How to have correct posture?

Anonymous
I've watched some vids and read about it, but they don't really teach properly imo.. I don't get get it; should I push my chest out, or pull my shoulders back? That's tiresome as hell, and doesn't seem natural. And walking completely straight with my back seems to put stress on / hurt my lower back.

Anyone knows how good posture should feel?

:-D Thanks
