I do Zumba on the Wii, Just Dance, Country Dance and yoga in my living room. I don't usually feel silly. But, I had several years of dance, flags, poms in both high school and college and even took ballet as one of my college gym electives. The only one that sometimes makes me feel odd is yoga. Some of those contortions feel weird, look strange or my body just doesn't want to go there. Still. Also, I won't do any of them if my teens have friends over. It may not feel silly for the most part; but I definitely prefer to not have an audience. My performance & recital days are behind me and will most likely remain there.
