The oblique muscles play a key role in stabilizing the rib cage by connecting the ribs to the pelvis and abdominal fascia. When they function well, they help keep the rib cage stacked over the pelvis, preventing the lower ribs from flaring outward.
This alignment allows the diaphragm to work efficiently for breathing while creating intra-abdominal pressure that supports spinal stability.
When the obliques don’t effectively control the rib cage, the body often compensates with excessive spinal extension, rib flare, or overuse of the lower back muscles to create stability. Over time, these compensations can reduce efficient force transfer through the trunk and contribute to altered posture, inefficient movement, and increased stress on the spine during activities like walking, lifting, and rotating.
