First off, I hate to say it, but I'm pretty sure from the descrip that Chris just gave of producing force the "internal" way, he's pretty much way off base.
What was just described is more akin to "kinetic linking" say in the fashion that a boxer hits.
The second you initiate movement in your foot you should feel it in your hands. There's no delay.
Actually, scratch that, you should always feel "the ground" (in a metaphorical sense) in your hands.
How would that happen without "Kinetic linking"?
