the independent 26 and 2 training programs that have emerged since 2018.

Some studios use “hot 26” because the name is intuitive for new students: the number 26 signals the fixed sequence and “hot” signals the heated room. It removes ambiguity that “hot yoga” alone would create, since hot yoga could refer to any heated class.

Here is a quick comparison of the three most common names:

What Are the 26 Poses in Bikram Yoga?

The 26-pose Bikram sequence follows a fixed anatomical progression: standing poses first, floor poses second, with Savasana (Corpse Pose) used as a recovery pose between each floor posture.

The sequence is designed to work the body systematically from the outside in. Standing poses build heat and strengthen the large muscle groups. Floor poses decompress the spine and stimulate the organs. Each pose is performed twice with a brief rest in between.

Here are the 26 poses in order, with Sanskrit name first and English name in parentheses:

Modification for beginners: During floor poses, it is acceptable to skip the second set if the body is fatigued or overheated. Sitting out a pose in Savasana is always a valid option and is explicitly encouraged in traditional Bikram teaching.

Key Takeaway: The 26-pose sequence is fixed and always runs in this exact order. Each pose serves a specific anatomical function, and knowing what each one targets helps you understand why the sequence works the way it does.

The Science Behind Bikram Yoga

The science behind Bikram yoga centers on three main physiological mechanisms: thermoregulation, cardiovascular challenge, and musculoskeletal effects of heat on flexibility.

The heated room raises your core temperature. Your body responds by increasing blood flow to the skin, raising your heart rate, and activating your sweat response. This places a genuine cardiovascular demand on the body, even during poses that look static from the outside.

A study published in the International Journal of Yoga found that a single 90-minute Bikram session raised participants’ core temperature by approximately 1°C and produced heart rate responses comparable to moderate-intensity aerobic exercise. This means the heat itself is doing physiological work, independent of the yoga poses.

The heat also affects synovial fluid, the lubricating fluid in your joints. Warmer synovial fluid has lower viscosity, meaning joints move more freely and with less resistance. This is why practitioners often notice greater range of motion in a heated room than in a standard studio. However, this increased range can also lead to overstretching if you push beyond your natural end range.

According to the American College of Sports Medicine (ACSM), exercising in the heat increases cardiovascular strain for the same workload compared to a cooler environment. This is not inherently dangerous for healthy adults, but it is a real physiological fact that beginners and people with cardiovascular conditions need to account for before stepping into a 40°C room.

A study published in Complementary Therapies in Medicine found that regular Bikram practitioners showed improved cardiovascular efficiency, reduced resting heart rate, and better glucose regulation compared to sedentary controls over a 16-week period.

Health Benefits of Bikram Yoga

The health benefits of Bikram yoga span cardiovascular fitness, flexibility, stress reduction, and metabolic health, with growing research support across all four categories.

The most consistent research finding involves flexibility and spinal mobility. A 2013 study published in the Journal of Strength and Conditioning Research found that an 8-week Bikram yoga intervention produced measurable improvements in lower back and hamstring flexibility, shoulder range of motion, and overall muscular endurance.

Key documented benefits include:

• Cardiovascular conditioning: moderate aerobic stimulus from the heat-induced heart rate elevation
• Improved flexibility: particularly in the hamstrings, hip flexors, thoracic spine, and shoulders
• Core strength: multiple poses in the sequence directly target the deep core stabilizers, including Tuladandasana (Balancing Stick Pose) and the Pranayama Series
• Stress reduction: the structured format and heat appear to activate the parasympathetic nervous system post-practice, reducing cortisol levels in several small studies
• Glucose regulation: early-stage research from the International Journal of Yoga suggests regular hot yoga may support insulin sensitivity
• Bone density: standing balance poses like Tadasana (Tree Pose) and Garudasana (Eagle Pose) load the hip joint and femur, which may support bone density in older adults
• Mental focus: the discipline of a fixed sequence in a challenging environment has been associated with improved attention and reduced anxiety symptoms in practitioner surveys

The NCCIH acknowledges yoga broadly as beneficial for chronic pain, stress, and sleep quality, though it notes that hot yoga specifically requires more large-scale clinical research to make definitive outcome statements.

Bikram Yoga vs. Hot Yoga: Are They the Same?

Bikram yoga and hot yoga are not the same thing, though Bikram yoga is always a form of hot yoga.

Think of it this way: all squares are rectangles, but not all rectangles are squares. All Bikram yoga is hot yoga, but hot yoga is a much broader category that includes any heated yoga class regardless of style or sequence.

Here is where they differ specifically:

The fixed scripted dialogue is one of the most distinctive features of the original format. Bikram-trained teachers use an almost identical verbal script in every class, worldwide. This is by design: the founder intended every class to feel the same anywhere in the world.

General hot yoga classes do not use a script. They feel more like a typical yoga class, just warmer.

Key Takeaway: Bikram yoga and hot yoga are related but not interchangeable. If you want the exact same 26-pose sequence every class with no variation, you want 26 and 2 or Bikram yoga. If you want variety and flexibility in class style, general hot yoga covers a much wider range.

What Temperature Is Hot Yoga?

Hot yoga temperature varies by style, but the Bikram/26 and 2 standard is specifically 40°C (104°F) with 40% relative humidity.

General hot yoga classes typically run between 32°C and 37°C (90°F to 98°F), which feels warm but is notably less intense than the Bikram specification. Some infrared-heated studios run lower temperatures, around 32°C to 36°C, because infrared heat warms the body from within and feels more intense than conventional air-based heating at the same temperature reading.

The ACSM recommends that exercisers in heated environments monitor for signs of heat stress. Drinking 500ml to 1 liter of water before class and continuing to hydrate throughout is a standard guideline, though exact recommendations vary by body weight and sweat rate.

Here is a temperature comparison by style:

Modification for heat sensitivity: Practitioners who feel dizzy, nauseous, or excessively fatigued should sit in Savasana (Corpse Pose) immediately and drink water. Leaving the heated room briefly is always acceptable and is the safest response to early heat stress symptoms.

Bikram Yoga Training: What Certification Involves

Bikram yoga training in 2026 refers primarily to 26 and 2 teacher training programs, as the original Bikram Choudhury certification structure dissolved following his departure from the United States.

The original Bikram Teacher Training ran as a 9-week residential intensive, held twice annually in a hotel ballroom, typically in Los Angeles or Las Vegas. Participants practiced the sequence twice daily, attended lectures on anatomy and yoga philosophy, and memorized the scripted dialogue. Graduation required demonstrating the full class dialogue from memory.

Today, multiple independent certification programs offer 26 and 2 training, typically structured as:

• Residential intensive format: 7 to 9 weeks, immersive, similar to the original structure
• Hybrid format: in-person intensives combined with online anatomy and philosophy modules
• Duration: Most programs run 200 to 300 hours
• Yoga Alliance recognition: Many newer 26 and 2 programs are now registered with Yoga Alliance as 200-hour or 300-hour RYT programs, giving graduates globally recognized credentials

Yoga Alliance notes that registered teacher training programs must meet curriculum standards covering anatomy, physiology, yoga philosophy, teaching methodology, and practicum hours regardless of the yoga style.

Graduates of these programs can typically teach at any hot yoga or 26 and 2 studio globally. The dialogue-memorization requirement remains common even in post-Bikram programs, as the fixed script is considered central to the practice’s consistency.

Who Should Avoid Hot Yoga?

Certain people should approach hot yoga with real caution or avoid it entirely, and this is one area where honest guidance is genuinely useful.

The American College of Sports Medicine identifies high heat environments as contraindicated for people with:

• Uncontrolled hypertension: the cardiovascular load of heat plus exercise can spike blood pressure
• Cardiovascular disease or arrhythmias: the heat-induced heart rate increase adds stress to an already challenged system
• Heat intolerance conditions: including multiple sclerosis, where heat can temporarily worsen neurological symptoms
• Pregnancy: particularly in the first trimester, where elevated core temperature has been associated with neural tube risk; anyone who is pregnant should discuss hot yoga participation with their obstetric care provider before continuing
• History of heat stroke or hyperthermia: prior episodes increase vulnerability to recurrence
• Severe dehydration or recent illness: electrolyte imbalance combined with a 40°C room is high-risk

People who may participate with modifications:

A key safety note: Feeling dizzy, lightheaded, or nauseous during a hot yoga class is a signal to stop immediately. Sitting in Savasana (Corpse Pose) on the mat, drinking water, and stepping outside the heated room if needed are all appropriate responses. No yoga pose is worth pushing through heat stress.

Key Takeaway: Hot yoga is safe for most healthy adults, but the heat itself adds real physiological load. Anyone with cardiovascular conditions, heat intolerance, or who is pregnant should get specific medical guidance before starting, not a general “check with your doctor” brush-off.

Frequently Asked Questions About Hot Yoga Name

What is hot yoga officially called?

Hot yoga has no single official name; it is a category, not one specific style.
The most structured form within that category is Bikram yoga, also called 26 and 2 yoga or hot 26, which all refer to the same 26-pose sequence practiced at 40°C.
The name on a studio’s schedule usually reflects that studio’s history and teacher training background.

Is Bikram yoga the same as hot yoga?

Bikram yoga is a specific form of hot yoga, but hot yoga is a much broader category.
Bikram yoga always uses the same 26-pose sequence at exactly 40°C for 90 minutes; general hot yoga can use any sequence at temperatures from 32°C to 40°C.
If a studio offers both, they are different classes with different structures.

Why do studios call it 26 and 2 instead of Bikram yoga now?

Studios rebranded from Bikram to 26 and 2 following widely reported criminal allegations and civil lawsuits against founder Bikram Choudhury, which became internationally prominent after 2017.
The name 26 and 2 describes the practice by its structure, 26 poses and 2 breathing exercises, without referencing the founder.
The sequence itself is unchanged; only the name and the institutional affiliation are different.

What are the health benefits of doing Bikram yoga regularly?

Regular Bikram yoga practice has been associated with improved flexibility, cardiovascular conditioning, core strength, and stress reduction in multiple peer-reviewed studies.
A 2013 study published in the Journal of Strength and Conditioning Research found measurable flexibility and endurance improvements after an 8-week Bikram intervention.
Long-term benefits also include improved balance, better glucose regulation, and reduced resting heart rate in practitioners studied over 16 weeks.

Can beginners do Bikram yoga safely?

Yes, beginners can do Bikram yoga safely with the right preparation.
Arrive well-hydrated, eat lightly at least 2 hours before class, bring a large water bottle and a microfiber towel, and give yourself permission to sit in Savasana (Corpse Pose) whenever you need to.
The fixed sequence means beginners see the same poses every class, which makes it easier to learn the alignment progressively rather than following a constantly changing flow.

Start Simple, Stay Consistent

The best place to start is one class. Not a goal to do it five times a week, not a commitment to master the full 90 minutes on day one. One class, hydrated, without judgment.

Bring a towel. Drink water before you go in. Know that the first class will likely feel overwhelming and that is completely normal. The heat, the sequence, and the room all get more familiar with repetition.
