Dr. Mann,
Am sure you have seen Joseph Mayo of TPC Summerlin recent short video of how he teaches squat and rotation. Your thoughts or comments

It is on Instagram here http://instagram.com/p/BV-YQmRD8h1 Do you follow him on Twitter? With George Gankus he did a Vimeo video on pivot followed by two videos, the first on turning the sterum into the left arm followed by this short explanation on how to squat

First why the negative feedback? I have not seen you comment on any of this coaching. I find your work interesting and informative. And, Yes I have read your paper and watched your video These videos that I posted cover both how to shallow and rotate by squatting in a way never considered insofar as I can tell by TGM and two TGM certified instructors agree. Your work on pelvic rotation does not talk about how a tall backswing which lets on squat may be the optimal way to both flattening and pelvic rotation. Last TGM doesn't cover the movement of legs in making the pivot, after you squat
You do talk about tush line but as you can see Lexi goes past her TL
Golfingly yours

I forgot to mention the deep backswing of all these golfers as well

Last TGM doesn't cover the movement of legs in making the pivot, after you squat You do talk about tush line but as you can see Lexi goes past her TL Golfingly yours Zizzer I have never seen Joe Mayo or George Gankas explain to a golfer how to get to the Sam Snead "sit-down" look (squat position) by P5. They simply instruct the student golfer to get to that desired squat position. In my review paper on the biomechanics of pelvic rotation, I explained how it is performed secondary to activation of the right-sided lateral pelvic rotator muscles, which rotates the pelvis counterclockwise away from a weight-pressure loaded right leg/foot, while the golfer simultaneously activates their iliopsoas muscles which increases the degree of anterior pelvic tilt. I personally don't like the idea of extending the right side of the mid-upper torso during the backswing as that "lifting-up" motion can decrease weight-pressure loading of the right leg/foot. I think that a golfer should either maintain their spinal bend inclination angle unchanged or increase their spinal bend inclination angle slightly by increasing their degree of hip joint flexion to a small degree (as seen in Ben Hogan's, Rory McIlroy's and Tiger Woods' swing), which will cause the head to drop by a small amount. I think that many pro golfers get their left buttocks to move beyond the tush line in the late downswing (when they activate their left gluteus maximus muscle maximally and fully straighten their left leg), and I think that it is perfectly acceptable. I personally prefer a more limited amount of pelvic rotation during the backswing that optimally stretch-loads the right-sided lateral pelvic rotator muscles, and I do not favor a more exaggerated degree of pelvic rotation that gets the right hip joint very "deep". Jeff.

Dr. Mann,
Thank you for promptly replying.
"Drop the hips" (first video) has meaning to me but I will accept others might not understand.
Beyond that, you seem to have more a passion for conflict than for Golf, which is unfortunate as you do have interesting and informed insights.
Golf coaches, its seems to me, face the marketing imperative of "Differentiate or Die." This carries over to even its pundits. I recently watched Nick Faldo on video talk about rotation of the pelvis and weight shift. He is a bright man and it was transparent he was not about to say something in a way said by someone else. He was literally captured by his need to use his own professional jargon.
Golfingly yours,
Zizzer

You wrote-: "Beyond that, you seem to have more a passion for conflict than for Golf".
I disagree - because I have a great deal of passion for the pursuit of a deep intellectual understanding of the golf swing biomechanics/mechanics used by skilled PGA tour golfers that far exceeds my fondness for the back-and-forth conflict of intellectual debate.
Jeff.
