This is an unsupported sarvangasana. Lie on your back on the floor with your legs stretched out and your palms facing down on the ground by the sides of the legs. Breathe easily and then on an exhale bend the knees and take the legs to the stomach until the thighs are pressing into the stomach. Breathe and raise the hips off the floor on an exhale. Support the hips by bending your elbows so they are flat on the ground with your hands on the back of your hips. Raise the trunk off the ground until it is perpendicular to the ground. Your chest should be pressing into your chin. Exhale and stretch the legs straight up so they are pointing to the ceiling. Keep stretching the body upwards until only your head, shoulders and backs of the upper arms and elbows are resting on the ground and supporting your weight. Then release the arms and stretch them out on the ground so they extend over the head while still resting on the floor. Then finally stretch them towards the legs as if you are reaching for your toes, keeping them tightly by the side of the body. Stay here breathing easily for thirty seconds. Then slowly come out of the pose.
