abs

Illustration of the human abdominal muscle structure. The image shows the rectus abdominis, commonly known as the six-pack, with its individual muscle bellies clearly defined. The external obliques are visible on either side, layered beneath, and the tendons that intersect the rectus abdominis, creating the segmented appearance. At the bottom, part of the lower ab muscles and connective tissues are rendered in grey with slight muscular details. The illustration uses shades of red and grey to differentiate muscle groups and structural elements.
