The levatores costarum muscles are small muscles located in the back. They are located along the length of the thoracic spine, running from the transverse processes of the vertebrae to the ribs. The levatores costarum muscles are responsible for elevating the ribs during breathing, allowing the lungs to expand and fill with air.

The levatores costarum muscles originate at the transverse processes of the thoracic vertebrae, and insert at the ribs. They are part of a larger group of muscles known as the intrinsic back muscles, which are responsible for maintaining posture and supporting the spine.

In sports, the levatores costarum muscles are important for maintaining proper breathing technique during physical activity. In daily life, they are used in activities such as breathing, coughing, and sneezing.

To work the levatores costarum muscles, exercises such as deep breathing and back extensions can be performed. These exercises involve expanding the ribcage and strengthening the muscles of the back. It is important to consult with a qualified fitness professional to ensure proper form and avoid injury.
