To skip the good news and get right to my problem, skip to the BUT about five inches down.
So over the last 4-5 months I've gone through this cycle:
1. Going hard, like a powerlifter! Old shoulder problems return.
2. Going carefully, trying to limit every movement before clicks, pops or pangs of pain. Not quite working.
3. Success! Baby steps! Feel like a beast!
As an example of what kind of baby steps I had to resort to, I'm doing sPL and HBP against a wall and, wow, does it feel good. Parts of my shoulder are way over developed and parts of my shoulder are way underdeveloped, it looks like I needed this extreme step backwards to get everything working. I've done wall push-ups before (Convict Conditioning), but i needed the mobility work of GB to get things sliding and turning as they should.
The last few workouts I feel amazing! No clicks! No pops! No pain! Plenty of hard work and sweat, even though I can rep out full push-ups for fifteen rep setss... these fifteen rep sets of wall push-ups are surprisingly challenging because there are parts of my shoulder that are challenged to grow by such a light resistance. I'm getting stronger each week and I feel great.
I'm doing MN, SLS and FL at the regular beginning point and not the baby step point because my body is fine with those movements. I'm doing SL at the first baby step stage that was posted here and it's doing great things for my ability to flex my spine and activate my glutes instead of my adductors.
Very happy with how my workouts are going, body finally coming together like I hoped when I got GB.
BUT
I can't figure out an ultra-baby step for RC. I tried sitting on the ground and doing the motion, but that's still too much weight. There's still popping and pain. I can do the motion without grabbing the rings, but any weight is too much weight.
So the one ultra-baby step I figured out is to statically hold the finished position with a pull-down machine. I'm starting light and REALLY concentrating on flexing the target muscles and so far it seems to be a worthwhile exercise. I can increase the weight easily enough.
Any other ideas? Anyone else have to ultra-baby step the RC/PE1 movement?
