"helps wonders with any shoulder issues"? (emphasis mine) That's a bold claim. There are a lot of different shoulder issues. I never found that all that YTWL stuff did anything useful for my shoulder at all (torn labrum from Judo), but doing stuff more like the article (closed chain) and doing some of the flexibility stuff from a 'gymnastics for beginners' type program ("Elements" from GMB - in the end I didn't like the program but I still do the warmup/cooldown) also really helped. Also not getting into impromptu bench pressing competitions with rugby players at the gym was a pretty good idea too.
