I'm a freshman catcher who has been timed at 2.14. I was clocked pitching 78. I have good footwork which I work on with my catcher coach, but I need to improve my arm strength. Many replies have said that this is one of the keys to having a good pop time. My question is does anyone know how to get my arm strength better? My dad has told me long toss which I do every other day, but what are some good exercises I can do to improve my arm strength. Thank you
