Now you are being disrespectful. It is spelled humerus and it is the upper arm. It is basic anatomy, which you need to learn if you are going to continue posting here; Wikipedia is perfect for that.
I already told you where the humerus needs to be in order to keep it from getting behind you (that movement away from the body is called abduction; look it up) and posted this picture of Nicklaus and an explanation (if you don't know what the clavicle is, look it up).
"Jack Nicklaus shows how to keep the right arm in front of the body with a very high right elbow: don't let the humerus get in line with or behind the clavicle."
I don't want you cluttering up the forum asking the same questions over and over, not paying attention to the answers and not doing your homework. We aren't here to spoon-feed you stuff you already claim to know or can easily learn on your own.
