Backward walking, also known as retro walking or reverse walking, may add variety and value to an exercise routine when done safely. Turning around not only provides a change of view, but also puts different demands on your body. While taking a brisk walk can have impressive mental and physical benefits, hoofing it for your health may feel repetitive and even boring after a while. Backward walking can be done on or off a treadmill, solo or with a partner. It can serve as a warmup or a mini form of cross-training. Experts say the key is to start off slowly.
