動画を拝見しました。開始9分45秒あたりで、「肘からクラブまでがヒモっぽくなる」という字幕がでますが、私には本当にヒモが出現しました!でもそれぐらいになるまで練習したいと思います。マジでテイクバックの右手肘の曲がりが気持ち悪くて仕方が無かったのです。こちらの動画を参考に練習に励みます。 PS. 予約購入していたご本、届きました。こちらも参考に練習します。
Kinetic energy=weight × velocity*2 , the only question is on how to increase the velocity of the club head, more specifically is the speed of clubhead's gravity center. There are two kinds of speeds: angular along the shaft and offset speed by spinning the shaft. They are created by changing the relative position of the gripping lines at both hands as quick as possible. So the issue is on how to limit the extent of motion & slow down the leading hand while forwad the trailing hand as quick as possible at the effective acceleration zone. What's important is the relative speed that creates "throw away effect"than the absolute speed for a "pull forwad effect " This zone should be quite narrow . Dustin Johnson use the trailing thigh as reference, as the baseball hitters do, Rory use both inner sides of thighs.
