Walking meditation.
Find a space outside, and simply walk at a slow or medium pace, focusing on your feet. Try to distinguish when your toe touches down the ground, when your foot is flat on the ground and when your toe points back upward. Feel the roll of your foot. Observe sensory details: a tingle here, a pull of the sock there.
When your mind wanders, and it will, gently bring your attention back to your feet. You’re building a skill of noticing when your attention drifts into default mode and bringing it back into focus. This ability can help you be more present and in control of your attention every day, especially in times of stress.
Plus, Kerr points out, this practice is a mild form of exercise. Start by dedicating a specific time and place to practice, and when you become comfortable with walking meditation, try it as you walk to the bus stop, office or just about anywhere.
