once i went to a high intensity push/pull 3 day a week program my arms finally grew again . each day focus on 2 big exercises(compound) , more or less focussed primarily on the big 3 lifts (squat , bench , deadlifts)and each training day give that big 1st lift your most on heavy low reps around 3 to 4 each set . keep heavy working sets to no more than 3 to 4 on the 1st lift & 2 for the other 2 lifts or so . heres a example :
day 1 : legs&abs
barbell squat (3 warm ups progressively heavier) 4 work sets heavy
stiff leg deadlifts (2 warm up sets prog. heavier) 3 work sets heavy
leg press (1 feel set) 2 working sets moderate reps
good mornings (1 warm up) 1 work sets heavy
seated and standing calf raises 2 work sets each
finish day with ab work
(NEXT DAY OFF)
day 2 : chest , delts , tric.
barbell bench pr.(3 prog. heavier warm ups) 3 work sets heavy
incline dumb. bench pr.(1 feel set) 2 work sets heavy
dumbell delt pr.(1 warm up) 2 work sets heavy
close grip bench pr.(1 feel set) 2 work sets heavy
1-arm dumb. side lateral raise (1 feel set) 2 work sets heavy
body wieght dips 1 set heavy
(NEXT DAY OFF)
day 3 : back , traps , biceps,wrist
deadlifts (4 prog. heavier warm ups) 3 work sets heavy
barbell rows (2 warm ups) 3 work sets heavy
barbell shrugs (1 warm up) 2 work sets heavy
close grip pull ups (1 feel set and a bic. warm up) 2 work sets heavy
alt. dumbell curls (1 warm up) 2 work sets heavy
bar reverse grip curls(1 warm up) 2 work sets heavy
1-arm dumbell wrist curls(2 warm ups) 2 work sets heavy
note : each week i personally alternate my stiff and regular deadlifts in and out of my rutien so everyweek im only doing one or the other so for example if 1 week i do regular deads on back day i replace stiff legs with lying leg curls but i keep in goodmornings and add a set of those. as for a deadlift replacement i put bar rows 1st that day and simply add 3 sets @ the end of back trainming before biceps of rows with a wider grip , lighter wieghts and bring bar more to mid chest rather than my waist .
last thing to mention is if you dont wiegh much and can easily do your own body wieght on pull ups / dips even after the other previose sets then just add wieght with a belt .
DONT DO ANY MORE ARM WORK THAN WHATS HERE !!! ALSO IF YOU NEED A EXTRA DAY OFF THEN THERE IS ABSOLUTELY NO PROB THERE , IN FACT IT WILL BE GOOD FOR YOU !!!
