I don't think people fully appreciate how injuries limit what exercises you can do afterwards.
I had a double hernia when I was a kid, which got sowed up, which was the best technology at the time. I opened it up again while sparring in karate, it got sowed up again, and then 3 years ago moving a peice of heavy equipment. This last time mesh was put in, but basically, there is no recovery program like athletes go through in the NFL after ACL surgery or something. I'm not going to get back to some 95% number of what I was...
Basically I can't lift anything over 100lbs - end of story.
So there are some exercices that are just out of any regimin I use to stay in shape.
