Notice when you walk where the motion of your legs originates. The power should come from your hips. This week, when you are walking try to focus on the motion coming from your hips and your legs just lightly swinging back and forth on a pendulum.
While this isn’t exactly what is going on, it helps me to imagine a scooped shovel in the butt (the back of my hip) that swivels on each side and pushes my legs forward. It’s almost as if a little hammer connected to a c-shaped scoop gently knocks the top of my leg causing the whole leg to swing forward.
Try it and see how it feels. See if you need to drastically alter how you walk in order to do this exercise.
