They appear to have boundless energy and enthusiam for you and your golf. How dull to work with someone who stands and watches you hit balls and passes the odd comment every few minutes. You need to discover how deeply the coach has explored the teaching side of the game. You need to be convinced that the coach has a structured approach to teaching. You need to avoid a coach who reads something in a magazine on Thursday night and then proceeds to experiment with that 'tip' on you on Friday morning.
Good methodologies allow for flexibility.
These programmes are structured in such a way that they do not try to force one golf swing on to all players. The methodologies appreciate that one swing does NOT fit all. Look for a coach who has a flexible methodolgy that will cater for your age, body structure, personal ideas on the game and so forth. I have paper and a pencil with me at all times during my golf lessons. These two seemingly unrelated facts are the result of something forced upon my unwitting brain many years ago.
