Not much changed with approach to different exercises, we increased the weight and distances as he grows older. Definitely heavier than his peers. Heavier in a way that a 30 lbs. suitcase feels lighter than a 30 lbs. dumbbell.

Rise in Broken Bones in Children
A lot of reasons for this probably, this article links it to calcium, and there might be some truth to that. I think the bones not being worked are a big factor.
If the argument is that there was a rise in youth sports, I would agree with that fact. I do not think youth sports should be relied on as a bone building activity. There are many reasons for a decay in bone strength. The best thing you can do for him is help fight against modernity.

Don’t optimize this stuff, don’t set out to break records, build the bones over time. Small iterations and every 4-5 weeks do a grueling week of heavy lifting. Be careful!
Notes
Started to use an axle barbell, lift and carry for distance.
Made the throwing weight heavier and the quality of the form to throw it go pretty good.
One hand hangs, really liked these.
Weighted walk with head weight is still the king of exercises.
