Do not blindly trust the source of advice. Today I talk about something a tour pro said as advice in a magazine, it was so bad I had to record this video about it. You have to remember that most golf instruction you are going to read or watch in mainstream golf is going to not be in tune with the PPGS.
This bad piece of advice is about head position post impact - keeping your head down after impact. What do we say? Come up from the golf swing as fast as possible after impact! You cannot come up fast enough after impact. As fast as possible, like a pop-tart out of a toaster. Keeping your head down till your arm hits your chin is just twisting your back unnecessarily.
