"My internal background is mainly Yi Quan (Yao Chengrong line), very little chen tai chi and a bit aunkai. Besides that, I am finishing my MSc. in Health and Fitness and working at starting up my own business in Health/Fitness Empowerment. I am only mentioning this, because of this background I am always looking for exercises and methodologies that are evidence based and have a useful application for my clients.
The course includes PDFs, videos and Chris is very approachable and helpful via mail and facebook. In the PDFs Chris seems to follow a certain roadmap, where he offers meticulous step by step explanations what makes the internal body (dan tien, ming men, cross body connections, yin yang etc.) and how to build it. Most description of internal workings are often either abstract ramblings with not much value or pseudo-scientific explanations with the same empty value. You find none of this here! The same can be said about his videos. In one of his videos he showed a simple exercise called rowing the boat, where you learn to connect your dan tien/ming men with your arms. After his explanations and playing around with it, older Yi Quan exercises made much more sense.
If you are looking for a very fair priced online course, with an honest knowledgeable teacher and a good method for learning the internal body method look no further!"
