I love this article.  This is a topic that I have been confused about for a while.  Everyone says stretch, stretch, stretch before working out.  They fail to say that static stretching is actually not good before work outs.  I have noticed in the weight room and running that I am weaker when doing heavy static stretches first.  I wish more people would understand this point.  I like to do progressive stretches before working out.  Static stretches afterwards.  It has worked great and kept me injury free so far!
