Step by step
From Mountain pose. For new students attempt this pose near a wall for the first time to help with balance.
Gaze at a point at eye level, to help you to keep your balance.
Shift your weight onto your left leg. Ground through the four corners of your left foot. Engage the quadricep muscles in the front of your left thigh to stabilize your knee.
Bend your right knee straight in front of you until just the toes touch the floor. From the hip joint, externally rotate your leg out the right.
If you feel steady here, lift the right foot to your left inner ankle, calf muscle, or left inner thigh.
Keep your core muscles engaged.
Firm your left hip in, lengthen your spine, soften your shoulders and keep your chin parallel to the floor.
You can keep your hands on your hips, lift them to prayer in front of your heart, or you can lift your arms up to the ceiling. Hands can remain shoulder-width apart.
Stay in the pose for at least 5 breaths.
Lower your leg and arms down, stand in Mountain Pose.
Repeat on the other side.
