If the link doesn't appear, type urban ninja in youtube!. It's the first video!. I'm in really good shape, and my endurance is great!. I really have no experience (I'm 15), but if I practice everyday for a decent amount of time a day (let's say four hours, how long would it take to get pretty good at it!? Thanks!.Www@QuestionHome@Com
