Came across these two "tips" over the years. As we get a bit older and flexibility becomes more of an issue, I've heard that "opening" the back foot will help get a bit easier hip rotation on the backswing. But... I've also heard that opening the front foot can aid in getting the hips to open easier on the downswing. Since I'd rather not waddle like a duck during the swing if I do both, is there a preference between these two scenarios? Besides working on the actual rotation with actual physical exercise?
