Abdominal Muscles (Abs)
The abdominal muscles form the front wall of the belly. They bend and twist the trunk, support the spine and protect the internal organs — the "six-pack" is one of them.
What it is
The abdominals are several layered muscles, including the rectus abdominis (the "six-pack"), the obliques at the sides, and the deep transversus abdominis.
Where it is
The front and sides of the abdomen, between the ribs and the pelvis.
What it does
Bend the trunk forwards, twist and side-bend it, and tense to support the spine and increase pressure (as in coughing or lifting).
Everyday use
Sitting up, twisting to reach behind you, coughing and lifting all rely on the abdominal muscles.
When things go wrong
Common problems affecting the abdominal muscles (abs)
- Abdominal muscle strain
- Diastasis recti (separation of the six-pack muscles, common after pregnancy)
- Hernias through weak spots
Education and reference only. This explains the anatomy in plain terms and is not a diagnosis. Sudden severe symptoms — such as crushing chest pain or collapse — are an emergency; call 999.
Looking after it
Keeping it healthy
A strong, balanced core supports the back; gradual strengthening and good lifting technique help prevent strain and back pain.
Did you know?
An interesting fact
Whether you can see a "six-pack" depends mostly on body-fat level — the muscle is there in everyone, just often hidden.
Answers
Abdominal Muscles (Abs): frequently asked questions
What do the abdominal muscles do?
They bend and twist the trunk, support the spine, and protect and compress the abdominal organs (helping with coughing, lifting and breathing out forcefully).
What is diastasis recti?
It is a separation of the two halves of the "six-pack" muscle, common in and after pregnancy. It often improves with time and specific exercises; a physiotherapist can advise.
