We have a little dancing time on a lot of inside play days, but I also have mats I put on the floor and play musical mats by turning off the music and having them all find a mat (no winners/losers) or we play red light/green light, what time is it Mr. Wolf?, Pop goes the weasel, and other games. Sometimes I play the animal game where I name an animal like a giraffe and get them to walk around stretching, slither on the floor like a snake, stomp like an elephant, you get the idea. In my opinion, that's all fun exercise for the children.
