Four months ago, you were 6’0" and 160 or 170 pounds (you said both weights).
Nevermind the height issue (there’s an obvious language issue), but this, above all else, is why you’re seeing slow progress in your arms.
Make the program adjustments already mentioned, but you’ve got to figure out how to eat to support the gains you’re looking for.
