The abdominal strap, also called "wall" or "corset" or "sheath", represents the most important musculature of the body in terms of surface area and functions. It is made up of 5 paired muscles that cover the entire abdomen. The whole abdominal strap protects your "belly".
The first “vital” dynamic activity of the abdominal muscles is to create the pressures in the abdomino-pelvic enclosure, to manage them and to direct them according to the action in progress.
