Hello Comrades! My son is 17 and is a very good pitcher in high school. Since the shoulder and other arm parts are heavily taxed by pitching I was hoping someone could give me some advice on what kettlebell techniques etc… would best help him develop better skills as well as help prevent injury. I have seen somewhere a program for this but it wasn’t here at the "D Door site" so I don’t trust it. Thank you in advance.
Jim
