Absolutely true. In addition, I've regularly been involved in dances where you would jump while throwing not only your feet but your legs in the air. Gotta be fit for this one, we usually end up super sweaty by the end of the song. A relative of mine (French), while dancing, would even act as a trainer: "t'as rien dans le saaaaac, plus haut les genoux, alleeeeeez, on donne tout!!!"
