Literally turn your back on traditional running. Backward running is the way to move forward with experts saying it burns more calories, increases balance, hearing and peripheral vision.

CNN reports that backward walking and running dates back to the 1970s, when runners practiced 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.

"It's a reasonable and a good way to incorporate another means of exercise to lessen the stress on any given part of the body," Barry T. Bates, a professor emeritus of biomechanics at the University of Oregon told CNN.

An American, Timothy "Bud" Badyna dubbed "Backwards Bud" holds the Guinness World Record for quickest backward run on a 200-meter race (32.78 seconds).
