We can move the spine from side to side or laterally. When we move the spine towards the right we are opening the left side body and when we move the spine to the left we are opening the right side body. This opens the side ribs and allows the lungs a greater capacity to expand sideways.
Moving Laterally with the Breath -
Pairing the Breath with Lateral Spinal Movement
Try this movement again, this time lifting the left arm and expanding the left side body. You can take several breaths on each side or simply move with each inhale and each exhale, feeling how the movement and the breath work together in a yogic flow.
