A boat-shaped abdomen is another term for a scaphoid abdomen - a condition in which the abdomen's anterior wall is sunken and hollow.
The abdominal muscles called rectus abdominis are the ones that work hard to enable you to flex your abdomen when doing sit-ups. Other muscles used while doing sit-ups are the external oblique's, tensor fasciae latae and rectus femora's.
The abdomen is distal to the chest. The chest is located superiorly to the abdomen in anatomical position.
The diaphragm is the muscle separating the abdomen from the chest
The diaphragm contracts and so your abdomen comes out during inspiration.
