The Hitter's Back Elbow

I have a very strong opinion on the back elbow. For many years, actually decades, I have constantly heard parents, coaches and managers yell out to the batter to raise the back elbow. Let's just hold on for a minute here. I see younger and older players as well, raising their back elbow up to the height of their ear. (That is totally absurd) What I teach is to make a fist with your hand that will be your top hand when gripping the bat. Now raise the fist to about the same height as if you were going to punch a balloon that's in front of you and across from your chest. That height is an ideal starting point for the back elbow! In other words, the back elbow should be slightly lower than the back shoulder.
