well my story is interesting
i bought into the x factor, after hearing how tiger actively restricts his hip turn, due to his incredible flexibility. seeing him and charles howell, and trevor immelman and sean o'hair do this i tried it, and it actually worked and i hit it really well, espcially with the driver.
then i discovered a golf pro. i wont mention his name, as i'll proply break brian's rule about other teachers. anyway, he believed in keeping the arms infront of the body, and for the majority of golfers, to do this, they need more hip turn. he actually teaches alot of what brian teaches, like using the hips to push on the club and throw it to the top of the swing, and allowing the hips to release going back to get enough shoulder turn. i realised, it was the proper way to go, for me, and for the majority i believe, to do this.
i have played like this ever since and hit it as good, probly better, than before. it shows that you can play good golf either way. the aforementioned tour players are so flexible and toned they can do that, and it works. however, bubba watson, phil mickelson and vijay singh all allow the hips to turn going back.
i belive most players need to let their hips turn, imo, to play good golf
