Starting on your stomach, focusing on keep the hands about 6 inches below the
surface of the water, and pushing your finger tips directly forward. Use the
abs and hips to generate xxxxxx movements that travels through the feet, do
your best, not to bend your knees too much, but allow the knees and feet to
react to the movement of the hips.

Flip over on your and continue with the same movement. While on your back,
be careful not to allow your hands out of the water, but position them below
the surface, this will stretch out your abs and keep your back flatter.
With your legs, try to allow just the knees and a bit of thighs to touch
the surface of the water. How to do it really well for fine points? Think
about staying fairy ridges from your finger tips to your head, but allowing
your body to flow to the back, be careful not to brace to your palms at any
point of this drills, but spears with the finger tips. Also be careful of
allowing your hips sink while on your back requiring your kick and bend your
legs too much. If you are struggling for air, use the snorkel to allowing you
to practice for a long period of time.

簡單來說最重要蝶腿注重在你身體的流暢性
從你的腹部跟屁股帶動你的蝶腿
常見的錯誤就是身體沒有扭動 然後腿拼命的踢

換個姿勢身體朝上
身體持平 別讓屁股掉下去 不然就會腳彎彎的踢 這樣就錯了

ps. 就我個人的經驗就是 身體一定要放鬆 然後身體扭動像一條蟲子
就最重要的是腹部跟屁股movement 藉由著這個movement 蝶腿就能順勢被帶動
要注意的是不要刻意要求前進 導致身體變形 膝蓋彎曲
還有就是身體只有核心在動 而不是手臂跟肩膀也跟著瘋狂扭動
