A standard hour of yoga burns roughly 240 to 500 calories, depending on the style you practice and how much you weigh. A gentle hatha class sits at the lower end, while a fast-paced vinyasa or power session pushes toward the upper range. That’s a wide spread, so the real answer depends on a few specifics worth breaking down.
Calorie Burn by Body Weight
Your body weight is one of the biggest factors in how many calories any exercise burns, and yoga is no exception. Harvard Health Publishing provides estimates for 30 minutes of hatha yoga that scale clearly with size:
- 125-pound person: 120 calories per 30 minutes (roughly 240 per hour)
- 155-pound person: 144 calories per 30 minutes (roughly 288 per hour)
- 185-pound person: 168 calories per 30 minutes (roughly 336 per hour)
These numbers reflect a traditional hatha-style class with held poses and stretching. If you weigh more than 185 pounds, your burn will be proportionally higher. A 220-pound person doing the same class could expect somewhere around 400 calories per hour. The basic math: a heavier body requires more energy to move, stabilize, and hold itself in position.
How Different Yoga Styles Compare
The type of yoga you practice matters as much as your body weight. A slow restorative class and a power vinyasa flow are barely the same activity from a metabolic standpoint.
Hatha yoga burns roughly 150 to 250 calories per hour. It involves holding individual poses with rest periods in between, keeping your heart rate relatively low. An ACE study found that a typical hatha class burned fewer calories than walking at a moderate pace.
Vinyasa yoga links poses together in continuous sequences, which keeps your heart rate elevated for longer stretches. The American Council on Exercise estimates a vinyasa class can burn 400 to 500 calories per hour depending on intensity. That puts it closer to a brisk walk or light jog.
Power yoga is the most physically demanding common style. Research on heart rate responses found that participants spent 78% of a 45-minute power yoga class in moderate-to-vigorous heart rate zones, reaching around 60% of their maximum heart rate. That classifies it as moderate-intensity exercise, comparable to brisk walking in terms of energy cost. Calorie burn rates are similar to vinyasa, in the range of 300 to 450 calories per hour.
Hot yoga (Bikram) often gets credit for extreme calorie burn because of how much you sweat, but the actual numbers are more modest than people expect. A Colorado State University study measured 19 experienced Bikram practitioners during a 90-minute session and found that women burned about 330 calories while men burned about 460. Some practitioners claim to burn 1,000 calories per session, but the research doesn’t support that. Much of what feels like intense exertion in a heated room is your body working to cool itself, not necessarily burning proportionally more energy.
Yoga vs. Other Common Exercises
Yoga generally burns fewer calories per hour than most traditional cardio activities, but the gap narrows significantly with more vigorous styles. A gentle hatha class falls below a moderate-paced walk in calorie expenditure. A vinyasa or power class, on the other hand, lands in the same ballpark as brisk walking at 3.5 to 4 mph.
Mat Pilates burns a similar range: 150 to 250 calories per hour for beginner sessions, climbing to 250 to 400 or more for advanced work. If pure calorie burn is your only metric, running, cycling, and swimming will outpace yoga at every intensity level. But calorie burn during a session is only part of the picture.
The Afterburn Effect From Building Muscle
Yoga’s calorie-burning benefits extend beyond the mat in ways that don’t show up on a fitness tracker. Regular practice builds lean muscle, particularly in your core, legs, and arms. Holding warrior poses, planks, and arm balances is resistance training using your own body weight. One six-week study found that participants in a yoga program gained measurable muscle mass (an average of 2.66 kg) while losing 5.87% body fat. Abdominal strength increased by 11.3 kg, leg strength by 6.0 kg, and arm strength by 4.8 kg.
That muscle gain matters for daily calorie burn. The same study found that participants’ basal metabolic rate increased over the six weeks, and the rate at which their bodies burned fat nearly doubled. At the start, participants burned about 474 fat calories per day at rest. By six weeks, that number had climbed to 985. More muscle means your body uses more energy even when you’re sitting on the couch, so yoga’s real calorie impact accumulates over weeks and months of consistent practice.
What Drives Your Personal Burn Rate
Beyond body weight and yoga style, several other factors shift your calorie expenditure in either direction. Fitness level plays a role: if a pose is challenging for you, your muscles work harder and burn more energy than someone who holds the same pose with ease. As you get stronger and more efficient, the same class burns slightly fewer calories, which is why progressing to harder variations or faster-paced classes keeps the demand high.
How actively you engage also matters. Yoga gives you constant choices about intensity. You can hold a chair pose with your thighs barely bent or sink deep until your quads shake. You can rest in child’s pose during a vinyasa flow or keep moving with the class. Two people in the same room doing the same sequence can have very different calorie burns based on effort alone.
Class duration is the other obvious variable. Most studio classes run 60 to 75 minutes, but Bikram sessions are typically 90 minutes, and some power classes are only 45. A shorter, high-intensity class and a longer, moderate one can end up in the same calorie range. If you’re tracking calories, matching the style and duration to your goals gives you the most control over the outcome.
