Oh, and for the shocks, it should be something he chooses and is okay with. You want to stimulate adrenaline, but not do an activity that's so upsetting that it's distracting.
I do the shower hung, but first I decide what I want to be working on when I get out. I focus on that, get the "shocks" done and get it and I'm ready to work with more of brain engaged.
If you doubt the friendly shock idea, don't do it. But, I have found it very useful and it's one of the only things that works in a really short time span.
