Head to knee pose is a great way to strengthen and elongate the hamstrings. Once, you've mastered warrior one and Two where you have a bend in the knee then we're going to work on fuller extension with the head to knee pose. Again, assume that warrior one position with the back foot facing towards the front of the room. Opposite foot, away from the mid line of the body. We're going to face it and come up in that warrior one position, opening up the back hip and leaving the shoulders square. And, come out with our hands to the side and around to the back. And, as you bend from the hip, navel to spine, release down leave a slight bend in the front knee. Big inhale. And, if you want to just reach your finger tips fine. If you can flatten, exhale and pull your hips up towards the ceiling thigh up towards the chest. Big inhale, release. And, don't bring the knee in front of the toe on that release exhale. Round through, try to keep a nice flat back. Now, once you reach an extended pose I want you to try to hold for ten to twenty seconds with breath. If you need to release and come back. Maintain integrity. Pull that navel up to the spine. Release your hips up towards the ceiling. Slight bend in both knees. And, release forward before you come up into neutral. Take a big breath up. Inhale and release. Beginners, really watch hyper extending the knee joint in the front and the back on that pose. And, advanced once you get down towards the bottom. If you're able to hold it for ten to twenty seconds. You'll get used to the blood rushing to the head. You'll be able to control that with your breath, when you get more advanced with it. But, try to focus on form first and relaxation in the knee joint for that head to knee pose.
