Three-Minute Thoracic Stretch to Undo Desk Posture, Urges Osteopath
An associate osteopath says prolonged sitting mainly harms the hips and mid-thoracic spine, leading to a kyphotic posture. He advocates a daily, three-minute thoracic-rotation routine, focusing on the Open the Book stretch (with Thread the Needle as a backup), to improve thoracic extension and rotation and counteract desk-bound stiffness.
