Z Health have a thing about the impact of the visual system on strength - basically if you look up it facilitates extension, while looking down facilitates flexion.  I wrote about it in a post a ways back - The eyes have it...  This idea that eye position corrolates with muscle action: flexion is enhanced by looking down; extension by looking up came to mind when I saw this report /  study:

We make our eye movements earlier or later in order to coordinate with movements of our arms, New York University neuroscientists have found.
