I need some help on working my back... I hit my shoulders good (do side raises, forward raises, shoulder press), but hitting the middle of the shoulders, the middle back and lower back I don't know what to do. I have access to dumbells. I've tried squats and dead lifts before but screwed up my back twice on them.... and really don't want to risk around injury.... (I have no cordination what so ever).... I've also tried doing dumbell rows, but I can't isolate my back muscles, it feels like it's working my arms more then anything. I'm good at doing exercises where I don't have to balance, but if I have to balance and get corrdinated to hit a muscle I ussually #### it up badly. Any ideas?
