There's one where you keep both of your hands up close slightly above your eye brows. Thats the one we use at the gym. It also used in most of the tutorials on internet. and there's one where one of your hands close to your chin and the other more forward slightly above eyebrow. I usually see this one in a book that im reading and in some tutorials on internet. i am a bit confused...can some one explain to me why there's two different stances ?
