“Sitting on a tucked-under pelvis places constant pressure on the sacrum (the triangular bone at the base of the spine) that can negatively impact the health of the pelvis, pelvic floor (the muscles that fill in the bottom of your pelvis and are, essentially the basement of your entire torso), and spine. Adjusting your pelvis instantly changes the mechanical environment of your sacroiliac (SI) joint, your pelvis, and your lumbar spine.”
For improved sitting posture:
Use a flat-seated chair (like a kitchen chair), or fill in your car’s bucket seat or desk chair with a rolled towel.
Sit close to the edge of a chair. This rolls your pelvis forward, lifting the bone away from the chair.
