From Adho Mukha Svanasana, bring your knees down to the ground mat distance. Reach your hips towards your feet and stretch your arms towards your feet, back of the hands on the ground. Extend your sit bones back towards your feet and reach the top of your crown forward, rest your forehead on the ground.
Let the shoulder blades spread and the upper back broaden. For a stronger stretch reach your arms forward, lengthen from the base of your spine to your fingertips, gaze down.
