发帖数: 31 | 1 正手问题不少
Set up. 不够，侧身不够，左手没有伸出去，是弯曲的，侧身不够击球时必然转体不够，
Set up release too early
After release 不应该有停顿，你明显有一个，影响动能，
引拍, backswing 弧度太大，再加上停顿，严重影响timing, which leads to ur
major problem,
No weight transfer when hitting, notice many times ur weight is still on ur
right foot when hitting, in stead, u should transfer ur weight to ur left
foot.
强烈建议你仔细学FYB 正手教程 |

发帖数: 234 | 2 Every good stroke has 3 basic elements - balance, timing and rhythm. You
have pretty good balance and rhythm but lack good timing partly because you
take your racket back too far. In the backswing, your racket points to the
left fence. If your racket only points to the back fence, you will have
extra 90 degree and more time to hit the ball in front of you, and your
follow-through will be longer.
Although the ping-pong style straight takeback is ok, imo it is better
to use C type takeback... 阅读全帖 |

因为compact backswing. 你的反手自己发力的话可能力量略差一下。但是接发球或者
受迫counter punch的时候很好用。
正手好像击球点太靠近身体了。所以看上去很快就开始雨刷动作了。当然已经很好了，
可能penetration没有完全发挥出来。 |

In this photo, Li Na demonstrates a classic square stance and backswing for
her two-handed backhand. Li's pronounced knee bend will help her legs
contribute upward and forward thrust to her swing, and getting her whole
body lower will help her handle this moderately low ball.

a Continental position and her left close to an Eastern forehand position.

用straight back swing主要是loop back swing总是找不到节奏，没办法。

发帖数: 420 | 7 Like it or not, Del Potro overpowered Federer with his forehand in the 2009
US Open final. His forehand is very effective and has a relatively compact
backswing which makes timing of contact a bit easier. It was once used as an
example on tennis.com. |

I think this article is good for you at the moment. timing your back swing
to make sure the motion is fluent - no stopping of the racket head at any
time. Your back swing start out too low, and has a stop.
it also has a classic post of starting of back swing - both hand along with
waist turn, eyes looking at the ball OVER the front shoulder. good luck

昨天终于深刻体会此道理。
由于我最近坚持跟教练练习，正反手和form 都进步很大。正手常常打出优美的上旋，
直逼对方底线；单反则是潇洒一挥，正中甜点，速度也不错。以上是 rally 练习时的
我。
可是，比赛开始了，老练的对手（一位五十多的中老年人）用变换方向，节奏和调小球
来对付我，让我 rally 练习时的感觉完全发挥不出来。就因为 Footwork 不好，差半
步，在 unbalanced 的情况下被迫挥拍，球感完全没了。
结论：明天开始练习Footwork，买几个 orange cones 先。

发帖数: 337 | 13 老三正手的主要问题，前面已有人指出，也与前不久bee谈论到的drop the racket毛病
类似，即拍头停置在最低点，对着来球再往上刷。
改进办法：把挥拍击球当作一个动作，takeback (or backswing) --->swing forward-
-->drop the racket head--->then swing from low to high--->accelerate &
increase the head speed---> hit--->follow-through 等等只是其中的环节，中间最
好不要停顿。
完成takeback之后，转腰与转肩积蓄能量(像上发条coiled spring一样，尔后向前挥拍
以释放那些能量)，如果挥拍中间需要停顿一下，那就是在takeback之后、释放任何腰
与肩部的能量之前，而不是在拍头降到最低点之后(drop the racket仅仅是为拍头加速
的步骤之一)。 |

好像backswing太大
感觉好像是因为你快击球时突然伸直了前臂，然后直着胳膊打，这样久了可能对胳膊冲
击比较大，容易得网球肘；二是引拍太大球快了来不及
推荐的drill是胳膊下夹个球，强迫自己弯着胳膊打？不过击球的距离和位置应该要相

1. keep the proper distance between the ball and body...看自己录像知道这个问

momentum反而小了而导致球速不够快。希望慢慢恢复打上升期球的timing。
2.侧身小幅度backswing时左手和拍子一起动。。这点好像文字解释比较难：）。。。
3.volley不要follow-through. 击球后拍子还要距离击球点比较近。。。。。
4.除了volley握拍放松只用2-2.5 out of 5的力气。。。 |

发帖数: 3845 | 25 不是绝对的，但适合一般的ralley ball。在backswing的开头阶段，左手指球和右手举

发帖数: 3845 | 27 还有球高低的位置(由你的屈膝来控制）。老三，你self feed可以试一试no-backswing
-forehand (还是需要full followthrough)，我有一次看到俱乐部一个人训练时就这样
打，直接Layback手腕, drop racquet head到contact point。只是给你一个Contact
Point的位置感，手腕有一些Layback，球拍head有30-45度的drop。无论刷不刷都要感
受到Solid Contact，然后Full Windshield Wiper（或tranditional)follow through
。需要用你的髋带动Core产生Swing speed。
你要注意有一个完整的随挥动作，这可能是你动作里最容易改，改了后立马好看多了的
一个要素。一个比较要学的随挥就好比你用右手去抱你的左臂，你的头看的到你的右肩
。随挥就像鞭子一样，很relaxed。 |

what method you are using? and how you adjust in the game?
I have bigger backswing, however, I am trying to have open stance and
shorten my back swing for my forehand, and have the weight shift from right
foot to left foot during the racket swing and ball contacting to build more
power. Lots of time I ended using close stance or sometime even worse I
just be lazy and use the racket to block back the ball.

发帖数: 3845 | 38 I feel similar. When returning fast serve, or when hitting quick passing
shot off deep slice, backswing could be just a little. The ultimate most
important thing is you swing the racquet to contact point in time in front.
So for whatever backwing loopy or compact, you need to make sure forward
swing in time to the hitting zone. |

发帖数: 3845 | 39 Yeah, in that case, it has to be a short backswing,and prepare to hit a 1hbh

Footwork, especially right foot step in (last step) is another story. It's
advanced and very important if one can hit on rise and always hit in his
comfort zone. |

发帖数: 1696 | 41 我喜欢你的评论，客观直接，一针见血。
我告诉他的是早转慢转，但是他体会不到那种随球转的节奏感，为了不击球晚，就变成
了早转快转，导致动力链的断档。我当过小孩子足球篮球棒球网球的教练，就为了能在
场上监督他。结果我发现孩子最重要的素质其实是那种自我推动的能力，就是自己想要
变好，去想怎么进步。很可惜我儿子没有这个素质，至少现在没有。我说什么他都认真
作，但是他只是认真作，从没想过自己怎么能作好，就比如这个backswing的节奏感，
只有自己体会一种办法去学。
你不妨评论以下我的问题吧，特别是反手，为什么是花架子？看着我自己觉得没什么毛
病，打起来就没有控制，能用的基本只有挡球这一着。

zverev: his backswing is very much like wta and reaches his contact point
with left elbow semi extended, which is a bit straighter than wta pros like
sharapova. I wouldn't call him a clean example demonstrating atp 2hbh.
