Zumba is so much fun! I love music and love to dance as well so this is a great way to lose weight and have fun at the same time! :) Good luck!
I've never done Zumba on Xbox. I have gone to Zumba classes and they are fun! It's a great cardio workout and it will make you sweat. I know people who lost weight doing it. If you're wanting to tone your body I would suggest lifting weights on the side. Zumba is good for abs, though. Lots of hip moving. You should do it!
