2020年8月22日星期六上午8:00 (中国时间），何家伟教练带领我们来学习《TOMAR20-5 庇身捶（英文）》这个视频。

陈老师详细讲解了实用拳法的招牌动作庇身捶。在掌握这动作的基本动作后，规矩的要求非常高，要全身配合才行。陈老师给了何家伟教练很仔细的改拳。视频导读写的要点一定要跟视频一起看。

Master Chen Zhonghua explans the Practical Method signature move: Fist Drape Over Body. This move requies coordination of the entire body. Master Chen gave Kelvin Ho a lot of detailed corrections. 

Notes:

2:48 The beginning of our movement must be at the end of the opponent's. There must be no gap. If there is a gap, everything is reset. There is no advantage for us.

2:53 Fist Drape Over Body Requirements:

1. Hand, Elbow and shoulder form a boomerang (a triangle missing a side). When we do Fist Drape Over Body, we must maintain the boomerang shape at all times with each arm. My problem was that I changed the shape of the boomerang (I opened my elbow specially). At the beginning of the move, I also didn't place my elbow at the right place. Master Chen corrected me multiple times.
2. The stance shouldn't be too wide nor too small. It should be wide enough to create a challenge.
3. In order to move the right boomerang, we need to engage the right shoulder and kua. Press the shoulder down while push the kua up. This will cause the tail bone to shoot up.
4. The right kua and left chest is a rod. It will become longer. The increase in length matches the rotation of the right boomerang.
5. As we do in with right elbow, the left hand will automatically go out and down in a negative circle manner.
6. The 3rd bone on the neck and the tail bone form an axis, which will extend or contract as the left and right sides of the move switch.

2:53 庇身捶要求：

1. 双反圈：手不能过中线。
2. 手、肘、肩是个开口三角形。做动作时，这个三角形不变形。我的问题是三角形的开口太大，肘没有放到合适的位置。陈老师改了我肘的位置几次。
3. 马步不能太大，也不能太小，刚好给自己一点挑战就可以了。
4. 要转动那个右边的开口三角形，我们需要右肩胯。右胯上顶、右肩压下。这个转换会使尾骨往上。
5. 右胯跟左胸是一根轴。这根轴会边长。这个变长是根开口三角形的转时配合的。
6. 收右肘的时候，左手会自动以反圈出去往下。
7. 颈骨第三节跟尾骨这根轴在庇身捶左右两边转换的时候会伸长缩短。
