ok dude, there are a lot of problems u have been outlining and im sorry no one has even responded to them.
let me make a short list (everything is quoted by u):
1.) lower back pain
2.) inability to do deadlifts on a weekly basis
3.) right bi and into ur pec is a problem
ok, now i dont know anything about #3, i can say something about #1:
firstly stopping deadlifts is no biggie. im not gonna be doing deads any more. as long as i do a variation of deads its fine. so i will be doing deadlifts next year at this time.
u mentioned lower back pain: i think u should read up Eric's sticky on that. ice it and warm it. i had lower back pain too. but im fine now.
just my 2C.
get well soon bro
