Yeah I think I'm on board with all of this. I can't make my body do it yet properly but I'm really feeling it when swinging objects and seeing it in every single video. It's definitely an advanced thing to think about which is why there might be confusion/pushback, but at the same time it seems so fundamental to a proper hit point. I can also feel blood rush to my fingers if I swing with an open hand, which I've never had happen before like this.
I can feel what you mean by you're just rotating the arm into a powerful position at the hit...it feels so natural when I walk through this or practice swing through it. The forearm/wrist want to pronate when I move to my centre so I stay leveraging the arm, then as I extend away they supinate back to neutral and this is the hit point you want to end up at naturally. It's the same thing if I think about my lead/bottom hand on a baseball bat...just the bat is round so I never have had to think about it rotating on its own axis to the same extent. A golf club though...that head goes way off plane and snaps back right before the ball. And I trust this because I started hitting balls at 4 even though I don't golf anymore.
I think my brain just won't let me throw with the forearm/wrist below my elbow with the proper plane maintained, because I'm trying to throw "flat" relative to the ground or my line. Yet I can feel the increased leverage when I practice swing. Should I practice spike hyzers to try this plane? Should I just try to throw with the disc at my belly button to make sure my forearm stays on plane with the upper arm?
I'm just getting this continued disconnection at my elbow as my hand/forearm rise up above that joint. I know what to do, I can feel the leverage when drilling it, but my body won't let me throw a disc like that. It's only been a session or so though, but the nice thing is when I throw the disc I feel like I've got more in the tank that isn't making it to the disc. I can feel that missing transfer of power in these.
Oh I put a few blue dots on that Wiggins image where it feels to me the nose of the disc is...does this seem right? This is what it's feeling like to me with this disc turn, and where the of the disc will pop out to end up being down.
