Sartorius

Looks like

The longest muscle of the body, a thin strap crossing the front of the thigh from the hip bone to the inner knee.

What it does

Helps bend, open and turn the hip and bend the knee — the cross-legged tailor's pose.

Keeping it well

Rarely a source of trouble on its own; its tendon at the inner knee can be sore in runners.
