(C) Quiet Upper Body
I became a big convert to this concept -- preached it on this newsgroup --
argued against anybody who tried to distract us from directing all movements
into _forward_ motion.

The point Bryan Fish made on this went something like this. The upper
body doesn't twist very much nor bend at the waist so much. But, it is not
quiet in terms of application of force. He teaches a very explosive curl
at the upper abdomen which proceeds the arms movement. So, if you picture
a head bobbing (slightly), the hands would stay with the head until that
curl was complete, and then the arms/triceps kick in to follow through. In
this way, a large muscle group is employed to initate the forward
movement, and the smaller arm muscles are gravy at the end. He showed me
many examples of world cup skiers, past and present who seem to use this
style, but Dahlie, classic skiing, was the most clear example.

I have definately not mastered this.
