Rib Flare

Rib flare describes a posture where the lower ribs angle forward and stick out.
It often appears when the spine and pelvis fall out of alignment.
You might notice a gap under your ribs when lying on your back or a forward chest posture when standing.

Common causes

• Weak deep core or oblique muscles
• Tight back extensors
• Habitual arching of the lower back
• Shallow breathing patterns

Rib flare isn’t dangerous but can affect breathing, balance, and appearance.
Strengthening the core and improving breathing mechanics helps the ribs settle into a neutral position.
