Ok, so I have read from articels written several years ago by dave tate and louie simmons that you should press in a straight line, and not over the face, because this is the shortest bar path. It makes sense.
But then recently I read by jim wendler and metal militia that you should press towards your face, and NEVER pres towards your feet.
So why is this? Why do some say to press in a straight line, while others say never to do so? Why should you press towards your face as opposed to straight up?
