Welcome to the forum.
On a side note, I want make a comment reference your arm thread.
IMO, you construct a solid full-body routine, a solid diet, add a little "good weight", and the arms will follow.
Personally, I believe that if one builds the larger muscles of the body, the arms (which are the facilitators of moving these larger muscles), will have no choice to get stronger/larger to balance out the need of the larger and stronger muscle being worked or used.
The arms are the "gas" that provides the fuel of moving the larger muscles, and gets the larger muscles' "engine" revved up..........
Think about it young man. Bench Press (pecs, shoulders, etc) you are moving the arms. Variant of rows (back), you are moving the arms. Military Press (shoulders), you are moving the arms. The arms open the door to the larger muscle groups.......Okay, we get the idea...
Include direct arm work in your routine, but construct a full-body routine along with a sound diet, and you will take many steps forward getting the body you desire.
Give your body "a reason" to have stronger and bigger arms. And, this ISNT through curls, and blasting your arms with an ungodly amount of sets and reps. It is through getting the larger muscle groups involved, and this only comes through the use of the facilitators: The arms.
What I do and briefly how I approach thought on the arms:
Even though I know body weight (and working the larger major muscle groups) are the major components in obtaining larger arms, I have always intensely worked my arms (bi's and tri's), as I did any other muscle group.
I view the arms as the weakest link in the chain (but also the facilitators of) the larger and stronger muscle groups (chest, back, etc), and keeping them strong through working the larger muscle groups----and arms directly, has served me rather well.
IMO, the arms fatigue first in "most" back development exercises, say for example, performing the T-Bar-Row. Which means the back muscle targeted isn't really getting fully exhausted like it should,
because the little bicep "can" fatigue first before the back muscle. Therefore, "properly constructing" some direct bicep work away from (lat pull downs, various rows, etc), "can be" important, in that it can build up other strength, and just provide the extra rep (or two) in bringing the back closer to optimal fatigue. Both the back and the Bi's are involved in most pulling movements, and its just logical that the bi is going to get stronger as you work the larger muscle groups (example back) to maintain "effective" balance.
Most think pounding the arms with exercises is the key to effectively increasing arm size--this is not the case; using the arms to build the larger and stronger muscle groups (such as chest, back, and overall body such as such as in the dead lift, and legs such as the squat), and gaining "proper weight" is the key to larger and thicker arms. Not pounding the arms with an "ungodly" amount of sets and reps.
