I like this topic. Nice post bro.
We are all different and we all have individualistic genetic predispositions. That is what makes our sport special. It is the epitome of an "individual sport." I think that a bodybuilder should look at his physique as a sculpture. The way Michelangelo would look at the physical proportions of "David" when it was almost complete, and decide which areas needed further attention.
A balanced physique will always be superior to a "mass monster" in my opinion. And I think it is this balance that should be the ULTIMATE goal for all of us serious competitive bodybuilders.
For me..., my entire upper body has always been "easy" for me. But it came in steps. When I was 15-16 I had great arms and delts, because my main goal was to look great in a tank top, so I put a HUGE focus on bis, tris, and delts. It worked..., but I ended up looking like an ape of some sort because I had NO CHEST and NO BACK. lol Ahhhh, to be young and stupid, right?
So after a few years of determination, my Chest was/is now one of my best bodyparts, by far. My back still gives me trouble. I have issues getting the density I think that I need for balance.
My most "pain in the ass" body part has always been my legs. Again.., after 18 months of determination, my quads are one of my best body parts now. However..., I have really long Achilles tendons, so extreme mass on my calves is a gentic impossibility. I do have good shape to them, but they will NEVER be "huge calves" because my genetic structure will not allow it.
Bodybuilding is a continual evolutionary process bros. Give yourself an honest assessment once per year and set new goals for the next with regards to which bodyparts you think need improvement. Eventually, you will achieve a balanced physique. It only took me about 14 years.
