This is a lovely posture which stretches spine, hamstrings and hips and shoulders. Once you have warmed up the hamstrings and spine with some half hanuman or forward bends and some supine or seated twists.
From downdog, right foot steps forwards between the hands and knee is directly positioned over the ankle, left fingers spread out and left hand connects with the earth under left shoulder, right leg is strong and straight with quadricep ‘hugging’ up into hamstring.
Inhale: extend from crown of head to back of left heel, lengthening spine
Exhale: hips drop, maintaining engagement of left leg and belly, front ribs and chest gently spiral towards inner right thigh. Neck is long, jaw relaxed. Right arm reaches straight up to the sky, or for more extension, right bicep draws over right ear, palm down, fingertips extend to the front of the room.
Modifications: for tighter hips, drop back knee to earth. For more ease in shoulders, bring right hand to waist as you spiral the chest open to sky.
