Lunch bunch

I do the yoga sometimes at the Y, once in a while when there is no other class. And I do the "lunch bunch," I don't why they call it that. I think it's because people come during their lunch break. First we do stretching, then we walk around the track. Then running and running and running. And then there is weights. Then we lie down on the mats and we do the stretching and that the end of the hour.
