Learn English – What does the expression “body shop” mean

Well, I bit the bullet and asked the guy what the heck he meant (imagine that). Turns out he was referring to the oft-quoted teach a man to fish proverb.

He also clarified that this is not a common expression, just an idiosyncratic reference he invented and uttered spontaneously.

To become grounded in your body is a New Age-ish expression meaning, mainly, to stop over-thinking things — fighting natural processes with your mind — and allow your body to take over and process emotions at a more visceral level, thereby allowing them to work themselves out. Another way to put this is "Get out of your head."

I make no claims that this process actually works, but this is what the phrase means in context.
