[技巧] 蝶式雙臂前擺入水的動作
以下是從網路上摘下來的蝶式技巧。我把幾處我認為有問題的標示成紅字。

The Butterfly Stroke
Similar to the breaststroke, the butterfly is also a difficult swimming technique, and not advocated for beginning learners, since it involves a fair amount of strength as well as precise timing. While performing this stroke, the legs should be moved together akin to the movements of a dolphin’s tail, the arms should also be moved together, pushing the water downwards and then backwards, while the torso moves forward in an undulating manner.

The Arm Strokes
之前左肩頰骨內在手臂轉到一定角度時會痛，過了許久才確定是游仰式引起的。在幾乎痊癒後，又開始練仰式，沒游多少(100m)，就又復發了。幾個月後，再次嘗試游了100m，也覺得不對勁，之後便不練仰式了。現在同樣是左肩與大臂的關節處，在手臂轉到一定角度時會痛，痛點改變了，前兩三周才發現，這近幾個月來的肩痛是練蝶式造成的－－雙手前擺入水時，甩得太用力了！－－入水時手臂外翻得太厲害。這是刻意學 Misty Hyman 的說！我想 Michael Phelps 那種體能與訓練，我應該是學不來的，所以選擇模仿女子選手。結果是弄巧成拙！畢竟女性的柔軟度通常好過男性許多。
▼剛好在網路上找到 Misty Hyman 雙臂前擺入水的動作。可以明顯發現她的雙臂前擺入水時，手掌面向外翻(內旋)。
▼ Misty Hyman 美妙的泳姿－－像極了一條美人魚。
最近仔細看 Phelps, 發現他是很輕鬆的前擺，（手掌向下，雙臂入水時也呈Ｖ型，非平行）；而不同於 Misty Hyman 雙臂出水後，直接甩向前，手臂外翻，入水時雙掌略為向外，雙臂平行。－－又是一個用受傷換來的寶貴經驗！－－左肩受傷，看來又要減少游泳次數，與每次練習的強度了。
▼ Michael Phelps 雙手前擺入水時，是很輕鬆的前擺，手掌向下
▼從靜態的照片也可以發現 Phelps 他雙肘微彎，所以手臂不是一股腦的甩向前，是先抬起來出水後再前擺。

The Arm Strokes
- The arms should be moved together, pulling through the water, while the hands are kept cupped. =>手腕為下彎，手掌自然用力，手指略開
- The palms should be faced outwards and pressed in a downward as well as outward movement. => 放輕鬆，入水後手掌再翻向外側(拇指內旋)為佳。
- The stroke is completed by swinging the arms forward in a sweeping movement while they are above the water.
- The knees should be kept together and slightly bent.
- Then the knees should be straightened, making a downward thrusting movement, while the feet are whipped downwards.
- For each arm stroke two kicking movements should be performed.
- A breath should be taken at the culmination of each stroke of the arms.
