Revolved Head-of-the-Knee Pose Parivrtta Janu Sirsasana The deeper stretching in this pose gets into the side torso, which opens up the chest and lungs to support the release of mucus and congestion. Bend your right knee and place the sole of your right foot on your inner left thigh. Sidebend to the left, reaching your right arm along your right ear. If you can, hold your left foot with both hands. Do both sides, holding for 10–20 breaths on each side.
