Ok, a little background first. Been a skinny bastard all my life, and since I can only do so much about the bastard part, I decided it was time to be a little beefy for the first time ever. I started lifting in early February, typical arms & chest yahoo you've all seen at the gym wondering why he can't pack on the poundage. Long story short, I tried to push a little hard one day, gave myself an exertion headache, and wound up here trying to figure out exactly what I did to myself. Started reading, cleaned up my diet, ate my face off, hopped on WBB 1 and haven't looked back.
So, as to my question, I've been progressing up in weight on all the exercises, starting out easy, doing warm up sets, the whole shebang. But as soon as I try to throw some real weight on the bar for french presses, my wrists hurt like mofos, my form gets awful, wrong muscles try to pick up the slack, more pain, etc etc.
I'm guessing cable tricep extensions aren't a full substitute, as they involve fewer muscles, but I'm looking for some more options. Thanks in advance!
