Kettlercise calories?

Does anyone have any idea how I would log kettlercise calories burnt?

Thanks

It claims about 600 calories, but for a 37 minute workout probably not. Of course it depends on how big you are and how much effort you put into it. Kettlebells have a reputation for pushing your heart up pretty much straight away and keeping the max effort for the entire workout. Probably somewhere between 400 and 500 calories.
