From what I can tell, he's basically just giving you movements that stimulate muscles that are ennerved by the C4-C6 vertebrae. Ignore all the crap he's saying; you're still engaging (albeit very lightly) the muscles that support your back, spine, shoulders and neck while stretching the ones that are typically contracted all day over the computer. This may not correct any serious deformity caused by hunching over a computer for extended periods. For that you need to go to a physical therapist. But for people with just a little tightness or that have difficulty keeping correct posture, it can certainly help. But so can a lot of other things.
