Musculature of abdomen
Musculi abdominis · Svalstvo břicha
Muscles
Looks like
The group of belly muscles: rectus abdominis in front, the external and internal obliques and transversus abdominis at the sides, and quadratus lumborum at the back.
What it does
Support the trunk and spine, move and twist the body, and raise belly pressure for breathing out, coughing and straining.
Keeping it well
Train with varied core work, not just sit-ups; a bulge on straining or a gap at the midline after pregnancy can be assessed by a doctor or physio.
