My chiropractor said not to do hypers. He also said no squats, no rowing, no overhead pressing and to be very careful not to arch when benching. He recommended I walk a lot and showed me a handful of stretches. I'd already found that squatting wasn't an option and that seated rows were something to be careful with. I was so pathetic that I couldn't sit up in bed without using my arms due to the pain it would induce in my back and just standing still in a shop queue would hurt.
I joined abs and fitball classes, which did include reverse hypers, to start to strengthen my core and they gave me some partial recovery. My biggest recovery period began when I started to do seated rows and also a full pull right the way back on the seated rowing machine, kind of like a seated good morning. I also started to do very light squats. It was a bit scary and sometimes my mind would just refuse to do a weight I knew I had the muscle for. These exercises did for more for me than anythng I'd tried before.
I finally added in deadlifts and bent barbell rowing about a month ago. The chiropractor was appalled at the idea when I saw a couple of days ago until he examined me and said that I was in the best state he'd ever seen me. I can now do such crazy things as bend forward and pick things up without pain.
