Struggling to take a satisfying, deep breath while sitting at a computer is a mechanical restriction driven by pelvic anatomy.
Structural therapists focus on the psoas major, a thick muscle that connects the lower spine to the top of the femur. The upper fibers of the psoas physically intersect and weave into the diaphragm, the primary respiratory muscle.
Sitting in a chair for eight hours keeps the hips flexed, causing the psoas to shrink and harden. When you attempt to stand or sit upright, the shortened psoas acts as a tether. It pulls the diaphragm downward, physically locking the ribcage and preventing the lungs from expanding to their full biological capacity. Releasing the hip muscle provides immediate slack to the respiratory system.
