Zumba craze

Has anyone jumped on the Zumba bandwagon? As usual, I'm late. My kickboxing instructor convinced me to give it a try. As uncoordinated as I am, I've been doing okay with kickboxing and ballroom/latin dancing with J, so I thought how bad could it be? Plus, a lot of my friends have raved about it. OMG guys, I was a train wreck. Seriously. Flailing arms. Missteps. Confusion. But, I'm locked in for the month. I just hope no one brings a video camera to class.
