 Hi there, I'm using a training tool, this alignment shirt, to help understand the function of shoulder turn as it relates to how I move the golf club. So what does that look like? Well, I'm going to stand and face you. If all I do is move my arms, notice that I did not get much turn in my shoulders and I move my arms very narrow to me. Now if I think about moving my club in a wider circle, look what happens to my shoulders. Much more turn and that began to engage my lower body and my weight shift. So think about what you want to do with the club. I don't want a high narrow swing because that does not involve my body. I want to swing the club on a bigger wider circle, I get my shoulders turning because of that and they turn in both directions. Very athletic, lots more power, hope that helps.
