I was told that the rotation of hip and shoulders can not be separated. That I do not know what I am talking about. I have a flexible waist, even at 66 years of age. I said that rotation is comprised of a sequence like a whip. The hands whip the bat-head last like the tip of a bull-whip, but the whole body acts like a sequence of that whip. I just accidently found a video that talks about it by Antonelli. So either both of us are right, or both of us are wrong!
