Supination is the outward rotation of the forearm with the palm facing up or outward. In the golf swing, lead arm supination through impact is associated with face opening and fades or slices. Trail arm supination helps rotate the face closed for draws. The interplay of both arms pronation and supination determines face angle at impact. Many instructors use the throwing a frisbee analogy for trail arm supination on draw shots.
