Yoga Energy Expenditure Calculator
Estimate the calories burned during a yoga session based on your body weight, session length, and practice intensity. Use this after class to log energy output for fitness or nutrition planning.
About this calculator
Energy expenditure during yoga is estimated using Metabolic Equivalent of Task (MET) values, which quantify the energy cost of an activity relative to rest. The formula used here is: energyExpenditure (kcal) = (bodyWeight × sessionDuration / 60) × MET, where MET equals 6 for high-intensity styles (e.g., Ashtanga, Power Yoga), 4 for moderate styles (e.g., Vinyasa, Hatha Flow), and 2 for gentle styles (e.g., Yin, Restorative). Body weight is in kilograms and session duration in minutes. This approach is consistent with guidelines from the Compendium of Physical Activities. MET-based estimates are approximations and can vary based on individual fitness level and effort.
How to use
Suppose you weigh 70 kg and completed a 60-minute Vinyasa class (moderate intensity, MET = 4). Enter bodyWeight = 70, sessionDuration = 60, yogaStyle = moderate. The calculator computes: energyExpenditure = (70 × 60 / 60) × 4 = 70 × 4 = 280 kcal. So you burned approximately 280 calories during that session. If you had chosen a Power Yoga class (high intensity, MET = 6), the result would be 70 × 6 = 420 kcal — 140 more calories for the same duration, highlighting how style selection significantly impacts energy output.
Frequently asked questions
How many calories does yoga burn compared to other exercises?
Yoga burns between 120 and 420 calories per hour depending on style and body weight, placing it below running (400–600 kcal/hr) but comparable to brisk walking or light cycling. Restorative and Yin yoga have very low MET values (~2) since they involve prolonged passive holds. Hot yoga adds a heat-stress factor that slightly elevates heart rate and calorie burn beyond standard estimates. For significant caloric expenditure, Power Yoga or Ashtanga are the most effective yoga styles, but all forms offer benefits beyond simple calorie burn, including flexibility, stress reduction, and mindfulness.
What yoga style burns the most calories per session?
High-intensity styles such as Ashtanga, Power Yoga, and Hot Vinyasa burn the most calories, with MET values around 5–7. A 75 kg person practicing Ashtanga for 90 minutes can expend approximately 530–660 kcal. These styles combine continuous movement, strength-demanding poses, and cardiovascular engagement. Bikram or hot yoga can slightly inflate calorie estimates due to heat-induced heart rate increases, though much of the weight lost is water. If calorie burn is a primary fitness goal, pairing a high-intensity yoga style with strength or cardio training is typically recommended.
Is the MET-based yoga calorie formula accurate for everyone?
MET-based calculations provide a reasonable population-level estimate but carry an uncertainty of roughly ±15–20% for individuals. Factors not captured include your current fitness level, muscle mass, age, hormonal state, and how vigorously you personally engage in each pose. Heavier individuals generally burn more calories per session, and conditioned athletes may burn fewer because their bodies are more efficient. For the most accurate measurement, a heart rate monitor with a VO₂ max estimate or a lab metabolic test would be needed. Use this calculator as a practical guide rather than a precise medical measurement.
