I had a couple of very good reads yesterday. They were basically related to the pivot. A lot of what I read is complimentary to 7-12 Pivot. AFAIK Homer is on the money when he talks about the pivot (what a surprise

). But there's more to say about it than you find in the yellow book.
First out is Allison Thietje & Co. Very fundamental, very basic, very clear and also very practical. This is low hanging fruit for teaching pros. She and her colleges have developed a few anatomical fundamentals for correct movement patterns in the golf stroke. It relates to damage prevension but those who need them will likely strike the ball much better too. Go
here and pick from the menu About Us-> Motion Memory Golf Live Seminar. The first 2-3 chapters of the seminar is absolutely worth the time.
Equally interesting, but with a different approach and a very entertaining style of writing is Kelvin Miyahira. He is a speed trainer and very much into golf and tennis. In his recent monthly column he makes case for the not so pretty pivots that we can see on the tour. There's a lot of food for thought in several of his monthly columns and his Tiger analysis is a great read for anyone that doesn't go by the name Hank Haney

You can find Kelvin's columns
