I sort of do the same thing, while walking- typically very early in the morning (I have a thing for watching the sunrise) I will almost always breathlessly speak/sing some phrase that fits the cadence of my steps. It changes daily, and sometimes is as simple as "way to go, boy" or "go long, go strong."
It helps with the focus. I also use it to regulate my breathing while running (which I'm not really doing a lot of yet since I still have some weight left to lose).
I just started with Harry Potter with my Son. He likes some of it but is scared a bit too (he's just 7).
