Calories Burned from Yoga:

How yoga calorie burn is calculated
This calculator uses the MET (Metabolic Equivalent of Task) formula. A MET is a multiple of resting energy expenditure — 1 MET is what you burn sitting quietly. The MET values come from the Compendium of Physical Activities, the reference compiled by Ainsworth and colleagues from indirect calorimetry studies.
Calories = MET × Weight (kg) × Duration (hours)
The MET value used depends on the style and intensity:
| Style | Intensity setting | MET |
|---|---|---|
| Hatha, gentle, yin, restorative | Light | 2.5–2.8 |
| Iyengar, alignment-focused, slow vinyasa | Moderate | 3.0–3.3 |
| Vinyasa flow, power yoga | Intense | 4.0 |
| Ashtanga, bikram (hot yoga) | (beyond "intense") | 5.0+ |
Worked example with the calculator defaults
The calculator opens with a 50 kg person doing 30 minutes of moderate yoga (MET 3.3):
- Calories = 3.3 × 50 × 0.5 = 83 calories.
- Switching to "Intense" (MET 4.0) bumps that to 100 calories. Switching to "Light" (MET 2.8) drops it to 70.
That's a 30-calorie spread for the same 30 minutes, depending only on the style. For a typical 60-minute class for a 75 kg adult, the same spread is roughly 190 (hatha) to 300 (vinyasa) calories.
Calories burned by yoga style and body weight
Per 60-minute session, with MET values drawn from the Compendium:
| Style | MET | 60 kg (132 lb) | 75 kg (165 lb) | 90 kg (198 lb) |
|---|---|---|---|---|
| Hatha, gentle | 2.5 | 150 cal | 188 cal | 225 cal |
| Iyengar / slow vinyasa | 3.3 | 198 cal | 248 cal | 297 cal |
| Vinyasa / power | 4.0 | 240 cal | 300 cal | 360 cal |
| Ashtanga / bikram | 5.0 | 300 cal | 375 cal | 450 cal |
For perspective: an hour of running at a 10-min/mile pace burns roughly 700–900 cal for the same 75 kg person. Yoga is not in that league for raw calorie expenditure, and pretending otherwise sets up a disappointing comparison. Choose yoga for what it actually does well — mobility, breath control, stress regulation — and treat the calorie number as a bonus.
Limitations of this calculator
The MET model handles steady-state activity well but bumps against several yoga-specific complications:
- One MET per style is a coarse average. A 60-minute vinyasa class might contain 15 minutes of warm-up at 2.5 MET, 30 minutes of flowing sequences at 4.5 MET, and 15 minutes of savasana at 1.0 MET. Reducing that to "vinyasa = 4.0" obviously loses detail.
- Held postures inflate perceived effort. Holding warrior II for 90 seconds feels brutal but consumes relatively little oxygen. The calorie burn from a long hold is small; the strength stimulus may not be.
- Breath work doesn't show up. Pranayama and meditation sessions burn close to resting metabolic rate. The calculator will give you a number, but the value of those practices isn't in calories.
- Hot yoga and bikram are harder to model. The heat raises heart rate and sweat loss without proportionally raising calorie burn. People often overestimate how much they burned in a hot class because of how the session feels.
- Individual variation is large. Flexibility, body composition, and how much active engagement you bring to each pose can swing actual burn by 20–30% above or below the calculator's number.
For most practitioners, the right framing is: yoga is a meditation in motion that incidentally burns 150–400 calories per hour. The calorie number isn't why yoga works.

FAQs
It depends heavily on the style. Hatha and restorative yoga sit around 2.5 MET — a 75 kg adult burns roughly 190 calories per hour. Vinyasa or power yoga is closer to 4.0 MET, or about 300 cal/hr for the same person. Ashtanga and bikram (hot yoga) push toward 5.0 MET, or 375 cal/hr. The popular "yoga burns 500 calories an hour" claim only applies to the most vigorous styles and a heavier person.
Only slightly. Studies measuring oxygen consumption in heated rooms (around 40 °C / 105 °F) find that the heat itself adds maybe 10–15% to calorie burn versus the same poses at room temperature. The bigger drivers are how dynamic the sequence is and how long you hold poses. The heat does raise heart rate substantially, which is why hot yoga can feel harder than the calorie number suggests — cardiovascular strain doesn't always correlate with energy expenditure.
For most people, no — not without a calorie deficit through diet. A 75 kg adult doing 60 minutes of vinyasa burns about 300 calories. Six sessions a week is 1,800 calories, less than the deficit needed for half a pound of weight loss. Yoga supports weight loss best by improving stress resilience and sleep (both of which affect appetite regulation) rather than by direct calorie burn. Pair it with diet changes or a higher-intensity activity for actual fat loss.
Roughly in order from highest to lowest: ashtanga and power vinyasa (5.0–5.5 MET), bikram / hot yoga (4.5–5.0 MET), vinyasa flow (3.5–4.0 MET), iyengar (3.0 MET), hatha (2.5 MET), yin and restorative (2.0–2.3 MET). But the highest-calorie style is the one you'll actually do consistently. A sustained hatha practice will outperform an abandoned ashtanga goal.
Most wrist-worn trackers estimate calorie burn from heart rate and movement. Yoga confounds both: held poses register as minimal movement, and breath-controlled heart rate spikes can read as exertion even when oxygen consumption is low. Trackers tend to under-count flowing styles (because of slow tempo) and over-count held postures (because of elevated heart rate). The MET-based estimate from a calculator is usually closer to lab-measured values for steady-state yoga.
