I recently asked a lot of my students and even many trainers and instructors what are your muscles? When someone tells you to contract your core, what do you do?

QUESTION:
What do you do when you are asked to contract your spine? How do you lift your pelvic floor muscles?
Definition: All the muscles that support the spine. (Thanks to one of my first teachers, Mo Chiodini)
