Bikram yoga, often called hot yoga, is practiced in a room heated to about 105°F (40°C) with 40% humidity. The heat increases heart rate and metabolic demand, so you burn more calories than in a typical room-temperature yoga class. This calculator estimates the calories you burn during a standard 45-minute Bikram session based on your body weight and the intensity of your practice.
Whether you're tracking your fitness goals, planning a weight-loss program, or simply curious about your energy expenditure, this tool gives you a quick, science-based estimate. It uses the Metabolic Equivalent of Task (MET) values from the Compendium of Physical Activities, adjusted for the unique demands of hot yoga. Simply enter your weight, choose your intensity level, and click calculate to see your estimated calories burned.
🧘♀️ Bikram Yoga Calorie Burn
Formula: Calories = MET × weight (kg) × duration (hours)
MET values: Light = 4.0, Moderate = 5.0, Vigorous = 6.0

How to Use This Tool
Using the Bikram Calories Per 45 Minutes Calculator is straightforward. Start by entering your body weight in either kilograms or pounds — the calculator automatically converts pounds to kilograms for the formula. Then select your intensity level: Light for a gentle, beginner-friendly class; Moderate for a typical Bikram session where you're working steadily; or Vigorous for an advanced class with maximum effort and minimal rest.
Click Calculate to see your estimated total calories burned for the 45-minute session, along with a per-minute rate and an extrapolated per-hour figure. The breakdown section shows the exact formula used, so you can verify the math. Use the quick-fill buttons to instantly populate common weights, or reset to clear everything and start fresh.
How It Works
This calculator uses the Metabolic Equivalent of Task (MET) method, the standard approach in exercise science for estimating energy expenditure. One MET is the energy cost of sitting quietly, roughly 1 kcal per kilogram of body weight per hour. During physical activity, your body expends multiple METs depending on intensity.
The formula is:
Calories burned = MET value × body weight (kg) × duration (hours)
For Bikram yoga, we use MET values from the Compendium of Physical Activities: 4.0 METs for light effort, 5.0 METs for moderate effort, and 6.0 METs for vigorous effort. These values account for the added cardiovascular load from the heated environment, which raises heart rate and metabolic rate compared to room-temperature yoga.
For a 45-minute session, the duration is 0.75 hours. So a 70 kg person practicing at moderate intensity would burn approximately 5.0 × 70 × 0.75 = 262.5 kcal.
Worked Examples
Example 1: A 60 kg woman takes a moderate Bikram class. Calories = 5.0 × 60 × 0.75 = 225 kcal.
Example 2: A 180 lb man (about 81.6 kg) practices vigorously. Calories = 6.0 × 81.6 × 0.75 = 367.2 kcal.
Example 3: A 50 kg beginner does a light session. Calories = 4.0 × 50 × 0.75 = 150 kcal.
Factors Affecting Accuracy
While MET-based estimates are useful, individual calorie burn can vary significantly. Key factors include:
- Body composition: Muscle tissue burns more calories than fat, even at rest. A person with higher muscle mass may burn more.
- Age and gender: Metabolic rate naturally declines with age, and men often have higher muscle mass and burn more.
- Fitness level: Experienced practitioners may move more efficiently, but they also tend to push harder, which can increase burn.
- Room temperature and humidity: The heat of Bikram studios increases sweat and cardiovascular strain, but the exact effect varies by individual.
- Actual effort: The MET values assume a consistent effort level. If you take frequent breaks or modify poses, your burn will be lower.
For the most accurate measurement, consider using a heart rate monitor or a fitness tracker that accounts for your personal data.
Tips & Best Practices
- Stay hydrated: Bikram yoga causes significant fluid loss through sweat. Drink water before, during, and after class.
- Listen to your body: The heat can be intense. If you feel dizzy or nauseous, take a break. Safety comes first.
- Combine with other activities: For weight loss, pair Bikram with a balanced diet and other forms of exercise like walking or cycling.
- Track your progress: Use this calculator regularly to see how your calorie burn changes as your weight and intensity evolve.
Frequently Asked Questions
Is Bikram yoga good for weight loss?
Yes, Bikram yoga can contribute to weight loss, especially when combined with a calorie-controlled diet. A 45-minute session burns roughly 200–350 kcal depending on your weight and effort, which adds up over time.
How many calories do you burn in a 60-minute Bikram class?
To estimate, simply multiply the 45-minute result by 1.33. For example, a 70 kg person at moderate intensity would burn about 350 kcal in 60 minutes.
Does the heat really increase calorie burn?
The heat raises your heart rate and makes your body work harder to cool itself, which can increase calorie expenditure. However, the effect is modest compared to the intensity of the poses themselves.
Can I use this calculator for other types of yoga?
This calculator is specifically calibrated for Bikram (hot) yoga. For other styles, such as Hatha or Vinyasa, you can use our Hatha yoga calculator or adjust the MET value manually.
