The front elbow.

What does -- and doesn't -- it do during a high-level swing?

That's a question I touched on in my Rotational Hitting 101 DVD, particularly when I talked about the Running Start.

However, I didn't spend that much time talking about it because, in my experience, most hitters move pretty well, naturally.

Then my younger son naturally developed an inefficiency.

Then, and more importantly, I started talking to the hitters at HSSU and came to realize how much -- and how badly -- they had been taught about the front elbow.

As a result, I've put together this piece that draws upon an understanding I first started to develop during some conversations with Josh Donaldson that resulted from my working with Mark Trumbo and my efforts to help him.

The Front Elbow and the High-Level Swing

How do I decide what to write about?

To a large degree, I follow my obsessions.

And, ever since I left HSSU, one of the things I've been obsessed with is the Front Elbow.

In large part that is because fixing -- and refusing to fix -- a problem with the front elbow made huge contributions to my hitters' ability to be successful.

This piece is still a work in progress but, while I work on it, I discuss related topics in these pieces.
