Bikram yoga is a demanding 90-minute sequence practiced in a room heated to about 105°F (40°C) with 40% humidity. The heat raises your heart rate and metabolic rate, so you burn more calories than in a typical room-temperature yoga class. This calculator estimates how many calories you burn during a 60-minute Bikram session based on your weight, age, gender, and exercise intensity.
Whether you're tracking your fitness goals, planning your nutrition, or just curious about the energy cost of your practice, this tool gives you a science-based estimate using the standard MET (Metabolic Equivalent of Task) formula. It's designed for Bikram practitioners, yoga teachers, and anyone exploring gentle yet intense movement. Simply enter your details, adjust the intensity to match your effort, and get an instant calorie estimate for your next 60-minute class.

How to Use This Calculator
Enter your weight (in kilograms or pounds), your age, and select your gender. Then choose an intensity level that matches your typical Bikram class: Light for a gentle, beginner-friendly session; Moderate for a standard class with steady effort; or Vigorous for an advanced, high-effort practice. Click Calculate to see your estimated calorie burn for a full 60-minute session, along with a per-minute rate and a breakdown of the calculation.
You can use the quick-fill buttons to instantly load common weights, or manually type your own. The reset button clears all inputs and results.
How the Calculation Works
This calculator uses the standard MET (Metabolic Equivalent of Task) formula, which is widely used in exercise science to estimate energy expenditure:
Calories per minute = MET × 3.5 × weight (kg) / 200
For a 60-minute session, we multiply the per-minute value by 60.
MET values represent the energy cost of an activity relative to resting metabolism. For Bikram yoga, we use the following MET values based on typical intensity levels:
- Light: 4.0 METs (gentle, beginner pace)
- Moderate: 5.0 METs (typical class effort)
- Vigorous: 6.0 METs (advanced, high effort)
We also apply two adjustments to make the estimate more personal: an age factor (metabolic rate gradually declines with age) and a gender factor (women typically have slightly lower resting metabolic rates than men of the same weight). These adjustments are based on common physiological trends and help refine the estimate.
Worked Examples
Example 1: A 30-year-old woman weighing 65 kg practices a moderate Bikram class.
MET = 5.0, weight = 65 kg, age factor = 1 - (30-25)×0.002 = 0.99, gender factor = 0.9
Calories = 5.0 × 3.5 × 65 / 200 × 60 × 0.99 × 0.9 ≈ 304 kcal
Example 2: A 45-year-old man weighing 180 lb (about 81.6 kg) takes a vigorous class.
MET = 6.0, weight = 81.6 kg, age factor = 1 - (45-25)×0.002 = 0.96, gender factor = 1.0
Calories = 6.0 × 3.5 × 81.6 / 200 × 60 × 0.96 ≈ 494 kcal
Factors That Affect Your Calorie Burn
Several variables influence how many calories you actually burn during a Bikram session:
- Body weight: Heavier individuals burn more calories because moving a larger body requires more energy.
- Muscle mass: People with more muscle have a higher resting metabolic rate and burn more during exercise.
- Effort level: How hard you push yourself in each posture dramatically changes the energy cost. A vigorous practice can burn 20–30% more than a gentle one.
- Room temperature and humidity: The heat of Bikram increases heart rate and sweat rate, which can raise calorie burn, but the effect varies by individual.
- Fitness level: Highly conditioned individuals may become more efficient and burn slightly fewer calories for the same movement, though they can often sustain higher intensity.
Tips for Accurate Tracking
Weigh yourself in the morning before eating for the most consistent baseline. Use the same unit (kg or lb) each time. If you're using a fitness tracker, note that wrist-based devices often overestimate calorie burn during hot yoga because they rely on heart rate and movement, not core temperature. For the most reliable estimate, combine this calculator with your own perceived exertion and adjust the intensity level accordingly.
Frequently Asked Questions
Is Bikram yoga good for weight loss? Yes, Bikram can contribute to a calorie deficit, especially when combined with a balanced diet. A 60-minute session typically burns 250–500 calories depending on your weight and effort, which is comparable to brisk walking or light cycling.
Why does the heat matter? The heat raises your heart rate and makes your body work harder to cool itself, which can increase calorie burn. However, the primary driver of calorie expenditure is still the muscular work of the postures.
Can I use this for other hot yoga styles? This calculator is specifically calibrated for Bikram's 26-posture sequence. Other styles like Vinyasa or Power Yoga may have different MET values, so results may vary.
How accurate is this estimate? The MET formula is a validated method used in exercise science, but individual variation is significant. Treat the result as a useful guideline, not a precise measurement.
