Only posted a couple of times. In my area, not a lot of pitching coaches. Found one I'm interested in and asked if they teach HE or i/R. Their response was that the I/R was really bad on the elbow. The coach is highly recommended and has been very successful. I know my daughter could learn a ton. I understand the fundamentals of I/R but had not seen any discussion on here about pitchers arm injuries. Is tennis elbow common? Why would I/R cause more injuries than a normal overhand throw? Again, i'm a noob and want to guide my daughter in the right direction. I want her to be as good as she desires to be, but don't want to do anything that will put undo stress on a growing body either.
