Being a "yoga teacher" is tricky business because when your role is to help guide people into a more intimate relationship with their bodies you quickly realize that your own process is one that never ends. In my own practice I am getting back to some basics in terms of alignment and structure. We often forget as we move into a posture trying to replicate what we see the teacher doing to begin with our feet. As a student you tend to watch the posture from the top down but as practitioners we must build the posture FEET FIRST. During your day today and during yoga try to pay special attention to your foot placement. Engage with the earth through the souls of your feet.
As I was playing with my son I noticed some tension in my lower back. I adjusted my posture and began applying force through my feet so that my leg muscles (start with thighs then add calves and hamstrings) were strong and active. I immediately noticed two things happen; my abdominal muscles became active and the tension in my lower back disappeared. Whether walking to the water cooler or chasing a toddler try to do it FEET FIRST and notice the difference.
Walk with gratitude today and be aware of the earth beneath you feet.
