Recently I've decided that I no longer wanted to dead lift the kind of weight I was used to putting on the bar. I used to start off my back workouts by dead lifting 135 as a warm up and then building up by increments of 90lbs all the way up to 495 for 2 reps. I never really had any back problems, nor did I ever find myself really straining to pull the weight, but I felt as though eventually (because I am not training for a sport and don't really have to lift that heavy for anything but bragging rights among friends) something might go wrong. I decided to simply stick to doing sets of 225 until failure and working in back extensions as my rest. Would that be a viable way to maintain a decent level of strength?
Any advice is appreciated.
