I have been training for a while but have recently hurt my lower back (Herniated disk L4-L5). I have always favored the big five exercises to be the core of my workouts (Bench, Deads, Squats, Militarys, Rows). Since my back has become a problem, Deads and Squats Kill me the next day. Does anyone have good suggestions for Alternate movements? Or are there other techniques that could take the stress off my lower back? Any help would be appreciated.
