Let's keep learning about the muscles in the human body!
Last time we learned about the trapezius
Next up is the latissimus dorsi.
These muscles are sometimes just called lats.
You use your lats when you pull your arms down from the sky like doing a chinup,
when you pull your arms toward your body like opening a door,
and when you pull your arms up from the ground like picking something up.
