When I started this course, I blew through HSPE1, but now they I've been around longer I understand more about the important of form, so I'd like sime some feedback on the mobility.
I realized there's a nuance about the shoulders I don't understand, and I'm not sure what is right. With overhead shoulder mobility, there's a limit to how far back I can go with my armpits facing forward (at least, that's how I think of it). To move further back, my arm pits go outward. I think of it as closed shoulders vs. open shoulders, but I don't know what it is really called or what causes the difference in the shoulders.
To my eye, the model student's arm pits are outward, so I think this is correct.
But I'd like to get confirmation and understand the shoulder mechanics behind it.
Also, should I lean forward more?

"Open":
Thanks!
