Mark Sisson

I definitely think Mark Sisson's blog, Mark's Daily Apple, is a quality blog.  Lately, he's had two posts that caught my interest.  The first is his sprint video, which is available here.  After this, he posted his weekly workout routine here.  Mark is in great shape and as shown by his workout routine, he doesn't put in a zillion hours a week.  This shows that a proper diet (Paleolithic), and an efficient workout routine yields results.
