I tried it at the beginning of my journey, but I did not see results, no. After working with my trainer and doing some testing at my gym, it turned out that Zumba accelerated my heart rate into too high of a zone for too long... so I was not burning stored fats. I slowed things down and started doing interval training and that did the trick for me.
I loooove Zumba. The only thing I saw though was better endurance. I don't think I did it long enough to have a difference. I tend to get bored with things so now I have Zumba and Beachbody and I also have one of Jillian Michaels workouts but it is a little bit much and she is annoying in this one
