wow this is exactly what i was trying to get across -
"In fact, it’s pretty easy to distinguish between a “pumper” and a heavy lifter, even among pro bodybuilders.
The pumper seems to double in volume midway through his workout. When you look at him in an un-pumped state, he won’t appear that impressive. Give him twenty minutes in the gym and you’ll think he’s a completely different person. An hour after his workout, he’ll once again look less than impressive.
On the other hand, find a guy who does a lot of heavy lifting and you’ll see someone who doesn’t change that much regardless of if he’s pumped or not. He’ll look just as solid, massive, and impressive at rest than during an intense workout.
In the bodybuilding world, you can compare the physiques of Flex Wheeler and Francis Benfatto, who were noted “pumpers,” to guys like Dorian Yates, Johnny Jackson, or Branch Warren who are known for lifting in the lower rep ranges. Granted, Flex and Francis have more aesthetic physiques, but I’m only talking about muscle density and that rock-solid look."
