Coaching Hack — Have people stand on 12-18” boxes for overhead slams.
We all know that med ball work is great for training power, learning how to link the upper body and the lower body together through the core. But a lot of times the biggest problem I personally deal with is people not throwing with intent or max effort.
To a degree, having them stand on a box helps to alleviate that. In order to still be able to catch the ball on a rebound you are going to have to throw with more intent. Plus, it allows for a full follow through with the arms.
