No on opening hips up before plant (unless it is just in their natural motion. Hip rotation is caused by a great plant. Trying to physically engage hips is a waste of time in my opinion but it works for some.
Try Trebuchet and Spin Doctor videos. The plant is difficult to learn because the brain doesn't like the idea of being off balance. That's why everyone moves over top of the plant foot. It takes a long long time to get, be patient and always be working on it.
I'm starting to think that if you didn't participate in some activities as a kid, the idea of bracing is really foreign to your body and brain.
But we can really look into the attribution of this from a larger format of data.
Activities that involve bracing we probably did as kids.
Sliding.
Good ole slide tackle.
But that's sliding on the ground!
It's a brace that turns into a slide.
So where am I grabbing that one from?
Ever been ice skating? Hockey stop. that's a hard brace. Snow skiing, when you carve/turn, you are bracing.
Really just need a list of activities that a brace is used, even if its not a brace like we are actually doing. Because its drawing from that feeling of how we are destroying the energy.
When we are throwing in disc golf, we are trying to brace hard enough to not fall through, not fall back, but stop in a way that the energy wants to drive vertical.
I really think we can figure out a way to teach bracing to people who started later, but its finding other activities that people need to do to feel the brace.
Most of the time its just explained so poorly, not necessarily due to lack of understanding, but because words are hard.
Annoyingly I just illustrated this all in my head on how it works.
But, I dont' draw things on the computer. If I did, all this would be SOO much easier.
