Since there's a Yiquan history thread going on I decided to look up some Yiquan sparring, which there is a surprising amount of on the web given that in most ICMA, free-sparring clips nearly non-existent.

Let's talk about this clip:

What do you think about this clip? What's good? What's bad? What can you see in this clip that represents internal martial arts?

A couple of things to keep in mind:
1) They are hobbyists, not professional fighters.
2) It's clearly friendly/practice.
