자유형 롤링 이해 하는데 걸리는 시간 5분이면 충분 합니다.(안힘들게 수영하는 팁)

Hello, this is Crawl Swim. I'll explain to you how to do a freestyle roll. This is my personal know-how, so it may or may not be the right answer. However, since it's my own style, I use it in competitions, there's no harm in following along. Each instructor has a different style, so it's up to you. Choose your own style, depending on your preference. The swimming style I pursue is one that allows for long, comfortable, and fast turns. Through consistent research, I was able to win first place in the national 3.8km long-distance swimming competition, and also set new Korean Masters records in the 800m, 400m, and 200m freestyle. If you can also follow my style and know-how, you'll soon be able to swim comfortably. I'll be rooting for you.
