We test 3 things for power. A vertical jump A seated med ball chest pass and sit up med ball throw
So many times in my career I would try and get kids to do a certain movements and I’d get frustrated because they couldn’t figure it out. Now I’ve come to the realization that everyone moves differently.
Rotational strength and velocity is one of the most important things there is in throwing and hitting.
If you aren’t strong and you dont have the intent to throw/swing hard, not alot else matters because those are the two big foundations.
I love using a broomstick or PVC so the kids can actually focus on moving better rather than trying to hit all the time.
I think external cues within a team setting would be the way to go. Tell them to hit oppo home runs
