u could always try doing the negatives slower than the positives on each exercise,if you dont do this already. for size heavy sets and try lowering the amount of reps u do,
i personallly struggle with my arms abit. ive got 18inch arms but ****asll on the triceps,ive got it all on the biceps, i just cannot seem to pack size on them,
ive done dips with 100kg weight on my lap,still no joy.
what i would say is focus on both the tricep and bicep,and train them as intense as each other,or youll end up like me
