Add It Up

This high-energy, groovy combination comes with some challenging arm movements. The first two eights follow the singer's words, so the timing is tricky. Start sassy and casual, as if you're talking to your coolest best friend. Then let it explode on the bass.

Plant your feet with soft knees, throw with real aggression and let your hair fly. The last stretch is a party with your friends. Don't get so carried away that you forget the ending.
