If you have time, could you share (public or PM) how you rehabbed the should with the labrum tear? I can only do so many RC band exercises.
Basically the "Retard-Method".

Honestly, I went to the gym each normal day, and only did what I could using little-girl weights.
So for many months I would bench with the bar only. (Then add easy bands, etc).
I would do smith-BNP's with the bar only and maybe some 2.5's.
I would use the rubber bands and do stretches I watched on Youtube..
I would do the over-head broom-stick stretch (Dante's 50 reps) until I could get it behind my head, etc.
It was basically just letting it heal on its own while not stopping my normal movements. Many hurt like hell, but it was just letting heal over time. (Took about a year).
I have something going on now with it again (heard and felt a 'pop' like 3 months back benching 335, so cannot go past 225 right now (back up from the empty-bar again), and I use the 2-board padded block to bench with to keep me from going to chest.
30+ years ago when I first tore it, they went in and saw lots of scar tissue. So this keeps happening as I push it hard.
Will need to stop doing that one day...
