I'm posting this on here because I forgot my login for MD and too lazy to retrieve it. But I was looking at his training video for chest and it's a typical bodybuilders except without the heavy movements. It is what it is. Not that my opinion matters but the dude had a pretty good shoulder injury and throughout the workout he was on almost all machines, all closed chain and fixed (smith, chest press, pec deck, etc). Little room for muscle recruitment to help the actual stabilizer(s) get stronger, regain mobility and flexibility. It's all isolation. Anyone with a shoulder problem like this or similar shouldn't isolate. We do about 5-6 either rehabs or post PT rehabs a year and the last thing that's recommended is machine work and very careful to not isolate, overhead press, no straight bar (unless it's a bamboo press for the rehab).
In his back lat spread he said he had a hard time pulling out the right lat due to the injury and I couldn't read all of the report (because it was blurry).
Long story short, don't rehab on machines, strengthen stabilizers (subscap especially), lots of flexibility movements, use free weight for primary movers (again, not machines).
Why did I post this? Because bodybuilding hasn't progressed in 50 years and rehab just doing trying different machines until you find one that doesn't hurt. Just because it doesn't hurt doesn't mean the injury is healed. I don't know how he injured himself but it looks almost trauma-like.
