Last year, when I was practicing with the fall ball team, the coaches told me not to keep my elbow up, and have it down because it makes your swing quicker and more easier. The past month, I've been playing slow pitch softball for fun, and in the first couple weeks, I had my elbow up, and I did really good. But then I had my elbow down, and started to pop everything up. So yesterday, I remembered to keep my elbow up, and I started to do really good again. Is this just me? Or should I really keep my elbow down? If so, why is it so much better to have it down than up?
