OOF...

lots of reps.
Take 30-40% of your one rep max for curl and tricep extension. Start off with 12 sets of 12 reps, with only 10-30 seconds of rest in between. Every week add either another set or another rep. So week 2 you'd do 13 sets of 12 reps. The week after 13X13. If it gets too easy, increase the weight by a little, or decrease rest time.

bicep curls for biceps
weighted dips for triceps
farmer walks for forearms
weighted pull-ups with shoulders width grip

Trying this; will report results later.

more arm volume more often
