He needs many things, but being that I'm not his parent, I have to pick and choose my battles.
That's depressingly serious. But there's ways around it. Does he train at a gym with a pool? Hydrotherapy (I think is what it's called) would be good. Anything that cushions the impact while still allowing him to work his body in an aerobic, cardio fashion.
I don't mean in water deeper than he is tall - I'm sure you know that though.
