How Many Calories Does Hot Yoga Burn?
Hot yoga burns roughly 200 to 600 calories in a 60-minute class, depending on your body weight, the style you practice, and how hard you move. Heavier bodies and faster-paced styles like heated vinyasa sit at the higher end of that range. Slower, pose-hold styles like Bikram sit lower than most people expect.
Joga Yoga Training runs daily hot yoga and Vinyasa classes in Canggu, Bali, and built the calculator below because most online estimates skip the two things that actually change your number: your weight and the specific style of class you took. A hot room raises your sweat rate well past a room-temperature class, but sweat by itself does not burn extra calories. Movement does.
This calculator gives you an estimate based on your weight, class length, and yoga style. It is not a lab test. Use it to compare your own sessions over time, not as a medical measurement.
How Many Calories Do You Burn in 60 Minutes of Hot Yoga?
A 60-minute hot yoga class burns an estimated 220 to 500 calories for most adults, based on the only controlled research measuring real energy expenditure during a heated session. The exact number depends heavily on your body weight and sex.
The real research behind this number: Colorado State University researcher Brian Tracy measured actual energy expenditure during 90-minute Bikram yoga sessions and found an average of 460 calories burned for men and 330 calories for women. Body size, not effort alone, explained most of the difference between the two groups. Scaled down to a 60-minute class, that works out to roughly 305 calories for men and 220 calories for women, though a shorter class also means less total heat exposure, not a perfectly straight fraction of the longer session.

Tracy’s team also recorded heart rates averaging 160 beats per minute and core temperatures near 100.3°F during the study, both within a safe range for healthy adults. That heart rate matters for the next section, because it is exactly what makes wearables overstate your burn.

Advanced Metabolic Estimate
Heat raises heart rate on its own, so this mode can run high in a hot room. The style-based estimate below is usually more reliable for heated classes.

What Is MET and How This Calculator Works
MET stands for Metabolic Equivalent of Task. One MET is the energy your body uses at rest. A higher MET number means higher effort, and hot yoga typically carries a higher MET than a room-temperature class because the heat pushes your breathing and heart rate up.
This calculator uses the standard MET formula:
Calories per minute = (MET × 3.5 × weight in kg) ÷ 200
That result is then multiplied by the number of minutes you practiced. MET is the effort level of the style you choose, 3.5 is a fixed constant used in every MET calculation, weight in kg is your body weight, and 200 is part of the standard conversion.
MET values for yoga styles vary between sources, since room heat, pace, and how much a given class actually moves are not identical from studio to studio. The Metabolic Equivalent framework itself comes from the Compendium of Physical Activities, the standard reference researchers use to compare activities. This calculator applies its own MET assumptions per style rather than a single fixed number, which is why your result changes when you switch between Bikram, heated vinyasa, and power yoga.
Two people in the same class can still burn a different number of calories because of effort, fitness level, and how much they actually move through each pose. Use the calculator to compare your own sessions against each other. That is where it is most useful.
Bikram vs Heated Vinyasa: Which Burns More Calories?
Heated vinyasa usually burns more calories than Bikram because it keeps you moving continuously, while Bikram holds you in fixed postures for longer stretches with pauses in between.
Why Heated Vinyasa Usually Burns More
Heated vinyasa classes move from one pose to the next with the breath, without long pauses. That keeps your heart rate elevated for longer and cuts down on rest between poses, which raises total energy use across the class.
Why Bikram Can Burn Fewer Calories Than Expected
Bikram yoga follows a fixed sequence of 26 postures, and most of them are held rather than flowed through. Heart rate rises and falls with each posture instead of staying elevated, so the body leans more on endurance than continuous cardio work. The heat in a Bikram room increases sweating, but sweating alone does not raise your calorie burn.
Myth vs fact: Sweating more does not mean burning more calories. Heat increases water loss. It does not increase energy use on its own.
Why Your Fitness Tracker Shows a Different Number Than the Calculator
Your smartwatch likely overstates your hot yoga calorie burn because it estimates calories from heart rate, and heat raises heart rate on its own, independent of how much muscle work you are actually doing.
Stanford Medicine researchers tested seven popular wearables against lab-grade measurements and found the devices measured heart rate accurately, within about 5 percent, but their calorie estimates were off by 27 to 93 percent depending on the device. (Stanford Medicine) A heated room pushes that error higher still, since your watch cannot tell the difference between a heart rate spike from movement and one from your body working to cool itself.
This explains a pattern you have probably seen in class: two people doing the identical 60-minute session walk out with wildly different numbers on their wrists, sometimes 200 calories apart, even though they moved through the same sequence at a similar pace. The gap is not really about you. It is about what the device is measuring.
Dehydration compounds the confusion. The number on the scale often drops right after a hot yoga class, but that drop is water loss from sweat, not fat loss, and it returns once you rehydrate.
Is Hot Yoga Effective for Weight Loss?
Hot yoga can support weight loss when you practice it consistently and maintain a calorie deficit over time. It is not a shortcut on its own, and nutrition still matters more than the number the calculator gives you after one class.
In Canggu’s already warm, humid climate, a heated room pushes your sweat rate higher than the same class would in a cooler city. Drink water before class, not only after, if you practice hot yoga in Bali.
How Hot Yoga Supports Fat Loss
Hot yoga increases energy use, especially in flowing styles that keep you moving. It also builds lean muscle through held poses and repeated movement, and more muscle raises your resting metabolism over time. Movement-based practices like this also improve circulation and recovery, which helps you bounce back faster from other workouts.
Stress plays a bigger role in weight management than most people give it credit for. Yoga’s effect on the nervous system can help lower stress-driven eating, which matters more for long-term results than any single class’s calorie count.
Common Mistakes to Avoid
- Eating far more after class than the session burned, which cancels out the deficit
- Treating sweat as a sign of fat loss, when it is mostly water weight
- Judging progress off a single wearable reading instead of consistent practice over weeks
How to Maximize Calorie Burn in Hot Yoga Safely
- Choose flowing styles like heated vinyasa or power yoga if calorie burn is the goal
- Engage your muscles actively instead of relying on flexibility alone to get through a pose
- Hydrate before, during, and after class, not just afterward
- Practice consistently rather than cramming several sessions into a short window
Overheating lowers performance. Pushing too hard in a hot room tends to produce fatigue, not a bigger number.
Hot yoga works best when you pick a style you actually enjoy and can show up for regularly. Some people burn more in flowing classes. Others do better in slower classes that build strength and focus instead. Explore the full range of yoga styles before deciding which one fits your body and your schedule.

Frequently Asked Questions
How many calories does hot yoga burn in 60 minutes?
Most people burn between 220 and 500 calories in a 60-minute hot yoga class, with the exact number shaped by body weight, class style, and how actively you move.
How many calories does a 90-minute Bikram class burn?
Colorado State University’s measured study found men burn about 460 calories and women about 330 calories during a 90-minute Bikram session, with body size accounting for most of the difference.
Does Bikram yoga burn more calories than heated vinyasa?
Usually not. Heated vinyasa tends to burn more because it keeps you moving continuously, while Bikram holds static poses with pauses that let your heart rate drop between postures.
Is hot yoga good for weight loss?
Hot yoga can support weight loss when you practice it regularly and stay in a calorie deficit. It works best as part of a routine, not as a standalone fix.
Why do my fitness tracker and this calculator show different numbers?
Fitness trackers estimate calories from heart rate, and heat raises heart rate on its own. Stanford research found wearables measure heart rate accurately but overstate calorie burn by 27 to 93 percent, and a heated room widens that gap further.
