Core Thoughts

Sonnie Trotter of Cobra Crack and other various hard trad ascent fame recently posted an article on core strength on his blog (see a link to his general blog on the right). I read it and promptly forgot about it, until seeing this NYTimes article.

Notice any differences? I thought they contradicted each other, but now I think they both support the need for a well-rounded and developed approach to core strength, except that most people screw it up, by accident or misinformation.
