Hi I'm new to these forums, a friend told me about them a while ago and recently I have been having problems with lower back pain and wanted some feedback, as I am stumped as to the cause. The pain is very local in the lower back, only hurts when I bend suddenly, and is not debilitating, but at its worst makes me incapable of doing abs or back exercises for days, and only goes away if I skip lifting days that involve the back. I've been lifting seriously for about two years and have never had back problems before. I'm moderately musculed and very well toned but not huge body type and my workouts have been pretty consistantly the following for the past six months.
arms day-4x6 of three kinds of bicep/tricep. 4x6 close-grip. 4x6 forearm stuff.
back day-3x8 frontpulldowns, 3x8 backpulldowns, 4x6 bar shrugs, 4x6 db shrugs, 4x8 forward/side/back flies, 4x10 back hyperextensions, 3x8 bar raise
chest day-4x6 flat/inc/dec bench, 4x6 db pullover, 4x6 flies, 4x6 bar dips
legs day-4x8 calf raise, 4x6 squat, 4x8 seated leg curls, 4x8 seated leg extension
abs(3-4x a week)-4x20 ball crunches, 4 set leg raises, 4x15 twisting crunch, 4x6 vert leg crunch, 4x15 hanging leg raises, and 4x15 cant think of a term for it but the oblique thing where you lean to the side with a plate.
I typically do the arms/back/chest no more than 2x a week, the legs once, and the abs 3-4. I'm guessing the problem is in an ab or back exercise but
if anyone has a clue which of these I may be overdoing/doing incorectly to cause lower back pain I would love to know as I am immensely frustrated with having to skip lifting days. Not really looking for a critique of my workout in reference to anything other than back injury right now either by the way, but any help is appreciated.
