Rib flare is a common postural variation where the lower ribs protrude outward. While typically a muscular or postural issue rather than a severe medical condition, understanding it can help address associated discomfort and improve body mechanics.
What is Rib Flare?
Rib flare describes a physical appearance where the lower part of the rib cage extends noticeably beyond the natural curve of the spine. This can give the chest a “pushed out” or “flared” look, particularly visible from the front or side. You might notice it more when lifting your arms overhead or lying flat on your back, where a significant space may appear between your lower back and the surface. To self-assess, place your thumbs at the base of your breastbone along your ribs; if your rib angle is greater than 90 degrees, it may indicate a flared position.
Understanding the Root Causes
Various factors contribute to rib flare, often involving imbalances in body alignment and muscular function. Poor posture is a frequent cause, especially when sitting or standing with rounded shoulders or a hunched back, which misaligns the rib cage. Postural deviations like an anterior pelvic tilt or excessive lumbar lordosis can also pull the lower ribs forward and upward. These issues often lead to muscle imbalances, such as weak abdominal muscles unable to support the rib cage, or overactive back extensors and tight chest muscles that exacerbate rib protrusion.
Breathing patterns also play a significant role. Shallow or chest breathing, which overuses accessory muscles instead of the diaphragm, can contribute to rib flare. When the diaphragm is ineffective, the body compensates by pulling the ribs upward and outward during inhalation. Structural variations like scoliosis or pectus deformities can also influence rib positioning, though these are less common primary causes. During pregnancy, the expanding uterus pushes organs upward, causing the rib cage to widen and tip outward to accommodate the growing baby, which can lead to temporary or persistent rib flare.
Addressing Rib Flare Through Corrective Measures
Addressing rib flare often involves a multi-faceted approach focused on improving posture, strengthening specific muscle groups, and retraining breathing patterns. Improving overall posture is a primary step, including consciously aligning the ears over the shoulders and engaging core muscles to support the spine and rib cage. Consistent awareness of how you stand and sit throughout the day can gradually help reposition the ribs.
Targeted exercises are beneficial for correcting muscle imbalances. Core strengthening exercises, such as dead bugs, planks, and pelvic tilts, help engage and strengthen abdominal muscles responsible for pulling the rib cage downward and inward. Diaphragmatic breathing exercises, focusing on expanding the belly rather than the chest during inhalation, are important for retraining proper breathing mechanics and promoting rib mobility. Stretching tight muscles, like the chest muscles and hip flexors, can also alleviate tension contributing to rib flare. Regular practice of these exercises, alongside mindful posture, can help encourage the rib cage to return to a more neutral position.
When to Seek Professional Guidance
While rib flare is often a postural issue, consulting a healthcare professional is advisable in certain circumstances. Red flag symptoms requiring immediate medical evaluation include severe pain that limits breathing, chest pain accompanied by cold sweat, nausea, fainting, or pain radiating to the arm, jaw, neck, or back.
A doctor can accurately assess the underlying cause through a physical examination and medical history review. Consulting a physical therapist or chiropractor can also provide a personalized assessment and tailored treatment plan, especially if self-correction efforts are ineffective or if there is concern about a musculoskeletal imbalance.

Poor posture is a frequent cause, especially when sitting or standing with rounded shoulders or a hunched back, which can misalign the rib cage. Postural deviations like an anterior pelvic tilt or excessive lumbar lordosis can also pull the lower ribs forward and upward. These postural issues often lead to muscle imbalances, such as weak abdominal muscles that are unable to properly support the rib cage and keep it in a neutral position. Conversely, overactive back extensors or tight chest muscles can further exacerbate the outward protrusion of the ribs.
Breathing patterns also play a significant role; shallow or apical (chest) breathing, which overuses accessory breathing muscles rather than fully engaging the diaphragm, can contribute to rib flare. Structural variations can also influence rib positioning; conditions like scoliosis or pectus deformities can affect rib alignment, though these are less common primary causes for general rib flare. Additionally, during pregnancy, the expanding uterus pushes internal organs upward, causing the rib cage to widen and tip outward to accommodate the growing baby, which can lead to temporary or persistent rib flare.

If you experience persistent pain in your back or chest, difficulty breathing, or notice other deformities alongside the rib flare, it warrants medical attention. Symptoms such as severe pain that limits breathing, chest pain accompanied by cold sweat, nausea, or fainting, or pain radiating to the arm, jaw, neck, or back are considered red flags that require immediate medical evaluation.
