Each week the coach finds something else that I need to work on. This week I needed to focus on my arms during the backstroke. So I focused completely on my arms to the extent my legs dragged behind me slowing me down. I wasn't aware of this.
The coach stopped me, not to tell me I was doing better, which was what I was hoping for. However, he told me I needed to kick more. I explained that I was focused on my arms and, in the words of my brother, I'm the kind of person who can't chew gum while walking.
I now realize why I stink at swimming and most sports.
