We've been doing Adventure to Fitness, which the kids LOVE (and so do I!). You can find out about it here.
We went on the castle adventure and now we're in the middle of the dinosaur one. Our recess isn't quite long enough to do the whole thing, so it's been kind of nice to just do it in little pieces, even as just a warmup in the morning when they come to school sleepy.
Anyway, during sharing time one morning, I told the kids that I frequently go to Zumba class. The kids found this very amusing and one of them said that he goes to Zumba with his mom at church. I was chatting with my Zumba instructor after class and she actually volunteered to come and teach my kids for half an hour. You wouldn't believe (or maybe you would) how ridiculously cute it was to watch 24 kids try to dance to Starships by Nicki Minaj.
My favorite part, though, was when she asked them to freestyle in the middle of the circle. The kids really wanted to hear "Opa Gagnam Style", so she played it and every kid (and one mom!) spent the next five minutes bouncing up and down, Gagnam style. Naturally, I caught it on video. It was incredibly cute!
I wish I could post it here, but since I can't, here's a cute video of some babies doing it too.
