确是个提高感知灵敏度与提高稳定性的有效方法One of effective way to improve flexibility and stability

在推手时无论对手采用何种姿势，如果放弃用力作直接的对抗的意识，你就有无数的既能维持自身平衡，又能使接触部位“不顶不丢“地以不同的方向，沿着对手表皮轻灵滑动的选择自由度。你的选择自由度越大，对手能成功攻击的可能性就越小。
那种以操练某种固定的“实战”应用“模式来提高所谓”实战击技，我认为是公式化的，不可取的训练方法，容易造成顶牛式推手的恶果。

在此，灰衣者的双肘挥动太频繁，幅度也过大。这容易造成身体架构的松散。并会降低技击的反应速度。
2：36
要提高灵活性，最主要的是提高对外力的感知灵敏度，另一个重要因素是在调整平衡时，要提高能协调尽量多的关节的调控能力。这也意味使得体态与意识丰满，无隙

现在他的肘比先前稳定得多。动作也就显得灵巧不少

由于这些看来细微的改善，我已经感到较以前难于破坏他的平衡，说明这种练习方式的改变是有成效的。

During push-hands, regardless of the posture adopted by the opponent, once you abandon the intention of meeting force with force, you gain countless options. These options allow you to both maintain your own balance and keep the point of contact neither resisting nor collapsing, while lightly and smoothly sliding along the opponent’s surface in different directions. The greater your range of options, the less likely your opponent is to succeed in an attack.

Training methods that attempt to improve so-called “combat effectiveness” by repeatedly practicing fixed application patterns are, in my view, formulaic and undesirable. Such methods easily lead to force-against-force push-hands and its negative consequences.

Here, the practitioner in gray is swinging his elbows too frequently and with excessive range. This tends to loosen the body structure and reduces the speed of martial response.

To improve agility, the most important factor is enhancing sensitivity to external force. Another key factor is improving the ability to coordinate as many joints as possible when adjusting balance. This, in turn, means cultivating a body state and mental awareness that are full, integrated, and without gaps.

Now his elbows are much more stable than before, and his movements consequently appear far more nimble.

Because of these seemingly subtle improvements, I already find it more difficult than before to disrupt his balance. This demonstrates that the change in training method has been effective.
