I am personally built to deadlift (450) and squat (400)at a weight of 165 but I beleive that my lower back gives out way before my legs in the squat or my upper back in the deadlift. I feel that if I had a stronger lower back I could increase the weight signficantly. So im asking for some low back exercises suggestions. I currently do reglular hyperextions (sp) and good mornings for my lower back for high reps of 15 or so. Im taking a bodybuilder approach to training right now so I am looking to put muscle on rather than gain strength.
Any advice would be appreciated
