发帖数: 2546 | 2 我05年开始学的，断断续续学了3个学期，
分别10，6，10次课，每周一次，每次半小时老师教，半小时自己练
老师开始是中年女士，后来是的50十多岁的gentleman，
带3－5个学生，有一学期只有我一个学生，
现在学会backward crossover，three－point turn，forward的inside edge，outside
edge练习
backward的inside edge，outside edge我只有一只脚能做。
每次差不多10刀，还是有点贵。
而且我看边上的高手，进步很慢，都在基本功反复的打磨，以期能有扎实的基础来做难
的动作。
我看他们经常一个学期就练两个动作。当然，如果有钱的，有教练教当然很好。
但是，我想知道什么时候就进入了这样的阶段？
到了这个阶段，我就应该想想是否调整投资在上课和自己练上的时间和钱了。
滑冰会跳和跳的好还是很不一样的，这也是滑冰的乐趣。

而且“跟我滑”我好像没有找全的：（
我现在课上再练one foot three turn，
backward 的edge以前没有练过，现在在苦练，将来跳了以后的站立全靠它了
我试过十几次跳半周的，成功了也站不了3秒钟，所以还是先苦练backward的edge，
什么时候能够撑个十几秒，我想就可以练跳了
我现在穿了有pad的裤子去的，自由练习的半小时，我一般摔二三十次。
不过，基本没有摔痛过，太爽了
你的水平都比“跟我滑”高了吧，你不是陆地都能跳一周半了吗。 |

发帖数: 1853 | 8 这个裁判的解释也是在搞循环逻辑，根本没有说清楚。。。
首先，这个球是不是fumble，如果是那只有holder能拿球前进。。。否则死球如果不是
，那只能理解为backward pass...
其次，如果是backward pass,那么pass hit the ground了，就应该是pass incomplete
...还是死球。而且规则里没有这时不是pass incomplete的例外。。。
这个Play如果holder直接把球传给Kicker的情况下是没问题的，以前LSU成功也都是这

发帖数: 5247 | 9 我已经说了，false start的判决是以“是否该动作是以draw offside为目的”的标准
来的。也就是说，false start是一种judgement call，像jet sweep这种，wing player是lateral或者backward move，且
明显就没有simulate action at snap，那一般都不会吹
我详细解释一下吧。每一次进攻状态是ball marked ready，position set，snap
begins。在position set之后，snap begins之前，所有队员，不能有任何action, shift或者类似
动作simulate action at the snap。如果裁判看到的是，在snap之前，某个侧翼球员做出
明显是进攻战术一部分的移动，那么裁判一般不会吹。注意这一点，这是裁判自己靠感

减力挡 is clear to everyone.
减力推 is similar to 轻推, but 减力 for controlling the distance and Rhythm (节奏).
减力挡 uses 减力 and 挡 but not 推.
减力推 moves forward and then backward quickly.
减力挡 stop to block and then moves backward quickly (does not move forward).

发帖数: 4225 | 19 I agree. I have found it effective to hit the ball really deep and vary
slice and topspin to play with him. Wide angle shots are not that effect on
him, unless they are very deep. Because he moves very well side by side,
but he almost never moves backwards. I kept telling him to move backwards
when the balls are deep. but you know what, he does not do that because he
is just so good at taking the ball early on the rise. |

is after a stroke I take a step or two forward, when the ball comes back, I
end up taking 3 or 4 step backwards, this also the key reason where my core
falls backwards.
Since I was never properly taught, my recover path is horizontal back to the
center, I need to move my neutral zone further back, and stay in my neutral

发帖数: 4801 | 26 姐姐呀，是这么的。
这个文章的意思是，第1步最重要，基本决定以后的balance和走向问题。所以如果第一步
太大，身体一旦完全stretch开，就没有后面的余量，从而使起伏和balance变得很困难，
这个刚好是我的毛病，以前我迈不开步，现在是迈得太大。所以第一步虽然很主要，但是
带着一点试探的味道，所以要适当，给第2步得起伏和保持做准备。
forward总是heel-toe
backward toe-heel
女士在backward的时候，如果比如是右脚起步，那么1上左脚应该release toe,就是说不
要绷脚面试图把脚留在floor上，而应该release toe,让脚底离开floor,这样大步就会很
容易。
