These would be the abdominal muscles.
There are the abdominal muscles and the oblique's. They help to keep you standing straight and when working properly, your back healthy.
The abdominal muscles do many things like hold and potect the abdominal cavity and assist in breathing. But, the most obvious one is posture. They are the antagonists to the muscles along the spine and help maintain spinal curvature. The action is known as flexion of the spinal column.
A large group of muscles in the front of the abdomen that assists in the regular breathing movement and supports the muscles of the spine while lifting and keeping abdominal organs such as the intestines in place. Abdominal muscles play a key role in exercises such as "sit-ups." They are informally called the "abs".
Sit-ups help work out your abdominal muscles.

Help in breathing and separation of thoracic and abdominal cavities .
This is due to the musculature of males in comparison with females.diaphragmatic/abdominal breathing involves the deep descent of the diaphragm to increase intrathoracic volume for air to be sucked intn lungs.this facilitates better oxygen intake and utilitization by the body.Tight dress patterns of females is also a contributing factor as the abdominal muscles cannot contract effectively hence a switch to thoracic breathing.
Protein is important in building muscles and is needed for any muscle-building regimen. Aside from that, an abs workout is needed to define and shape the abdominal muscles.
Intercostal muscles are several groups of muscles that run between the ribs, and help form and move the chestwall. The intercostal muscles are mainly involved in the mechanical aspect of breathing. These muscles help expand and shrink the size of the chest cavity to facilitate breathing.
Some floor exercises, if done correctly, do strengthen abdominal muscles. Crunches and situps do this. Some yoga or pilates positions accomplish this as well.
