The intercostal muscles connect the ribs and allow the rib cage to expand during breathing. Tight intercostal muscles can limit rib cage movement and breathing ability. Stretching the intercostal muscles regularly promotes healthy breathing which provides several benefits to the body.

1. Intercostal Muscle Stretches
When you breathe in, your lungs expand and the
intercostal muscles, which connect one rib to another,
lengthen. If your intercostals are tight, movement of your
rib cage might be limited, which can affect your ability to
breathe comfortably and efficiently. Stretching your
intercostals regularly promotes healthy respiration, which
benefits your body in several key ways.
