Hey sam, this was such a great insight that I believe everyone should know it.
To that end, I wish the title was something like, "People are getting it wrong. Core training isn't about creating movement, it's about preventing it." That would have made me (and in my opinion, others ) want to click on this article more.
Just to be clear, I'm not criticising your title skills xD, it's just that I genuinely believe that this article should go viral! Maybe rewrite the article someday with a more clickbaity title?
Anyway, thanks for this very important article. I'll carry these insights for the rest of my life!
