发帖数: 815 | 1 我现有的一些问题其实是历史问题。也就是我刚学golf的时候的一些潜意识的反应，所
以造成了如今的一些问题。
比如刚学golf的时候，说屁股上杆的时候不要向右平移，所以这也就是造成了我不敢把
重心往右移的心理。所以不知不觉的就重心往左了。那时看的一个drill是在右腿外侧
放一根杆，上杆的时候那根杆不能倒。我现在那个杆倒是不倒了，其实是。。。
还有就是ixcafe说的wrist cock不够早。这个也是有历史原因的。因为刚开始的时候，
教练说你不要过早的lift arms，应该是杆头应该先平着往右。因为太早lift arms，会
hit thin. 所以这就是我逐渐养成wrist cock晚的原因。 |

发帖数: 724 | 2 其实THING跟FAT的根源是一样的,STEEP SWING PLANE.我今年在一个LOCAL的GOLF SHOW
上听HANEY也是这么说的.另外,WRIST IMPACT POSITION也是很重要,如果你没有足够的
LAG的话,你就很难MAKE CONSISTENT CONTACT,不是THIN就是FAT.很多业余球友都是在
BOTTOM FLIP,导致THIN或是FAT. 你可以看看我的这个VIDEO,在这个VIDEO中我就FLIP
WRIST,导致LAG大部分都丢掉了, 虽然这个SOLID,但一直这么打的话很难CONSISTENT.

另外你的教练恐怕在教你STACK N TILT,这种SWING的中心一直在左脚.相对比较容易
TIMING,因为不需要先SHIFT BACK在SHIFT回FRONT FOOT.但SHIFT的好处是可以增加
SWING WIDTH,对于STEEP PLNE比较而言有好处,另外可以略微增加POWER.但坏处是需要

发帖数: 2325 | 3 you already fixed flipping? last time your swing video look very nice.
here are some i tried to correct flipping,
one big sign of "flip" and "no lag" is back of left wrist break during
impact.... so if consciously firm up left wrist at impact, and rehearse
timing 后发力, keep hands ahead of ball at impact.... that would help....
also left hands leading, don't let right hand over power the left hand...
there are ruler tied to left hand back drills (no very effective to me),
impact bag drills.... |

发帖数: 4031 | 4 heard of light grip pressure and know Fred Couples grips his clubs very
lightly while swinging. It doesn't work out with me. As for curing a slice,
I usually have a slightly strong left-hand grip, presetting the club face
close at stance, and I don't intentionally cock my wrists or let my wrist
angle change in the backswing. And I don't intentionally rotate up my left
palm at or after impact. |

his swing has very good leverage on wrist and hip.
several things i notice from his swing:
left arm fully extended from takeaway to 90 degree past impact,
right arm fully extend from impact to 145 degree past impact.
therefore hands are pulled far from his shoulder when

2) right arm 145 degree past impact
this is a REFLECTION of wrist leverage, wide SWING arc and classic release

wrist rotation is naturally done during swing, not that something you do it on purpose.

我最近的SWING 的路线准度不是能BREAK １００， ３０＋ YARD 以上的HOOK/slice 是
不能用在COURSE 上。
有几个DRILL 我觉得有帮助
１）慢速SWING ＆ HALF SWING， 体会SWING PLANE ＆ PATH ， 感觉你的手和球竿象
是在一个导轨上移动，同时可以体会和TV 上PRO SWING 的异同， RELEASE 的时候LEFT
WRIST 不要BREAK, also feel where is the deliver position, where to hinge &
unhinge your wrist。
２）BIG／FULL SHOULDER TURN， 这个ET 强调过， 但是怎么知道你有没有做好
SHOULDER TURN？ BUBBA WATSON＇S TIP －－－ KISS THE SHOULDER 挺好用的
３） 找到你最舒服发力的节奏, 保持BACK SWING 产生的扭矩, 跟重心转移配合好,
deliver的时候让扭矩释放.
you can do this |

有时候一些tip 也不一定起作用。
其实不容易用文字描述， 主要还是个人的感觉.
这一次我的感觉主要是不紧不慢 ,one piece take away， impact 时候open hip,
fully release with bowed left wrist & slightly bend right wrist, from inside
to out swing path. 节奏上调动人体的stretch reflex.

发帖数: 412 | 11 Use hip rotation for maximum club speed.
If you use hands or wrists for the swing and impact, you may find temporary
increase of distance, but there never will be consistency in your swing.
Slice, hook or even shank will be order of the day.
The hands and wrists should be kept in a passive manner through the swing. A
local PGA instructor should be able to help you analyze the swing and
points out the things that need to be addressed. |
