Let's keep learning about the muscles in the human body!
Last time we learned about the latissimus dorsi
Next up is the rectus abdominis.
These are the muscles in the front of your stomach, also called your abs or abdominal muscles.
You use them when you do bend forward, like you're doing a sit up.
(from: wikipedia - rectus abdominis muscle)
Since these muscles sometimes look like six bumps on your stomach,
some people call them a six pack.
