An article on the New York Times states "If you're like most of us, you were taught the importance of warm-up exercises back in grade school, and you've likely continued with pretty much the same routine ever since. Science, however, has moved on. Researchers now believe that some of the more entrenched elements of many athletes warm-up regimens are not only a waste of time but actually bad for you." -- This makes me feel a bit better about never stretching! :)
