In this book there were references to papers and books by Scott Kelso, a neuroscientist, of whom I have already heard before, but never actually spent time to research. Some of his books include Dynamic Patterns : The Self-Organization of Brain and Behavior and The Complementary Nature.
Thus, the Complementary Training is taken from the title of latter book. For more info about complementary nature, squiggle sense, coordination dynamic and complex systems I highly suggest checking the The Complementary Nature website.
What all this have to do with training and nutrition you ask? Well, keep on reading the blog.
