I'm hearing alot about working the core muscles. When i ask my coach to define them, she vaguely motions to her hips and stomach.
What are the core body muscles?
Why are they getting so much attention, recently?

:cane::bed:Just curious, but are these "core muscles" fast twitch or slow twitch? Or both? If both, just how much: 50/50, 60/40, 75/25 or depends on age? In my case, I'm probably 100% slow twitch?
