its exactly what it says. Usually no pose down, no free pose, no free routines...They come in. 1/4, 1/4, 1/4, 1/4, rear DB L calf spike, Front double bi, side chest, side tricep, abs, etc....
Just get there a hour or 2 before the "show" pending the events surrounding it, food, mags, supp companies there?
If you are tryint to get and idea of size and such to see if you wanna compete, you need to go to pre-judging. Thats when they look the best and not to tired. Like you said, its a long day and most of them are on about 20-30g carbs from 2 days ago....
What show?
Have fun.
