My 2 cents and it's worked for me. Go all the way down with super light weight for therapy. Each week ease into a little more weight. I screwed my back up pretty good. In daily life it still bothers me at times along with sciatic problems ever since. But Deadlifting since I slowly built back up has not bothered me. I'm not 35 lbs away from the heaviest reps I used to do. I'm going to come back stronger.....dammit
But that said, keep the rack deads in there to keep the back alive...if that makes sense
