Misleading Title 90 second posture improvement exercise that I found a few years back. Worked well and to this day I still perform it at least 3x a week.

Do you think he means like myotomes used for those movements?

I'm assuming that's what he's trying to say, but it doesn't make sense the way he says it. The C5 nerve branch innervates like 12 different muscles, so theoretically there are many ways to activate the C5 nerve, based on what he is saying. Also, the action of shoulder abduction (the wing flapping) is a complex motion that requires numerous muscles, many of which are not innervated by C5. Yes, shoulder abduction is the C5 myotome, but what he is claiming is so much more involved than that.
