This can be a very prop intensive pose but once you are in it, it is worth it. Begin with right side of body, place the bottom of your right foot against the wall with leg extended. Left leg is bent at a 90 deg. angle and propped up with two blocks and a bolster with maybe a blanket on top. at least two blankets, S-fold blankets, and/or pillows placed along spine for support, lengthwise. Extend your left arm out to the left side and lay it on a smaller stack of blankets either s-fold or triple-fold out to your side. Right arm extends out to the right. This means the left arm is at a higher elevation than right. Head can remain neutral to ceiling or turn to one side. Extra blankets can be placed in spaces that need more support. Neck roll for cervical spine and eye pillow.
Begin with using a double-folded blanket to be placed right above sacrum (see photo), setting it approx. distance 6-8" from wall (adjust in pose). Sit down on the blanket with one hip pressed right up against the wall. As you lower down, swing your legs up the wall. Once in the pose, you can adjust distance to wall, angle of legs to all, blanket and placement of legs all for comfort. Hips and tailbone will be in space between wall and blanket. Arms rest by your side, palms face up or variation with Goddess arms (photo above).
Variations: To ground legs, blanket or sandbag to hang from soles of the feet. Strap can be placed around calves, so you lose the feeling of holding up legs. Tight hamstrings or really uncomfortable with legs directly up the wall? Try a bolster angled into the wall to rest legs on, add blankets for more support or move hips further from wall. Another variation is Legs up on a Chair or on a bolster with blankets on top to bring knees into a 90 degree angle.
