An average class will burn 300 calories in one hour. Power Yoga is an active yoga. The main feature of Power yoga is to move quickly between poses to increase heart rate. Because of high intensity most classes typically last 30 to 45 minutes, rather than 60.
It depends on how hard you're working, how much you weigh (and how much lean mass you have). I work near an 80% heart rate for most of my Spinning classes, and I only burn around 400-600 calories in an hour, sometimes less. There are a lot of factors at play. But a good HRM is one of the best ways to estimate how much you really burn in Spinning or in any activity for that matter.
