Mark Ottobre explains why shoulder pressing in a neutral position prevents pain. Pressing outside neutral overloads small external rotator muscles that can't handle heavy weight. A neutral grip feels lighter at first but lets you lift more safely because it avoids stressing minor muscle groups.

I would strongly recommend that your shoulder pressing, you stay here in neutral. That's why I actually don't program anything outside of here, because there is— for that reason, there's a lot of load on that external rotator, and they're small muscles, so you're not going to be able to load them as effectively. Where initially you're going to use less load being here, but the ceiling of what you can get to, because you're not loading up minor muscle groups as much, much more supported, much more stable. Here's a lot more instability. I mean, you've got to think of it as like if we were wrestling and your arm comes out here, you can snap your Externalize it very, very quickly. Here, you're nice and snug. Like, if I even put a lot of pressure on that, you're not gonna rip anything. Okay.
