Followup to tip of the week.

The August edition of Backpcker magazine featured a piece by Southwest Editor Anette McGivney, called "How to Walk."  Get your thumbs out of your shoulder straps and swing your arms, she says.  This provides a stabilizing counter balance to the leg motion.  Use trekking poles - especially on steep terrain - for extra striding power and reduced impact on knee joints.  Adjust the pole height so your forearms are parallel to the ground when you plant pole next to foot.  Ask "The Hiker" for a full copy of the McGivney article.  This is the most detailed account of how to walk on trail, I have seen.
