Setu Bandha Sarvangasana - Supported Bridge Pose
This is a back bend that you learn in stages. First thing to try is
simply lie on your back, bend knees so feet are flat on the floor.
Gently lift your hips up and hold. Repeat this enough times until
until you are feeling strong. Start placing foam blocks under your
hips to rest on. It might be 1, 2, or 3 blocks. When you can get
to 4 foam blocks, try using a wood block eventually getting it under
you in an upright position. Then you can start working on extending
your leg. Do not rush. this can be a very challenging pose. Below
is another one of Geeta's great teaching videos.
