Your pelvic floor is a series of muscles that span the
area under your pelvis, wrapping around the underside of your bladder, uterus and rectum.
Slight Inversion: This is a form of Supported Setu Bandha Sarvangasana (Supported Bridge Pose), with a bolster or
pillow under the pelvis instead of a block.
Slide onto the bolster
crosswise under your pelvis and release down onto it, making sure the entire bolster is below your waist and is not supporting the curve of your lower back.
Bend your knees, press your feet into the wall and lift your pelvis off the support a few inches, tuck the support a little higher
up under your pelvis, then lower your pelvis onto the support again.
Position a
block under your pelvis, lower your sacrum onto the block, and drop your knees out to the sides again, pressing your soles back together.
I recommend women try placing a pillow or two
under their pelvis and having their partner keep their torso more upright.
If you have a bolster, you can keep it near your bed and just slip
it under your pelvis whenever you like, either at the beginning of the night or in the middle of the night.
