“Bones only get as strong as they are asked to be, and that is loading the bone making the bone work against gravity.”
Ages 6-7
Start with basic bone loading exercises for ages 6 and 7. Did not put an emphasis on form and technique. Do loading exercises that are simple.
Dead Hangs
Overhead Holds for Time
Holding Weight for Time
Carrying Weight for Distance
Walking with Weight on Body
Carrying Overhead for Distance
Towards the end of the time or distance his experience level is at, these exercises should be challenging but not hard.
25 weeks through the year with two seasons of loading. Set aside 3 times per season to do a grueling week. Everything else is small iterations of loading.

As he gets better at controlling weights, increase the weight, add time and distance. Introduce different throwing variations as well.
Notes
Distance is a goal of moving weight 50 yards. Work up from 20 to start.
Be able to carry 50% of body weight in each hand for 50 yards twice per year.
Hangs work up to a minute or more. Add weight after a minute. Helps with hand strength the most.
I can’t find the study, or I would link it, but some study by one of these big deal places found that girls that did gymnastics had the same bone density as male bodybuilders. The exception was their skull bone density, it was the same as all the sedentary test subjects. Put weight on his head!
Started both years in March and finished in June, started again end of August until end of October. Big breaks between seasons.
