접영이 편해지는 과정 만드려면 이렇게 합니다. 연습&피드백 (나무늘보&응애물개)

Nothing gets easier for free! You have to create a difficult process to make it easier. You need to feel it during the practice process or while swimming. You need to train your water catch with the help of fins. 25m is nowhere near enough. You need to feel the water through repetition. If you practice in segments like 100m or 50m, you will understand where you struggle the most. That’s right. You just need to try to fix that part. The unnecessary tension. The reason I don't struggle even when swimming slowly is because I know how to release unnecessary tension. If you all create that process, you will be able to swim butterfly without tension!
