What are some weight exercises for thoracic spine mobility as well as core?

Apart from some of these stretches, I am doing a form of punching exercise where i take a cable and stand at a slight angle facing away from it, do a slow punch and twist body, extending scapula further away from the machine.
It feels so good for my spine.

I also do back extensions, not quite there yet to do sidebends on it, scary shit.

Basically do all that shit with a single kettle bell held in one hand, and switch hands and sides.

Turkish get ups are great too, it will take months to reach even a small bit of weight. Check Mover's Oddysee on YouTube.

I forgot to say that you can do stuff like single limb versions of reverse hypers, hyperextensions, leg extension/curl, farmers carry, overhead press.
