for all i know you guys might be the coolest fuckers in the world, but ur actin like a bunch of bitches...if jubei has 12 inch arms, who gives a fuck...debaser, u keep saying just how small jubei is, yet he sounds the same size as you, if i read correctly...my training partner is 5'11 174 lbs, and has 16.5' arms...he's pretty fuckin ripped with good genetics, so maybe jubei is the same...who knows and besides jubei, who fuckin cares...no one should
For arm mass...stick to heavy compound movements...and at that weight, 16 inch arms are pretty fuckin big...im 204, fairly low bf and i only have 16.5 arms...im not some huge monster, but larger then the average...up the calories, ur arms will never grow without them...im interested to hear what kind of weight you guys with like 18 inch arms are throwin around, to see how far i gota go...im curlin bout 145x5 and close grip bp 225x6-pretty good concentration on tri's...im only 20, so i hope my arms just gota mature a little...i see guys with much bigger arms then me, hittin some pussy weights...good luck to original poster...learn some more bout training tho...im baffled how u have 16 inch arms with that training
