Zumba on Wii

Ok, had a scout in the search but could really find what I was looking for sooo... for the ladies, and maybe gentleman who do Zumba on the wii, whats the best thing to log it under or how many calories burned? any ideas would be good. I generally only eat half my cals back if i do any exercise above my normal activity.. Im doing 20 minutes on beginner as Ive just started, although i felt really energized and could of done another 20 but my daughters nabbed it off me! good sign I think x
