If you weigh more, you burn more, a person doing the same class but having say, my weight burns ALOT more than someone who is much smaller ie with 10 - 15 kilos to burn, particularly if you push yourself (and don't you just want to/feel like you can so much more with Zumba? I am constantly amazed and I know I do push hard and how quickly my body takes up the challenge? How quickly it's changed - I've done Zumba 45 mins most days (I mean at least 6 of 7 days a week) now since mid January, and how much my body shape is changing is constantly amazing me - and the scales too have budged a bit. I also usually work out with weights strapped to my wrists, only recently did I stop having them strapped to my ankles too.
You have to watch yourself though - at some point you're wonderful body is going to get used to it and you have to find other ways to push it - hence the weights for me.
If Zumba wasn't so awesome, I don't think I'd have managed to stay quite so committed :)
