If you were truly into building strength and muscle, you might want to ask yourself: Why aren’t my arms growing anymore? The answer is easy: You need more variety.
However, there are a few principles that need to be defined and understood first in order to really see a major difference, the first of which is the size principle. Forget the biology for a second. What you need to take from this principle is to work big muscles first because they are stronger than the small ones. Think your chest isn’t involved in triceps-focused movements? Think again. Yes, there are variations of the standard bench press that focus more heavily on the triceps, but because your chest typically is stronger than your triceps, you can load up the weight on a close-grip press far more than you can on a rope pressdown and more weight means more gains.
