Note to the wireless universe out there: if you want your body to be in good shape, don't be an athlete. Seems like a smart plan, hours of conditioning, playing, and weightlifting should make having an amazing bod easy. That's a dirty lie. What actually happens is the total destruction of your body, making you feel like a senior citizen. Hence the hip injury prevention exercises. And now the shoulder prevention exercises.
I never did these in college but watched all my hitters go through this every day. I thought it looked way more fun than my own rehab workouts. I feel like I'm about to prove myself wrong.
