How to learn butterfly stroke? Request tutorials and guidance

Well, since I don't know your situation, I'll say a little more. I can tell you more specifically after learning more. Write it literally first.

1, the ability of body muscles is the first, insist on doing sit-ups and backs every day (exercise the waist, otherwise you won't do butterfly swimming), starting from 40 a day and gradually increasing to about 200 within 20 days. (this is alive, it varies from person to person and cannot be forced. )

2. Practice the butterfly leg first, straighten your hands forward, put your hands together, and use your waist to drive your legs to swing. Think about how the whip works. Only when the handle moves, it drives the whip in defense to swing, or see how dolphins can be used, and then look at the online (underwater) butterfly competition video.

3. Slide your hands backwards from the front of your body to your thighs at the same time (pay attention to the back part), then don't stop there, and immediately swing your arms out of the water with the strength of your back. (Appropriate flexibility depends on age, of course) Tighten your hands behind your back, bend over, turn your arms forward, and press hard.

4. Action combination: kick one foot when the hand slides down, and kick one foot when the hand swings out as a group of actions, with an interval of 1~2 seconds between each action (suitable for beginners).

5, once again remind, waist is the key! ! !

6. I have teaching videos, and I will send them to you if I want.

7. If you learn quickly and want to improve further, you can continue to ask me.

Since I'm still serious, let's adopt it.
