They either pump out a bunch of reps to get their blood moving or they drink a N02 or Nitric Oxide Workout drink that promotes "MUscular Vascularity" which causes every muscle in your body to expand and get bigger temporarily while you work out.

I know I take NO Xplode and PLasmavol before I workout and I'm around 135lbs and it makes me look like I'm around 145lbs by the end of my workout.

I hope that helps explain it.
