Revolved Side Angle Pose: Step-by-Step Instructions
Stand in Tadasana. With an exhalation, step or lightly jump your feet 3½ to 4 feet apart. Rest your hands on your hips. Turn your right foot out to the right 90 degrees and turn your left foot in slightly to the right. Align the right heel with the left heel. Firm your thighs and turn your right thigh outward, so that the center of the kneecap is in line with the center of the right ankle.

Exhale and turn your torso to the right until youre facing directly out over the right leg; as you do this, lift your left heel off the floor and spin on the ball of the foot until the inner left foot is parallel to the inner right foot. Then exhale again and bend your right knee. If possible, bring the right thigh parallel to the floor. Keep your left leg active by pressing the thigh up toward the ceiling and extending strongly through the left heel. At the same time, resist the lift of the left thigh by pressing the tailbone toward the pubis.
