i would add that i still would not recommend significant loading and twisting. i would not recommend doing trunk twists with a loaded barbell on the shoulders. that would seem way too risky vs. any potential reward benefit.
i should also add that rotation can be deceptive. sometimes rotation shouldn’t happen in the spine but in the hips. think golfers who develop back problems. they are swinging way too much with their spine but with restricted hips the spine takes all the beating. instead, they should brace the spine properly, and have loose hips enough to make rotation happen there…
