Now I'm thinking:
- Plant heel down = max reachback
- Rear foot off ground = disc at right pec/max elbow extension
- hips clearing = hit
Does this sound right? Just looking at that GG picture made me rethink the footwork/hips vs. shoulder swing/pull through timing.
I see it as reachback as front foot is going out there, equal and opposite, "move around the disc". Max reachback at toe touch position. While at toe touch, weight is shifting from back instep to the still "hovering" front side that is toe down. The weight now transfers to the heel (rear foot should feel like it's already de-weighted). You're trying to be reached back
still at this point, but the weight transfer is now tugging your hips open.
At this point your weight is on your plant foot and your upper body is coming to the right pec position. Now I feel like my brace foot has accepted and is now countering the momentum, pushing back against the instep. The right side of my torso has to open up from my hips starting to open, and I'm at the right pec position. So I let that open my torso and I whip my shoulder as well. Boom.
You need that weight transfer early, it was weird to figure out. Your front side has to accept the weight and be countering it during the hit, so you have a firm axis for your shoulder to tug against. What I listed is how it feels to me...not sure if it's exactly as video, should be close...but it's how it feels when I do it.
As far as how the transfers feel, I feel like my back knee moves forwards and compresses a spring that goes from my left hip to my right hip, which is parallel to the target. That doesn't make sense because hips don't compress...but once it hits a certain tension point at compression my hips get redirected open, towards the target. I really try to be reached back and I feel some tension between my right hip and right armpit, a little more on my back than the side. This is the main muscle that I feel things in, rather than my shoulder socket.
The hips don't feel like they collide, and I don't feel the extension in the plant leg...it just happens. Figure out the body positions, try to swing a baseball bat or just go through an in-balance rotation without any object, from neutral to hips forward. Figure out how things should clear and how to end in balance. Once you know how it should feel, it just works. It's like heel rotation or follow through...once you get into the positions before it, the rest just happens.
