So last summer I blew my back out pretty bad, and just within the past Couple months have been trying ti dead lift heavy and get my dead max back up, however every time I start going up in weight I tweak something and feel crappy for days or lose strength by the next week.. so im considering swallowing pride and just dead lifting higher reps and not going higher than 315 for reps. Do any other of you experienced guys do this? I'm mostly curious if you see benefit from light weight Deads and refraining from going heavy, or if I should find another movement to do my best to supplement for Deads.. thanks in advance for any replies.
