자유형 팔꺽기/팔꺾기 연습을 해도해도 안 느는 이유!!

"21m of mirrors have been installed on the pool floor!" (Mirror lanes installed) If you come to Jeong Du-hee's swimming class, you'll be able to see your swimming movements reflected in the mirror in real time while swimming, which will help you correct your swimming stroke and significantly improve your skills. I'm so excited! 😄👍 For inquiries about free trials, stroke correction classes, advanced classes, masters classes, and mirror lane free swim, please call 010-4670-7890 or feel free to text or KakaoTalk. The pool is located at Jeong Du-hee's swimming class in the Unbuk Culture and Sports Center in Cheongdam-dong, Gangnam-gu. ㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡ 1. ✔ Mirror-installed lanes, small group free swim program!
