From Virabhadrasana I, place your hands on your hips, inhale, lean forward and step your left leg forward a little.
Exhale, hinge forward from the hip joint, lift your left leg parallel to the ground behind you, hips level to the ground. Roll the inner thigh of your left leg up, flex your foot and press out through the heel.
Reach your arms back or reach your arms forward in line with your ears. Lengthen through your spine and the sides of the body, gaze to the ground or to your fingertips if your arms are forward.
