Bikram yoga, practiced in a room heated to about 105°F (40°C) with 40% humidity, is a demanding 90-minute sequence of 26 postures and two breathing exercises. The heat raises your heart rate and metabolic demand, so you burn more calories than in a typical room-temperature yoga class. This calculator estimates your total calorie burn based on your body weight, session duration, and exercise intensity.
Whether you're a beginner just starting your first 90-minute class or an experienced practitioner doing a double session, this tool gives you a realistic estimate of your energy expenditure. It uses the standard MET (metabolic equivalent) values for Bikram yoga, adjusted for your weight and the actual time you spend on the mat. Use it to track your progress, plan your nutrition, or simply satisfy your curiosity about how much energy a hot yoga session really uses.

How to Use This Calculator
Enter your body weight (in kilograms or pounds) and the length of your Bikram session. The default duration is 90 minutes, which is the standard class length, but you can adjust it for shorter or longer practices. Choose an intensity level that matches your experience: Light for beginners who take frequent breaks or modify postures, Moderate for a typical class where you maintain a steady effort, and Vigorous for advanced practitioners who push through every posture with maximum effort.
Click Calculate to see your estimated calorie burn. The result includes a per-minute rate and the total for the session. You can also use the quick preset buttons to set common class durations (60, 90, or 120 minutes) without typing.
How It Works
The calculation uses the MET (Metabolic Equivalent of Task) system. One MET is the energy cost of sitting quietly, roughly 1 kcal per kilogram of body weight per hour. Physical activities are assigned a MET value based on research. For Bikram yoga, the Compendium of Physical Activities lists a MET value of 4.0 for general yoga, but because of the heat and intensity, many sources estimate Bikram-specific values between 3.5 and 5.5. This calculator uses 2.5 for light, 4.0 for moderate, and 5.5 for vigorous effort.
The formula is:
Calories burned = MET × 3.5 × (weight in kg) ÷ 200 × (duration in minutes)
This is the standard equation used in exercise physiology. It accounts for the fact that heavier individuals burn more calories doing the same activity, and that longer sessions burn more total energy.
Worked Examples
Example 1: A 70 kg (154 lb) person does a 90-minute moderate Bikram class.
Calories = 4.0 × 3.5 × 70 ÷ 200 × 90 = 441 kcal
Example 2: A 60 kg (132 lb) beginner does a 60-minute light session.
Calories = 2.5 × 3.5 × 60 ÷ 200 × 60 = 158 kcal
Example 3: A 90 kg (198 lb) advanced practitioner does a 120-minute vigorous double class.
Calories = 5.5 × 3.5 × 90 ÷ 200 × 120 = 1039 kcal
Factors Affecting Accuracy
This estimate is based on averages and may not match your actual burn. Individual factors include:
- Muscle mass: More muscle increases your basal metabolic rate and calorie burn during exercise.
- Fitness level: Trained individuals often become more efficient, burning slightly fewer calories for the same work.
- Room temperature and humidity: The heat raises your heart rate, but the exact effect varies.
- Effort and posture depth: Holding postures longer or with greater intensity increases the burn.
- Breathing and rest periods: Taking extra breaks lowers the average intensity.
Use this number as a guideline, not a precise measurement. For weight management, focus on consistency and overall energy balance rather than exact per-session numbers.
Tips for Maximizing Your Burn
- Stay hydrated: Drink water before and after class. Dehydration can reduce performance and calorie burn.
- Arrive early: Give your body time to acclimate to the heat so you can put in full effort from the start.
- Focus on form: Proper alignment engages more muscles and increases energy expenditure.
- Minimize breaks: Try to keep moving through the sequence, even if you modify postures.
- Combine with strength training: Building muscle raises your resting metabolism, so you burn more calories even at rest.
Frequently Asked Questions
Is Bikram yoga good for weight loss? Yes, it can contribute to a calorie deficit, especially when combined with a healthy diet. A 90-minute class can burn 300–600 calories depending on your weight and effort.
Why do I feel like I burned more than the calculator says? The heat makes you sweat heavily, but sweat is not a direct measure of calorie burn. The calculator uses physiological data, so it's more accurate than going by sweat alone.
Can I use this for other hot yoga styles? Yes, the MET values are similar for most hot yoga classes. Just adjust the intensity based on how hard you work.
How often should I practice Bikram? Many practitioners attend 3–5 times per week. Listen to your body and allow rest days, especially when starting.
