how tall are you? 5'11? a 5'11 90kg shredded dude on a your tiny frame? that is a bad guy and is not going to be easy by any means.
a guy with average genetics is going to need to be in at least the 2 gram range to get to those numbers.
yep, i'm 5'11" and you're right 90 kg RIPPED on my frame (legit 6 inch wrists) would be BIG
i'm @ 75 kg or so right now but i ain't RIPPED, around 8-9% (so i'm nearing fatass territory lol)
my arms are 16 inches now, which ain't too bad for a dude who weighs bout a buck 65
just started doing squats and deads but i gotta be kinda careful with them, coz i don't wanna develop no goddamn godzilla thighs, as my main goal is to keep everything in harmony and PROPORTION
