Can’t hurt. My son’s right side of his body was much stronger than his left in the core and back. The trainer added exercises that made the left side stronger (in addition to the scap work). The weak left side wasn’t able to pull to match the right resulting in hitting and throwing with his left shoulder up. That resulted in the Teres Major/Minor scap area getting sore and vulnerable. Had he continued without fixing it he would have likely made his own adjustments resulting in a different injury.
Good trainers will evaluate the entire body and chain to see where you are going to break down. Then they plan to strengthen those areas before implementing things like velo programs.
