Raise ‘em till your arms tired, let ‘em know you here
That you struggling, surviving, that you gon’ persevere

from Lupe Fiasco – The Show Goes On Lyrics on Rap Genius

Meaning

Putting your arms in the air is a way of drawing attention to yourself. Let them know that you won’t quit or give up.

These lines are pretty similar to Rocky who was “struggling” but “persevered”.
