Why are stretches for running and walking important? Working is hard work. We go from our beds to sitting at the breakfast table to sitting in traffic, only to get up and sit some more at work. People all over the United States work hard, and working athletes work even harder. They train after their workday is over or before the work day starts. From a simple athletic perspective, it is important to combat all the chronic sitting with proper stretches to stay loose and prepare for training.
