I'm no expert, but have recently gone through 3 separate (yet equally stupid) shoulder injuries. None of which can be blamed on LP.
Shoulder Rehab | Mark Rippetoe
This video is gold.
I hung motorcycle straps to a bar from my Rack to do this. (I did not have gymnastic rings hanging from my garage ceiling)
Dead lifts, on my first two I just dead lifted every session when I couldn't squat.
On my third injury... I bought a Rogue SB-1 (aka safety squat bar), so I could continue to squat. I like it it helped.
There are a couple of other good bars. It was like $400 plus $80 shipping. I'm happy with it. It allowed me to roll my back squat in much earlier. I bought it more for that "next injury" than the current one. I also have a daughter with a shoulder injury.
Meshuggah has this one:
I have the older version of this one... IIS 7.5 Detailed Error - 404.0 - Not Found
(an older Elite FTS Yoke Bar ( SS Bar).)
He mentioned 3 in a post I can't find, including the Elite FTS and my SB-1.
Camber is important. It feels much more like a high bar squat, and there is an Odd "push forward" as you go up. (aka keep weight on your heels) You don't notice the push until you have some plates on.
They are longer than you expect and much more awkward... especially with a hurt shoulder.
I had to build a rack to hold bars because of this purchase... still worth it to me.
