You've got another difficult arms workout in Arnold's 1-10 method today, in addition to shoulders, forearms, and abs. At the end, your biceps should feel like they're about to bust out of your skin. This is a good thing! Maybe it makes you think of Arnold's famous monologue about the pump from the movie "Pumping Iron," but what he said in the book of the same name is just as memorable. He said:
"Bodybuilding should be fun because you get to feeling of satisfaction which is very hard to explain. A bodybuilder knows that when he pumps of his muscle it means growth. The muscles grow. So therefore he knows when he pumps up well, that is progress. And that satisfies him because he feels the progress in his body. Therefore the pump feels good. It's actually the best feeling a bodybuilder can have. It's difficult thing to explain. Sometimes we joke around and we get a good pump and we say you have to admit that a good pump is better than coming. Somebody off the street wouldn't understand that, but sometimes a pump is the best feeling you can have."
You're not just somebody off the street. You get it. Now go get it.
