Seated Forward Bend: Stretching the entire back body into deepest submission.
This classical Hatha Yoga posture deeply uncoils the hamstrings and lower back. Paschimottanasana literally translates to "intense stretch of the west," referring to the backside of the body. It soothes the nervous system, stimulates the liver and kidneys, and significantly improves digestion.
Never force the bend by pulling forcefully with the arms. The descent should come from the rotation of the pelvis over the thigh bones. Keep the knees micro-bent if you have tight hamstrings or lower back issues. The key is maintaining a long, uncompressed spine.
