I've also taken lots of dance classes over the years (flamenco, middle eastern, hip hop, Tahitian), so I know what coming out of dance class feels like and how my body feels the next day. I was shaking so much at both ends in that class yesterday that I thought a couple of times I was going to fall. I'm not sure what exactly happened afterwards, but I was so chilled and shivering that I put on a big sweater and my space heater at my desk; maybe I was a little in shock (?). This is WAY more hardcore than any mamby-pamby dance class. All I can say is those women in that class have the arms I've always wanted and have never had. 42 years old seems like a good time to finally attain them.
