That's part of the issue, you don't know what shape the people are in prior to surgery and what they do for recovery after the surgery. All of us are a different group of people. We get up and go to the torture chamber without anyone telling us too. We just do it because we're a bunch of sick fucks!
I've been through so many PT sessions prior to and after surgery. They have their moment but for the most part, none of those sessions stand up to a grueling workout.
@greaser13 if you don't know, most of my neck is fused, C3-T1, and L4-L5s1 are fused. I also have Ankylosing Spondylitis, which is responsible for some of my cervical fusion. I haven't squatted or deadlifted in many years. I keep telling myself it's time to start light and see what I can do with those lifts...we'll see. I'm 54 and I've accepted where I'm at with everything. Upper is still decent and I'm still fairly strong.
