Aloha Uly,
Yeah, reaching around to the kidneys is a real bummer!

You are detecting and working on
that body in the mirror. It's not your body, it that body, there. Anyway, you SF that body. If you need to work on C7 or somethign in the back of the body, shoot through the body to that location - no need to put your arms into pretzels.
Much Love,
Shawn
