It was the best lecture ever. Among the types that Napro mentioned, I was able to apply it to the body only if I knew the theory first. Whenever my cheeks didn't fit, I kept modifying my body movements. I tried this and that. I didn't know what was right. Thank you so much for letting me know the exact criteria. What's a little disappointing is that there are too few lectures on how to use your arms and hands compared to how to use your body (pivot). I think I've watched every lecture 10 times including the downswing part. Every time I listen to it, I hear something important that I couldn't hear before, so I keep listening to it over and over again. I don't know if you remember me, but Jeon Ye-sung's professional swing on Instagram was so cool that I went to Suwon to take lessons only once. There's a crazy swing like this. I thought, "How am I supposed to hit the ball?" I mean, the video you know... I was like, "What... I can't even hit a ball. Why is it like a professional swing?"I think my skills have improved a lot since then. I'll go get another lesson later. Oh, do you remember when I asked for your autograph as YeSung's No. 1 fan? ^^ I can't forget the excitement of winning Jeon Ye-sung's professional championship when we were tied for the last round of the week.^^ Once again, thank you for leading golf so much fun.
