I'm a new contributor and an anatomy/physiology nut along with GSEM and PGA affiliation; I am compelled to clarify that wrists cannot rotate. They can only flex, extend, adduct, abduct, or circumduct from standard anatomical position. I have trouble understanding GM terminology. Only the whole arm or forearm can rotate. Forearm rotation is termed supination or pronation and whole arm rotation is termed either internal or external rotation or, in some circles, lateral or medial rotation. So is so called wrist rotation a form of forearm rotation or whole arm rotation. Mechanical advantage suggests that forearm rotation is great for opening jars and manipulating most faucets from hot to cold or on to off but not so great for manipulating a golf club. Whole arm rotation is much more massive, powerful, and precise than forearm rotation during a golf swing. Please explain or reply if my words provoke anyone.
