I work with a lot of youth baseball players (15-17 yo). They always have questions when it comes to weight training and over head work. The most popular theory that I have been exposed to, is that it is not a good idea to incorporate any heavy OH lifting with throwing athletes. I have also heard from a few other professionals that this is not a major concern if the athlete doesn't have a pre-existing RC injury.
I'm curious to know how other professionals feel about OH training and throwing athletes?
