I want to cut and carve up my legs, but want to do so with out hurting my lower back. My back is not terrible by any means, but scared of dead lifts and to much weight on squats. I do squat some and do leg presses. my back gets tight, but no pain. I always try to stay in perfect form , but want to know which excercises i should stay away from. I was told clings and dead lifts is a no no for me.
