After ten breaths in shoulder stand posture, lower your legs over your head for Halasana, plow pose. Lift your sitting bones, stay active through your legs and rest your toenails on the mat pointing your feet if possible. If your feet touch the mat you can release your hands from your low back and interlace your fingers reaching your knuckles to the front of your mat. If not, no worries just try and keep your legs straight and let gravity assist you. As in the previous posture, your weight is in your upper arms and shoulders, not your neck. Engage all three Bandhas and breathe for 8 breaths. This pose opens your shoulders and hamstrings and strengthens your abdominals while improving your circulation.
