Introducing email exchanges with golf lesson students (orthopedic surgeons).

This blog introduces "email exchange with golf lesson students". The person who sent the email is a "body professional (orthopedic surgeon)". The content of the email explained in an easy-to-understand manner what I noticed while learning the swing theory of  Taruki pro.

 Mr Taruki
Recently, golf practice has become fun. This is because i can understand the difference between the swings of other professional golfer and the golf swings of Taruki Pro.
I think that the essence of the Taruki  pro's  swing  theory can be summarized in three.
1. How to hold a baseball style
2. The grip on both sides should be maintained with the wrist joints dorsiflexed and slightly flexed during the swing.
3. How to use the lower body toward impact, that is, the right knee is sent to the right of the left knee, and smooth rotation is performed.
If you play golf like a baseball stance, the muscles of your whole body will be relaxed and you will feel better. I think this is because the strength of the wrist joints, elbows, and shoulders is moderately relaxed and it becomes easier.
With this stance, both wrist joints are also moderately dorsiflexed (slightly flexed), which seems to be the driving force for the smooth swing after that.
As the lower body moves, both hands can swing freely without doing anything.
"A break from the old golf theory" Will the right side be tightened with takeback? I think the swing of an elderly gentleman that appeared in the YouTube video of is ideal.
By the way, as I practiced the three essences, I got a little better.
Until the latest status report.

 Mr ,,,,,,,
I am very happy to receive your message.
From the message I received, I felt your passion for golf.
1. Baseball style stance
2. The grip on both sides should be maintained with the wrist joints dorsiflexed and slightly flexed during the swing.
3. How to use the lower body in the downswing (smooth rotation is performed by sending the right knee to the right of the left knee)
When it comes to how to move your body on a golf swing, I think it's okay to summarize the above three points. (If there are too many checkpoints, you will not be able to swing smoothly.) The above 1, 2, and 3 checkpoints are closely related. 
I also think that light dorsiflexion and mild flexion are the points. There is a difference in the perfection of the swing depending on how to maintain light dorsiflexion and mild flexion. Holding the angle created by light dorsiflexion and slight flexion with a downswing is the so called "tame"(holding and making time) swing technology.
It's my style of swing technique, but in order to more strongly hold the wrist "tame" made by light dorsiflexion and slight flexion, I "Hear the body bending both elbows a little at  the top of swing"  I swing the club near the body. Bending both elbows a little at the top of swing is similar to what you say, "1. Baseball-style stance." I think that the baseball stance (bending both elbows a little at the top of swing) is the key to using the muscles that contribute to the slight flexion of the forearm. 1 and 2 are considered to be closely related.
In order to make it easier to understand that the wrist joints on both sides are kept dorsiflexive and slightly flexed and maintained during the swing, I explain "the right hand is always up during the swing".
The way you think about swings changes greatly depending on how you use your wrist joints.
By having Mr. XX of the orthopedic surgeon teach you the points of swing, you can continue your golf lesson with confidence. Thank you very much.
