Backward walking and running dates back to the 1970s, when forward-looking runners practised it while injured. Doctors later recommended it as part of physical therapy, and it's often used by baseball pitchers or track runners in preliminary warm-ups.

After a few weeks he promises you will feel less anxious about collisions and can begin to step up your retro running to five or six minutes in total.
