Yes that is it. You have to basically induce micro trauma to the fiber. Fancy word for tearing the muscle fibers through the eccentric movement. That is why in my post i brought up the soreness part. Soreness is a really important indicator of growth.
For example, my chest gets sore no matter what i do. And it grows like a weed even with only pushups. Now my arms are a different story, they are really hard to get sore and hence do not want to grow. They pump easily but dont get sore. But when they do, by alternating routines every week they grow at a rate similar to my chest. It's all about micro fractures in the muscle fibers, and not the ammount of weight lifted, sets performed etc..Intensity and variety are key.
You also need to consider that sometimes pumps can get in the way of reaching muscle failure.
I'm the same as you gwl9dta4. My chest grows at a very fast rate as well as my back. In fact some weeks, I skip back training altogether. If I want my arms to grow, I have to train Chest and Back at maintenance.
Hey!! thats exactly why i cant get a good biceps workout,i hit "failure" too early,even if they weight is extremely light,it pisses me off,got any ideas how to reduce pumps?

Well dont reduce pumps. But if you reach failure even with light weights too early then you need to break through the pain barrier. Try this: instead of counting reps decide to keep the muscle under stress for a specified period of time. With a stopwatch set the timer for 60 seconds and keeps repping till the timer runs out. Of the pain becomes extremly difficult then perform rest-pause reps till you get to the time limit. Also try half reps or the classic 21.
