Joe,
Sometimes I see golfers stop their backswing at the top and check their position. What can I learn from this?

Hi Chester,
Some people prefer to check the position of the leading wrist. I prefer to check whether or not the shaft is on the same plane as my leading arm, and also that the clubface is not overly open or shut.

Jody, my Evil Twin, what is your opinion on this?
Answer: You can learn how many hands you have, and which one is wearing the glove.
