Some pretty awesome movement demonstrated in the above clip.

A person would be hard pressed to witness the type of ability to expand and extend outward while simultaneously extending down and inward as demonstrated by BKF.Tremendous root and stability on display.Not to mention a certain alacrity of movement.And so much more.

It would be interseting to have some Bio Mechanical observations tossed around without the usual pissing contest that seems to accompany discussion of high profile martial art personalities.

In particular it would be educational to hear some thoughts on body size in relation to mechanics of movement.

As far as Hsing I goes it does not get much better than this.MO

I noticed this old post and took a look at the video. Pretty nice xingyiquan. What do you all think? Obviously there have been some interesting discussions about xingyiquan biomechanics lately with all the Jack Dempsey posts and the nice artle by Jake on Xingyi throws.

Well I could not hear any commentary on the vid, so I did not hear anything about biomechanics, but Kumar is supposed to be damn good. Never met the man.
I agree with my teacher that the Dempsey book is possibly the easiest, best their is on XY biomechanics.
I saw this one today at the bookstore, but did not have much time to look at it

Anyone own it? Got some awesome reviews, and looked akin to what Tim has taught me.

PS Thanks Richard on the compliments on the article. It has been very well received.

Sorry to be responding to a message that's so old.

I read it and didn't find a lot in there that I needed. I believe Mr.Pearlman has studied mostly Japanese forms and his analysis is more geared toward finding what works in there.

If you want books that really break things down, try Tim's books. The Chin Na book and Effortless Throws are the best I've seen.
