mon/thur= back and bi's.
start off with back goes like this
T-bar row- 3set 10 reps
pull downs-3sets 10reps
rev grip pull downs 3-sets 10 reps
Than on to bi's by now my arm are warmed up
Standing BB curls 3sets 8reps
concentration curls 3sets 10reps
Ez-bar preacher curls 3sets 10 reps
Then if i got any feeling in my arm's left throw in some hammer curls till my arms fail.
Diet not the best in the world but sure not the worst!!only supp's im on right now is a muit-V and been on a EC stack for 2weeks!!!!!!!1
Another thing I did was also lower my target reps and tried my best not to go to failure; just to get somewhere near it...
This is just a suggestion, but I'd make all arm work 8 reps and raise your workout weight accordingly... I had trouble growing when using 10 or 12 reps myself; I had to drop down to 6 or 8 depending on the exercise; just a suggsetion for arm work:
try:
Incline DB Curls 3x8
EZ-bar Preacher Curls 3x8
Machine work 4x8 or Standing DB Curl stripset 2x
It depends on what you want to do as your 3rd exercise really, personally i like to burn out using one of the cable machines... i get an EZ-bar made for the cable machine and do really high weight to near failure for 3 sets and then on the 4th set i go to full failure...
after that point my arms cant take anymore...
or
another one I do is standing dumbell curls, I pick a normal workout weight, take it to absolute failure (no forced negatives), then i immediately drop off 10lbs, I go to absolute failure, then i drop off another 10lbs and go to failure again...
Thats one set, I do it one more time and my arms are like rubber, sometimes my muscles hurt so much at that point i have to rest lol, it burns like your calves do when they are pushed hard...
Also, I dont know how your full workout split is; but I work biceps twice a week, if this helps a little bit, you may wanna try ever 3 or 4 weeks adding an extra set just to increase the volume on your arms, you'll know when its TOO much tho; biceps are VERY resilient muscles and recover very quickly...
