How many calories will I burn in a single class?

That’s hard to know with any certainty. The estimates range from 350 to 650 calories per class. It really depends on too many factors to make any kind of blanket prediction. I let somebody bring a body monitoring device into a class and it showed that he burned 748 calories — clearly he was working hard. The key is to think of calorie burning as simply one small benefit of practicing yoga. There are far more benefits than that.
