It is widely believed that you can’t learn martial arts from a book or DVD. This doesn’t stop teachers, some well-known, from producing books and DVDs year in year out in order to study their style. Also with the invention of Youtube there are all manner of instructional video clips available these days. So, is there a way or a time that you can study from video or books? How much back ground knowledge do you need? How much can one learn from a DVD? Is there a difference between seeing someone perform a technique in a sparring match/fight and you watching then practicing to watching an instructional video? What form would you like instructional videos to take?
