Burning Calories

A standard yoga class can burn anywhere from 180–460 calories, depending on the intensity and duration of the class and how much you weigh.

Colorado State University researchers found hot yoga practitioners were at the top of that range: Women burnt around 330 calories during a 90-minute class, while men burnt around 460 calories (due to being generally larger in size).

You sweat a lot more in a hot studio, which means your body must work harder to regulate your temperature and your heart must circulate more blood. That means burning more calories than you would in a traditional yoga class without heat.
