Ken Gullette and InternalFightingArts.com
I did a search on "Ken Gullette" and "InternalFightingArts.com" and didn't come up with anything, so I thought I would try here. His site offers a "free 10-part course" where people sign up and are emailed a video outlining ideas on internal arts.
I'll post a couple links below. One is on "whole body movement". Here he discusses, about half-way through, an idea about "loading the lower back" and emitting kinetic force kind through a kind of wave-like motion from the feet up to the hands.
The other is a discussion on the dan t'ien and the kua. I'm not educated on this stuff, but it looks like the use of the lower abdomen and related core muscles to affect rotation while using the crease where the legs meet the torso to affect weight distribution in movement.
Can someone provide some perspective on this? Does this guy know what he's talking about, or are his ideas suspect?
