My personal recommendation would be a pre-exhaust routine.
Do barbell curls until the bar literally falls out of your hands then
immediately, with the least amount of rest between sets, then do
a set of supinated chin-ups or pulldowns or pulldowns, again, like
barbell curls, go to failure with full reps in good form then partial
reps for as many possible until you are unable you are unable to
grip the bar.
With minimum rest between exercises . . .
For triceps, I would do lying cambered bar triceps extensions to
failure, then as many partials as possible, and with the bar still in
your do as many reps as possible of presses to you neck then run,
don't walk, to the dip station and do as many reps as possible,
and as many partials to failure until to almost you almost fall off
the machine.
Reps; 8 - 12. And when you reach your 'guide' number do not
stop, go to failure on each set. And when you reach the guide
number on the number of sets for three consecutive workouts
only then add weight where appropriate.
Do one cycle, maybe two, never more than three. If you can
do more than three set / cycles, you are not working hard
enough. When you are finished you should feel like you have
climbed a tall mountain with a refrigerator tied to your back.
Spend of movement should be controlled. You should be able
to stop the weight at any position, positive of negative. That
means you are controlling the weight and the weight is not
controlling you.
Do this three days a week with zero arm work in-between.
No presses or pulling. Ideally this should be a part of a full
body workout. But I get that it is not always possible but
do not touch your arms between workouts. It will only
hinder your progress. Do the minimum possible for the
remainder of your body, focus on squats.
I did this years ago and my arms were never bigger.
