That being said...
The project is - in part - a playful exercise in the use of core muscles. Anyone who started as an athlete before they ever got into highly stylized martial arts understands the importance of the core in power generation. As I am want to say in my dojo, core muscles are the caffeine in your martial coffee. Doing Sanchin just with upper body movement? Sorry, but that's decaf. And Billy don't do no decaf.
Getting overly-schooled Uechika to find their core in their art is almost like trying to get a tone-deaf person to carry a tune. People try... Often the result is too much, not quite right, or just plain denial.
In some cases you get ridicule. And I wear those labels with pride.

The big problem with Uechi Ryu is that we do everything very, very SMALL. But to feel it, you have to start BIG. I use my examples in class. I take one peanut gallery label of "Uechi hula" and run with it. We have hula hoops in the closet of my classroom where I point out how it takes BIG motions to get the thing going. But to make it really hum, the motion is a barely perceptable shiver.
Getting from soup to nuts in your training is not easy. Getting started does not need to be difficult. In fact... sometimes a diversion can be downright fun.
My first female Uechi black belt was a bellydancer. Teaching her was easy. Her body just knew how to do certain things the way I can teach a musician about athletic timing without a lot of explanation. Moreover, bellydancing is just fun to watch, and fun to do.
So... here's a video of a "diversion" that someone sent my way yesterday. It isn't martial at all. Or then is it?

Enjoy.
