Bananasana

Bananasana is a wonderfully even side body stretch.

In banana we get to use the prop to keep the pose from sliding. The bolster acts like a door stopper that helps prevent the legs from rolling out of the pose when relaxing.  Without the bolsters, it would use more muscular energy to hold the pose than you want in a yin posture. Some people's shoulders might be bothered with the arms straight, try folding the arms or using a blanket or bolster under the forearms.
