Summary

The Musculus rectus abdominis, often referred to as "abs" (short for "abdominal muscles"), sits in front of your stomach and is visible on trained and low body fat people. Its used for bending the torso and lifting the pelvis forward - thus the abs are the main antagonist of the spine stretcher (M. erector spinae). There are tendons that separate the long muscle into packs for better muscle contraction precision.
