Bro forearms are easy as hell to build. Go to ironmind (just got their latest catalog yesterday
) and get a number one and number two gripper. Do a couple of sets of five two or three times a week with em and your forearems will blow up.
Also I don't realy agree with your rep schemes. My philosophy regarding training is when in doubt, keep it simple. My arms never really wanted to go until I started using big weights in the standing curl (with strict form of course). If you are only doing curls twice a week following a 5x5 rep scheme, as your working weight increases so will muscle mass. Just about any strength gain besides that of a 1 rep max is gonna result in some hypertrophy.
I just don't buy the 'low reps only stimulate the cns' theory. Look at the old-time super freaks, guys like John Davis and Doug Hepburn were the some of the strongest and most massive men who ever lived (before there was even dianabol too). These guys trained primarily on basic compound and olympic movements using big weights for low reps. Paul Anderson squated 1000 pounds before fred hatfield ever stepped foot into a gym. Granted these guys were all genetic supermen, the fact that most of us as genetic mere mortals train completely opposite of their time-tested methods shows the somewhere along the lines of time real world training theory AND ART got replaced by the moronic ramblings of pencil necked excercise physiologists and kinesiologists.
Sorry about the rant, I drank too much coffee over the last 24 hours, but I still feel that too many people make weight training overly complex. Get a copy of dinosaur training, and look at some the records set in mid 50's. It's really sobering to see how much weight these guys were puuting up before steroids were common, contrast that to today were you see 170lb kids juicing just to be able to squat 300lbs and tell me what the fuck went wrong????
