Agree with Truman. Weighted balls should be supplementary to strength & conditioning basics - squats, deadlifts, power cleans, plyometrics - as long as someone can show him how to safely and properly execute those movements. Then, as he builds up a strength base, add in the weighted balls.
I see you are doing Jaeger-style long toss. I'm a big believer in that for arm health.
I've never done a weighted ball program, but it's hard to argue with the results at Driveline. The research they do at their facility is phenomenal.
