roddick, murray, djokovic all hit with atp 2hbh. two things to check:
straight or bend of both elbows at contact point and the backswing.
as long as your non dominant elbow is straight from racket drop to contact
point and you have a non circular compact backswing, it is a atp 2hbh.
There are other details that differentiate but they are minor.
I don't think djokovic ever changed his 2hbh? his 2hbh has all
characteristics of an atp 2hbh.

下网。原因在于当球拍接触球时，已是强弩之末， 拍头速度不大，同时也没有足够的
随挥， 属于powerless effort 的打法。分析自己的录像后发现问题， 做了两项改进
。一是用open or semi open stance, 二是减小backswing 的幅度（这对所有的击球都
有帮助），现在的cc shot 比以前好多了。你的backswing 看起来不错，没有我
overswing的问题，改变stance后效果应该会很好。
我以前打golf.现在打网球就不打golf 了。我发现golf 和网球的swing原理极其相似。
我把golf中overswing的毛病带到网球里了。现在还在纠正中。 |

发帖数: 734 | 6 开始乱喷了, from limited sample：
你serve开始的动作非常像sharapova.
你的backswing has a very high shoulder, 类似 rafter, wawrinka.
然后right shoulder sinks with your racket drop.
从你backswing和racket drop 的shape 来说，如果要我猜这个serve是学谁的，那应该
wawrinka.
racket drop这一帧，你还可以胸部向上挺多一定，你的胸部显得非常casual没有被
stretch,基本面向侧网，而不是朝向球。这个胸部面向球的动作，主要靠腿。
很难看清 你的racket 横着，所谓big L那一帧，貌似有点拍面open过早，就是
pronation过早,不过这可能跟你的ｓｅｒｖｅ多为slice有关。
另外，个人观点，学习serve，在form基本正确的时候，是要能尽早利用到腿。why not
,如果有
glitch不是说明你用了腿，而是因为你长时间没用下半身发球导致不习惯。 |

对方已经上网，不是鱼死就是网破的情况。假设对方已经上网，一般来说cross court
基本上是送死，必须打出on the run DTL的dipping shot。这种球的步伐，准备，拍面
和随挥有什么窍门吗？
btw, 我的那个刚升4.5的球友这种球打得非常好，好像他拍子基本上在前面没有什么大
的backswing, 他说就是一个flip wrist的动作。但YouTube上的一些教程说准备必时候
须举高拍子，等等。我自己试打几次，如果要用reverse forehand follow through,
DTL的球不是飞了，就是打中拍框。好像如果我要打dipping DTL， follow through 在
上臂附近也可以。
另外步伐上，是不是最后右脚跨一大步时backswing, 然后左脚cross over的时候同时
挥拍？ |

预判 is very important to, your first reaction is to predict where the ball

sideway, have enough spacing (so that ball is in front of you, to the side

发帖数: 3845 | 9 这个简单，我猜你停顿一下的最主要原因是右脚最后一步跨的同时backswing还没有完

swing before reaching the contact point. 所以后来人都以此来区别WTA和ATP
forehand. 雨刷属于follow through阶段，不属于讨论范畴。ATP Forehand最大的特征
是backswing时拍头指向前，在最后一刻才摔鞭，因为拍头向前摔鞭行程更长，需要更
快速，timing要好，产生的power更大. WTA FH 最大特征是提前wrist lay
back (拍头一般不指向前)，甩鞭行程短，容易timing, 产生的power/rpm相对小些。

Practicing with the use of a ball machine could handicap a player compared
to playing against an actual opponent. Recent studies have shown some
differences in swing timing and movement coordination, when a player faces a
ball projection machine as opposed to a human opponent. We focused on the
time of movement initiation and on stroke timing during returning tennis

准确，精准，可以hit most of greens.
昨天上了回来后的第一课，经老师值得才发现自己的问题 － 虽然他以前就说过的。
于是今天就很容易的找会了感觉，我的long straigh pure driver shot又回来了。
但是iron就没那么准了，特别是几个wedges。
于是得出结论，对与不同的clubs, 从wedge (lob -> sand -> gap -> pitching wedge
-> 9 ->8 ->7 -6 ->5->4-> hybrid -> driver) ，要不要stance 不同，（从open 到
close),要么backswing path不同。
wedge 更需要travel在球与target的延长线上，随着long iron, 这个travel路径需要
逐渐inside。 |

发帖数: 10701 | 28 I would take the advice from those comments.
1. I would advise him to take this drill from V Jay.

2. loose the arms, relax them.
power comes from loose muscle. Intense muscle slows down the movement. |

做1/8的swing, 在家里地毯上就可以练习， 注意力在球与club face的sweet spot接触

发帖数: 10701 | 34 不过是挺误导的那理论。
任何时候backswing，重心基本上没在左脚的（对右手球员来说），spin angle很重要

最后导致的就是用手臂挥球杆，造成hook..
我现在的swing如果出什么问题，基本上就是hook，而原因就是在swing top时重心没转

发帖数: 10701 | 36 我以前的理解是这样的，golf swing重点是个swing这个词， swing a golf club， 就
该有整个“挥舞”这个概念。如果左手手臂伸直了，是不是更有这个挥舞的感觉呢。
-- 上面那个理解当然不是我的，是每位高尔夫教练和好的球员都试着灌输的一种“感
觉”。 swing a golf club就是要理解成一个连贯的平滑的匀速的动作。
从技术角度来讲，我们需要左手臂伸直，左肩转90度，腰部保持尽可能少的绕脊椎的转
动，同样包括膝盖，都是为了最大化能量的积蓄和释放。单看左手臂，如果想象脊椎是
个圆柱体的中心轴，肩膀是直径，左手臂就像是切线来拉动身体这个柱体，backswing
是个积蓄能量的过程，downswing是个释放能量的过程，我们希望这个过程能量最大化
，伸直的左手臂更能减少力量在其它方向的分解。
同样，如果考虑downswing, 球杆头在地面达到速度最大直，一个伸直的左手臂意味着
一个更长的半径 （例如钟表指针），当然是一个更大的速度。
还有一点也是为了更稳定的挥杆动作。

经过上课和自己琢磨了很多youtube上的swing vision，终于发现并改正我的最大的问

问题出在：
1.swing plane: 我的backswing离开了swing plane（1-plane），然后down swing的时
候就不容易回到正确的plane上来。是造成缺乏consistency的最大原因。
2.extension: 右肩（我是左撇子）在击球瞬间及followthrough的时候倾向于抬高而不
是保持在swing plane上，造成extension的时候的lag(是这么叫吧)甚至没有full
extension，球会或者slice，或者topspin.
3.trying too hard。这也是2的直接原因之一。
