10 years ago, there was a man in VN discovered this secret. He instructed me to practice, but unfortunately he doesn’t yet completed the procedure to achieve the body, and technique. When I work around the Youtube, I just saw what DK did and trusted immediately and followed his instruction. After some month practice as his video my body and mind change much, much more before, my wife also discovers more effective than another. It is a great thing in the world. I believe.

Dear Master DK YOO, I saw your online lesson of WCS which is quite astonishing that your level of martial arts & intellectual achievements has already attained a certain highest level of my dream master of Bruce LEE(李小龍).

I have been following DK’s blog 3 years and now I’m so happy to open his online class. His philosophy is very powerful. And he reveals all his knowledge and skills that he learned, realized and experienced on this class. What I can do is just do it everyday, one by one, step by step. And now I’m adjusting my collapsed body and mind in this online class.

我练习中国内家拳(例如形意拳，太极拳等)多年，偶然看到DK YOO的视频，很震撼，他与中国内家拳的发力有很多相同的地方，有些例如腿部训练我觉得是我应该增强的地方，在训练课程中我受到了一些启发，并更系统的了解和学习了wcs。

By far the most complete online martial arts course out there. DK Yoo reveals everything required to move just like him. The perfect combination of ancient and modern training techniques all clearly presented and easy to understand. An absolute must for any serious martial artist.

Estoy muy contenta de poder acceder finalmente a toda la enseñanza de WCS aquí en México no ha habido ningún seminario, así que el curso en línea es la mejor opción que pude encontrar para aprender todo el universo de enseñanzas que tiene el maestro DK YOO. Gracias.

Since my son Joshua and I started training with master DK Yoo both New York 2 days class and online classes. I have never felt stronger and more fit. Thanks to the program it help condition both our bodies and our minds. I am grateful for everyone and master DK Yoo for their hard work on making the online training course which has been the key to our success.

So far the material is very well explained. Lots of metaphors are used to help further translate. The captions are good and come with very few grammatical errors. Overall I have learned a heaping amount and even made many more deeper connection in my craft. I’m only 40/179 into the videos. Highly recommend to coaches. Luckily for myself I did studying in many arts and I find the information given to be very relative.

Michael (ID: mikey90)USA

Every video is explained in a clear and simple way to understand and put into practice! Congratulations.
It’s perfect for all that can’t participate in live lessons but want study each day in depth.

De très très bons cours, bien filmés avec de bonnes explications. Une véritable immersion avec DK YOO! Je recommande à tous.

Kalo (ID: Kalo)France

I have only watched the first few videos, and have immediately opened my eyes. DK explains the concepts clearly and in simplest forms that are easily understood. Looking forward to finish watching all the videos, but I think it is better to take one step at the time. Thank you.

Dk Yoo is a real scientist and divulgator in the martial arts field. I’ve spent years and years in static exercise like zhan zhuang without real deep understanding. Thank to Master DK for his fantastic method and philosphy!
