We're always looking for new ways to get moving and to challenge our muscles. Yesterday I saw two women walking up a rather steep San Francisco hill backwards and I thought, "good idea!" An easy way to change things up is by walking backwards (start slow until you get used to the motion). Just like going in reverse on the Elliptical machine, walking backwards forces your leg muscles to work harder and in different ways. And just like reverse lunges, walking backwards puts less stress on the knee joint compared with walking or running forward. Try it out and if you do then remember not to worry what others think about you at the gym.
Fit's Tip: If you are going to try walking backwards then do it someplace safe and free of obstacles like the treadmill or a track.
