How Many Calories Does Yoga Really Burn?
Yoga calorie burn depends almost entirely on the style. A 150-pound person burns roughly 130 calories in a 60-minute slow hatha class but closer to 250 in the same hour of hot yoga, because hot and power styles keep your heart rate elevated while restorative styles are built around long, still holds. This calculator uses MET (metabolic equivalent) values straight from the Compendium of Physical Activities so the numbers reflect real research rather than a flat one-size-fits-all guess.
The Formula Behind the Numbers
Calorie burn for any activity comes from your body weight, the intensity of the activity, and how long you do it. We convert your weight to kilograms, multiply by the MET value for your chosen style, and scale by your session length in hours.
Calories = METs x weight(kg) x (minutes / 60)
The MET values we use are 2.3 for restorative and yin, 2.5 for slow hatha, 3.3 for vinyasa flow, 4.0 for power and ashtanga, and 5.0 for hot or Bikram yoga. So a 160-pound (72.6 kg) practitioner doing 45 minutes of power yoga burns about 4.0 x 72.6 x 0.75, or roughly 218 calories.
Why Hot Yoga Burns More
The calorie bump in a hot room comes mostly from sustained movement and a higher heart rate, not the heat itself. You sweat far more, which can drop scale weight temporarily, but most of that is water you will replace by your next glass. The lasting benefit is the genuinely higher MET intensity of the continuous flow, which is why power and hot styles land in cardio range while a yin class stays closer to a gentle stretch.
Frequently Asked Questions
Does yoga burn enough calories for weight loss?
Vinyasa, power, and hot yoga can burn 200 to 400 calories per hour, which contributes meaningfully to a calorie deficit. Restorative and yin styles burn far less, so they are better seen as stress relief and recovery than as a primary fat-loss tool.
Why does the hot yoga number look high?
Hot yoga uses a higher MET value because the continuous movement and elevated heart rate genuinely raise energy expenditure. Note that a chunk of the weight you lose during class is sweat, which returns as soon as you rehydrate, so the calorie figure is the real takeaway, not the scale.
Is the calorie estimate accurate for me?
It is a solid research-based estimate using your body weight and a published MET value for each style. Your true burn varies with fitness level, how vigorously you flow, and how long you hold poses, so treat the result as a reliable ballpark rather than a lab measurement.
Should I count yoga calories when tracking my deficit?
Yes, but conservatively. Logging your session burn is fine, though most fitness trackers and apps already fold light activity into your daily total, so avoid double-counting if your tracker is also crediting the same session.
Practical Guide for Yoga Calorie Calculator
The biggest lever on your yoga calorie burn is style, not effort within a single class. Switching from a restorative session to a vinyasa flow can nearly double the burn for the same time on the mat, so if calories are a goal, choose a flowing or heated format and save yin for recovery days.
Length matters in a roughly linear way because the formula scales by minutes. A 90-minute power class burns about 50 percent more than the same style for 60 minutes, which is why many studios offer longer power and ashtanga sessions while keeping restorative classes shorter and slower.
Consistency beats intensity over a month. Three steady vinyasa sessions a week add up to a respectable weekly burn that compounds, and unlike high-impact cardio, yoga is gentle enough on joints that you can practice often without the recovery cost of running or heavy lifting.
Quick Checklist
- Pick the style that matches your goal: flow or hot for calories, yin or restorative for recovery.
- Log your actual minutes, including warm-up and savasana, for the most realistic estimate.
- Hydrate well before and after hot yoga so sweat loss does not mislead you on the scale.
- Pair regular yoga with a modest calorie deficit if your aim is steady fat loss.
