Don’t do what when running? Don’t keep your eyes closed, or you might crash into a tree or a cactus, etc.
But its okay to keep your eyes closed when using a rowing machine.
Which is what I did again today. At the beginning, I set a timer for 40 minutes and opened my eyes when it beeped. Then, I set the timer for another 7 minutes which took me almost to the finish with eyes closed.
The session was uploaded to YouTube as a screen recording at this link: “Indoor Rowing 71 years old Easier Than Yesterday 03262018”
Happy rowing to you, whether your eyes are open or closed.
