Some level of direct arm training is mandatory regardless of goals, How much depends on what your ultimate objective is.
Same vein as the last one, ab and oblique work is mandatory for everyone.
Specificity is highly overrated.
Crossfit isn’t stupid.
What bodypart isn’t mandatory?
Calves.
Your Mastication muscles.
No, but most people who do cross fit are
At least uneducated.
I 2nd Calves and add forearms.
Forearms get their work from picking up heavy things. I don’t think I need to do burnouts with the bar on wrist curls.
I agree, but I think forearms are definitely a body part that all naturals need to achieve a strong look to them. I personally am trying purposely to get my forearms bigger than my upper arm. My dads upper arms are 15 and his forearms are 16 now I believe and he looks jacked in a tshirt
I think my days working for my dad doing landscape work helped develop my forearms. I spent a lot of time running a shovel and laying sod. If the sod was good and it was the smaller rectangles (3’x5’ I think) then I could just grab a fistful of grass and carry a piece in each hand.
Definitely agree. I added most of my mass doing job hand work for a plumber in my teens. I’ve always had decent forearms because of just working, so I’m trying to up it now and make them hugeee
I had a dyslexic moment and read that as above…
You’re not the only one
None of them, they are all mandatory.
Im not asking where the hell your mind is…soooo wrong 
Id expect that from @ChickenLittle 
I’ve cursed out the bar, but never myself. Might wanna look into that one lol
I’ve been reading her log, it’s tainted my young mind.
@MarkKO And @dchris I actually wrote that wrong and meant hand job work. Those were dark times laying pipe.
I see what you did there

I swear ,HATE does not even come close to describe my feeling regarding the concept that people do this…
Not flaming, just asking (if I may)…Why such antipathy? This is literally lifesaving surgery for some individuals.
