2. It's nicknamed the tailor's muscle! Its name comes from the Latin word for tailor, referencing the cross-legged sitting position traditionally used by tailors.

3. It's a multitasker! The sartorius helps flex, abduct, and externally rotate your hip while also helping bend your knee.

5. It's part of the pes anserinus! The sartorius joins the gracilis and semitendinosus tendons at the inner knee, forming a structure nicknamed the "goose's foot."
