While in the gym about to squat, bench, or deadlift you get your gear set next to the rack making sure that no one else takes it and that the person doing bicep curls realizes its time to get out.
I walked into the gym to post up at the squat rack; the d-bag doing curls realized it was time to jet.

Hanging out. Staying put.

To chill or stand at a spot (like a club or a street corner etc). To claim a spot. The term came from drug dealers on street corners, like light posts and street posts, and there you have it POST UP!
