Just some general thoughts regarding shoulder health.
Nothing new here, since you can pretty much find the same things spread throughout articles.
I don’t think It’s enough to just say “do [twice] as much pulling as pressing”. I actually have no thoughts on volume at this point.
My thought at this point is that for every movement of the shoulder, you should also train the opposite.
Protraction should be balanced with retraction.
Elevation should be balanced with depression.
Upward rotation should be balanced with downward rotation.
These go both ways. If you’re doing overhead presses, you should be doing pullups. But the corollary is also true: if you’re doing pullups, you should be doing overhead presses.
Although it’s not quite that simple. Pullups always involve downward rotation, and may involve retraction and depression. Overhead presses always involve upward rotation, but may involve elevation and protraction (at the top).
Besides the shoulder movements themselves, you need to make sure the muscles are balanced. If you train the muscles involved in protraction (e.g., the pecs), even if you don’t actually protract while doing those movements, you should train the muscles involved in retraction (e.g., the lower traps).
That’s normally taught with the bench/row pairing. But I think there’s also the deadlift/pull and pullup/pulldown pairing.
I’d say the same thing could be done around the elbow joint… curling movements (even if back work) should be balanced with straightening movements (even if chest work). You can probably look at the knee and the hips the same way.
Anyway, the shoulder stuff is what’s mostly relevant to me right now.
