[Trig]

Speaking as a student, I think it is very hard to change the mechanics of the swing. Over the years I have a difficult time shedding old habits, and they still creep back in. It can be done, however. Some things for me take a long time, then one day it just clicks, or, hatches from the incubator if you will!

Sometimes changes are impossible if there is some basic fundemental getting in the way. A good teacher hopefully spots these right away.

I have a friend who is struggling. He just had a lesson and I was amazed that his grip and setup were never addressed. He has his right hand very weak and really on top of the club. His right forearm is very high and off plane at address. His stance is extremely closed. None of these things were brought up in his lesson. And he wonders why he can't make a move!
