Seems like a real nice guy...good information for most beginners. He goes into some details ...that's good. If I were his friend helping him or giving suggestions I would have gave him some "interviewer Style" questions for him to answer. For example, (Knowing what I know about Taiji) I would have asked him to explain "relaxing the shoulder and sinking the elbow" in his Peng postures a little better. I would have gone into more detail about those.
Newer students often ask about how to change from one step to another (or strange direction) without feeling OFF balance or wierd. I use "open and close" to explain this...it's something that they find easy to comprehend. When you pivot open your foot...you also open your hip socket. Just saying every step can become a kick can also be a can o worms imo.
Other common questions beginners might ask are: 1) How or what parts of the foot takes the weight distribution. 2) what kind of shoes to wear If at all. 3) tones of breath questions and on and on...
At around 20min when he started to explain his wall push I was a little worried that he was going to give up one of my personal wall pushing secrets. I'm glad he didn't say it.
