Utilize your centers while walking. Try the following exercise: Hands on your shoulders, elbows out. Inhale, step forwards onto your right foot, exhale and twist your upper body to the right. The left elbow will be facing forwards. Repeat on the left leg. Repeat 4 times on each side. Keep your shoulders down and do not lift your chest up or arch (hyper-extend) your back. Try this traveling backwards slowly: Step back onto your left leg, turn your body toward the right leg (front leg) so that the left elbow faces in the direction of the right leg (opposition). Repeat stepping onto the right leg. Try to feel your oblique abdominal muscles working. Repeat 4 times on each side.
