Ashtanga yoga is a dynamic, flowing practice that links breath with movement through a set sequence of postures. Because it is continuous and physically demanding, it burns significantly more energy than gentle or restorative yoga. This calculator estimates the calories you burn during an Ashtanga session using the Metabolic Equivalent of Task (MET) value of 5.0, which is the standard figure used in exercise science for vigorous yoga.
Simply enter your body weight, the duration of your practice, and choose your preferred unit system. The tool instantly shows your estimated calories burned, along with a breakdown of the calculation and a comparison to other common activities. Whether you are tracking your daily energy expenditure, planning a weight-management routine, or just curious about your practice, this calculator gives you a quick, evidence-based estimate.
Use the preset buttons to quickly try common session lengths, or adjust the sliders to match your exact practice. The result updates instantly as you change any input.

Estimate calories burned during your Ashtanga practice
How to Use This Tool
Using the Ashtanga MET calculator is straightforward. Start by entering your body weight in either kilograms or pounds — the calculator converts automatically. Then enter the duration of your practice, either in minutes or hours. You can use the quick-duration buttons to instantly set common session lengths like 30, 45, 60, or 90 minutes. After clicking Calculate, you'll see your estimated total calories burned, along with a detailed breakdown showing the MET value used, your weight in kilograms, the duration in minutes, and your calories per minute.
For the most accurate estimate, use your current body weight and the actual time you spent actively practicing. If you take long breaks during your session, consider entering only the active time. The calculator is designed for adults and uses the standard MET value for Ashtanga yoga, so it works well for most healthy individuals.
How It Works
The calculation is based on the Metabolic Equivalent of Task (MET) system, which expresses the energy cost of physical activities as a multiple of resting metabolic rate. One MET is roughly the energy you burn while sitting quietly, about 1 kcal per kilogram of body weight per hour. Ashtanga yoga has a MET value of 5.0, meaning it burns about five times more energy than resting.
The formula used is:
Calories burned = MET × weight (kg) × duration (hours)
For example, a 70 kg person practicing for 60 minutes would burn:
5.0 × 70 × 1 = 350 kcal
This MET value comes from the Compendium of Physical Activities, a widely used research resource that assigns MET values to hundreds of activities. The value of 5.0 corresponds to "yoga, Ashtanga" and is considered a vigorous-intensity activity.
Worked Examples
Let's walk through a few scenarios to see how the calculator works in practice.
Example 1: A 60 kg woman practices Ashtanga for 45 minutes.
Weight: 60 kg, Duration: 0.75 hours
Calories = 5.0 × 60 × 0.75 = 225 kcal
Example 2: A 180 lb man practices for 90 minutes.
Weight: 180 lb = 81.6 kg, Duration: 1.5 hours
Calories = 5.0 × 81.6 × 1.5 = 612 kcal
Example 3: A 55 kg person practices for 30 minutes.
Calories = 5.0 × 55 × 0.5 = 137.5 kcal
These examples show how both weight and duration directly affect the result. Heavier individuals burn more calories because they require more energy to move their body through the postures.
Factors Affecting Accuracy
While the MET method provides a solid estimate, actual calorie burn can vary from person to person. Your fitness level plays a role — experienced practitioners often move more efficiently and may burn slightly fewer calories than beginners doing the same sequence. The intensity of your practice also matters; a slow, deliberate session may be closer to a MET of 4.0, while a fast, powerful practice could reach 6.0 or higher.
Other factors include your age, gender, muscle mass, and even room temperature. The calculator uses a standard MET value, so treat the result as a good baseline rather than an exact measurement. For precise tracking, consider using a heart rate monitor or a fitness tracker that accounts for your individual physiology.
Tips & Best Practices
To get the most out of this calculator, use it consistently. Track your weight regularly and update the input to reflect any changes. If you practice Ashtanga several times a week, you can sum the results to estimate your weekly calorie expenditure from yoga. This can be useful for weight management or for balancing your overall activity level.
Remember that Ashtanga is a full-body workout that also builds strength, flexibility, and mental focus. The calorie burn is just one benefit.

Frequently Asked Questions
Is Ashtanga yoga good for weight loss? Yes, because it burns a significant number of calories and builds lean muscle, which can boost your metabolism. However, weight loss also depends on your overall diet and other physical activity.
How does Ashtanga compare to other yoga styles? Ashtanga is more vigorous than Hatha or restorative yoga, so it burns more calories per minute. For example, gentle yoga has a MET of about 2.5, while Ashtanga is 5.0 — double the energy expenditure.
Can I use this calculator for other yoga styles? No, because different styles have different MET values. Use a calculator specific to the style you practice for the most accurate estimate.
Why is my result different from my fitness tracker? Fitness trackers use algorithms based on heart rate and movement, which can be more or less accurate depending on the device. The MET method is a standardized estimate, so small differences are normal.
