yeah it does, but according to Mr. N then i'll be even more out of proportion ie. torso>arms
i think the weighted chins will be the answer, but we'll see
No worries for that, that would only happen when you just started training. The longer you train, the slower your progress. BTW, I don't believe that hypertrophy occurs 100% locally; there's always tention/stimulation of other muscle groups.
Regarding weighted chins, most folks aren't able to perform chins with a full ROM and a slow negative (I'm not an exception on this
) , but there's nothing wrong with some extra weight in case you're an exception to this.
